Nagae Estate
July 11, 2021 – Sunday – 10:00 A.M.
Riku's POV
Nearly half a day had passed since the festival, and honestly, the aftermath was nothing short of a headache. Tenshi's little "gift" didn't help either.
Ever since the performance, people wouldn't stop asking how my voice changed. I gave the safest answer I could think of — told them it took years of training and a ridiculous amount of effort to control, though it strained my vocal cords if I overdid it. A convenient half-truth. I wasn't proud of lying, but sometimes it's better to bend a rule than start an avalanche of questions I couldn't answer.
Most of them believed it. My childhood friends, though... their eyes said otherwise. They knew me too well to buy a clean story like that. So I told them if they wanted the truth, they could come to the estate today.
Now here we are — Rinko sitting beside me, Fuyu curled comfortably on her lap, and Kuroka perched right on top of my head. She's using senjutsu to speed up my healing, which I definitely need right now.
And the reason I'm still recovering? Tenshi. The moment she saw Albion after my performance, she challenged him. No warning, no hesitation — just pure Tenshi. And of course, the giant white gecko accepted.
Their "spar" wrecked my mindscape. The once-lush Dragon Palace grounds turned into a wasteland. Iku managed to preserve the palace itself, but my body felt every ounce of the damage. Pain still lingered like a dull fire beneath my skin.
Naturally, Iku wasn't amused. She punished both of them. Tenshi ended up chained and banned from the central hall until further notice, while Albion got exiled to one of his self-proclaimed "discovery islands" for two weeks. Iku even added a special condition for Tenshi — she'd have to use the Divine Dividing just to speak to me. Harsh, but deserved.
Kuroka lightly patted my head, signaling I was good to go. I reached up and gave her a gentle scratch in return. She purred softly — a small, satisfied sound.
Moments later, Kazehana appeared from the hall.
"Riku-sama, some of the guests have arrived," she announced with a bow.
I nodded, giving her permission to let them in. She slid open the door, and in came Aichi... with Kotori beside him.
"Aichi," I said, a bit surprised. "You brought Kotori with you?"
Aichi smiled slightly. "Remember, Kotori's one of Tenshi's childhood friends too. I figured she deserves to hear what's going on."
Kotori gave a polite nod. "I hope I'm not intruding."
"Not at all," I assured her. "You're welcome here. But we'll wait for everyone before I explain."
Aichi sighed — probably expecting as much — and they both took seats near the low table. The quiet between us wasn't awkward, just expectant.
It didn't last long. Footsteps echoed through the hall again, and soon Kaoru arrived carrying Kokoro on her back.
"We're here, ani-sama," Kaoru greeted.
"Glad you made it," I said, raising an eyebrow. "But... why are you carrying Kokoro?"
Kokoro mumbled, sounding half-asleep. "I'm still tired from all the selling~ Who knew Hagumi's event would be that exhausting?"
I couldn't help a small laugh. "Well, at least you learned something from it. Kaoru, go ahead and set her down over there."
Kaoru followed my gesture to an empty sofa and gently placed Kokoro down before sitting beside her.
"Let me handle something real quick," I said, lifting Kuroka from my head. The moment I set her on Kokoro's hair, the little cat-girl instantly knew what I meant. Her tail flicked, and faint ripples of senjutsu energy shimmered through the air.
Kokoro visibly melted into the cushions. "It's so warm~" she sighed, a blissful smile spreading on her face.
Kaoru watched in mild fascination. "Now that I notice... did you get another cat, ani-sama?"
I gave a half-smile. "Something like that. I'll explain when everyone's here."
Right on cue, Kazehana appeared again — this time with Ran, Chisato, and Chu² following close behind.
Ran was her usual calm self, though the faint dark circles under her eyes betrayed how little sleep she'd gotten. Chisato looked composed, but her gaze flicked around the room, taking in every detail — always observant, always assessing. Chu², meanwhile, crossed her arms like she owned the place, though the flicker of curiosity in her expression gave her away.
"I'm glad you could all make it," I began, glancing around the room as everyone settled into their seats.
Ran crossed her legs and leaned forward slightly, her crimson eyes narrowing. "I've got the same questions as Aichi."
Chisato folded her arms. "And I've got a few more. I even asked Maya-chan to help me think of extra ones."
I couldn't help a small smile. "I hope you went easy on her."
"I did what you advised me to do, onii-sama."
Of course she did. Always the diligent one.
Then Chu² spoke up, her voice sharper. "I know I wasn't at the festival, but LAYER told me everything. So, out with it— is it true that Tenshi's awake?"
I met her gaze and gave a small nod. "Yeah. Tenshi's awake. But as for speaking to her... this is the only way I can do that right now."
I lifted my right arm and summoned the Divine Dividing. A bright white-blue light spread outward as the wings of the Sacred Gear unfurled, radiating an aura that filled the entire room. The air shifted — heavy yet warm.
The girls — except for Rinko, Aichi, and Kotori — stared in awe.
"So that's the Sacred Gear you mentioned in Geitondei," Chisato murmured, eyes widening.
Kaoru took a step closer, her gaze fixed on the gleaming structure wrapped around my arm. "It's... majestic," she whispered. "But at the same time... ani-sama, may I?"
I nodded, lowering my arm toward her. "Go ahead."
Kaoru reached out hesitantly. Her fingers brushed the surface, and her expression softened. "I thought it would feel metallic, but... it's warm."
That caught everyone's attention. Ran leaned forward, her eyes narrowing in quiet fascination before she reached out too. "You're right... it is warm."
Chisato tilted her head, her tone mixed with curiosity and unease. "It still bothers me that a dragon lives inside this thing."
Kokoro, from her spot on the couch, raised her hand like a kid in class. "Onii-chan! I wanna touch it too~!"
Before I could respond, a familiar teasing voice chimed in. "You can't move yet, you're still recovering, nya~"
Every head in the room snapped toward Kokoro — or more precisely, toward the black cat perched on her head.
Chisato blinked. "...Did that cat just talk?"
Ran frowned slightly. "Pretty sure she did."
Kuroka gave a playful grin, her tail flicking. "Oops~ guess the cat's out of the bag, nya~"
I exhaled. "Ha... Kuroka, go ahead and introduce yourself."
Kuroka smirked, leapt lightly from Kokoro's head, and in a swirl of magic, her form shifted — fur fading into skin, her body expanding into her human shape. In moments, she stood before everyone in her usual attire: a sly, confident smile, golden eyes gleaming with amusement.
"Good day to you all~ I'm Tōjō Kuroka~ Pleased to meet you, nya~"
Before anyone could react, she slipped behind me and wrapped her arms around my neck from behind, pressing close enough that I could feel her warmth. The teasing weight against my back made it very clear what she was trying to do.
And she succeeded — just not with me.
"K-K-Kuroka-san!" Rinko's face turned scarlet as she rushed toward us, trying to pry Kuroka off.
Kaoru stammered, "O-Oh my..." while Ran just stared, expression unreadable but her eyes twitching slightly.
Kokoro, on the other hand, was all excitement. "Wow! That was cool! Do it again!"
Chisato's voice came out low and dangerous. "You... why are you so close to onii-sama?"
A faint dark aura began to rise from her. Kuroka noticed immediately — and instead of backing down, she smirked and leaned in even closer, voice dripping with mischief.
"Oh, come now, Chii-chan~ of course I'll be close to the one who took me in."
Before I could stop her, she tilted her head and planted a soft kiss on my cheek.
Every girl in the room froze.
Rinko looked ready to faint, Kaoru and Ran both went rigid, and I swear I saw steam coming off Rinko's head. Chu² just facepalmed while Aichi gave me a helpless, "you're on your own" look.
Then came a new voice — sharper, darker.
"Oi. What the fuck do you think you're doing to nii?"
We turned toward the sofa. Kokoro — no, not Kokoro. Shinzo. Her hair darkened slightly, her golden eyes glowing red at the edges. The air thickened with her aura, the pressure alone making the walls tremble. Behind her, two massive shadowy hands formed out of black mist.
Kuroka's grin only widened. "Oooh~ feisty~"
Before Shinzo could move, she suddenly froze mid-step.
"What the—Kokoro?! What're you doing?!" she growled.
It seemed Kokoro was trying to restrain her darker half from within, and for a moment, both sides struggled for dominance. I quickly stood up, pried Kuroka off me, and moved to Shinzo's side.
"Shinzo. Stand down."
She turned her head toward me, disbelief in her tone. "Nii... even you?"
I rested my hand on her shoulder. "Listen. Kuroka's just messing with you all. She loves provoking people — it's in her nature. But that's all it is. She's not a threat. Not here."
Her aura flickered uncertainly. I gave her a look — calm but firm, the kind that said trust me.
After a few seconds, she exhaled sharply, the darkness around her fading away. "Fine... I'll back off. But I'm keeping my eye on you, you thieving cat."
Kuroka chuckled as Shinzo's form softened, Kokoro's presence returning as she slumped back onto the couch, clearly drained.
"Aww, over already?" Kuroka sighed dramatically.
I crossed my arms. "Don't push your luck, Kuroka. You're lucky I talked her down."
She only grinned. "Still~ to think that little ball of sunshine has that much darkness inside her."
"That's Kokoro's other side," I explained. "Normally she wields light magic, but when she awakened her power, she developed a second persona — her dark side. We call her Shinzo."
Kuroka tilted her head thoughtfully. "Fascinating. Holy and demonic energies, coexisting in perfect balance... I'm impressed it doesn't tear her apart."
Kokoro, having caught her breath, raised her hand proudly. "Me and Shinzo have perfect control! Sometimes she even lends me her power, too!"
She demonstrated by conjuring a wisp of darkness in her palm — harmless but steady.
I gave a nod. "Thanks for the demo, Kokoro." Then I turned back to the Divine Dividing, the faint hum of energy still pulsing through the air. "Anyway, we're getting sidetracked."
I closed my eyes for a moment, focusing my will through the Sacred Gear. A pale blue light enveloped the room, gentle yet commanding.
"Tenshi," I murmured. "They're here."
I tapped the center gem of the Divine Dividing a few times, and the pale blue light began to pulse. Tenshi's voice echoed from within, cheerful and unapologetically smug.
[Hey everybody, how's it going?]
Chiyu leaned back, arms crossed. "So you're really awake now."
[Is that Chu²? How've you been? Still short like always?]
Chiyu twitched, her eye twitching along with her pride. Ran smirked faintly, and I could feel a wave of silent laughter from the others. I didn't interfere—Tenshi being Tenshi was unavoidable.
Before Chiyu could respond with something nuclear, Aichi stood, his tone quieter, steadier. "Nee-san... are you really there?"
[Aichi? Oh wow, been a long while. How's life treating you?]
Aichi chuckled softly. "Nothing much... just managing idols here and there. Busy, but it keeps me moving."
[Yeah, Riku mentioned that. By the way, how's the old fart doing?]
"Dad's fine. Still working, but I help when I can." Aichi smiled a little, though there was a faint catch in his voice. "And you? You're not giving Riku too much trouble, are you?"
[Trouble? Me? Nah, everything's perfec— GYAAAAHHHHHH!!!]
A sudden jolt of electricity burst from the Divine Dividing, sparks crackling across the metal. Tenshi's voice turned to screaming static, and the entire room froze.
When the light dimmed, a calm, familiar voice took over as Iku took control.
[Apologies for that interruption. It seems Tenshi still hasn't learned her lesson.]
Aichi's brow furrowed. "If I may ask... what did she do this time?"
[She tried to sugarcoat what happened last night. The truth is, she challenged Albion to a fight right after Riku's performance and completely wrecked his mindscape. His body is feeling every ounce of that backlash. I've since grounded her—literally. She's tied up in her room and forbidden from leaving the central area.]
Iku's words made the room still. Nobody dared laugh. Even Kokoro looked uneasy. Rinko's hand slipped into mine, her grip tight.
"No wonder you've been slow today," she murmured. "But how can you even move right now?"
Kuroka stretched lazily from her perch on Kokoro's head. "You can thank me for that, nya~. I used senjutsu to speed up his recovery. We youkai heal fast. But you, little one—" she tapped Kokoro's forehead with her tail, "—are not done yet."
With that, Kuroka shifted back into her cat form and resumed channeling her energy into Kokoro, who melted into the sofa with a blissful hum.
I exhaled, rubbing my neck. "Anyway, the reason Tenshi woke up earlier than expected is because I've been traveling through places with unusually high spiritual energy."
Chisato tilted her head. "You mean like... the Moriya Shrine?"
"Not just that," I said. "Also the Hakugyokurou."
Rinko's eyes widened slightly. "That makes sense. The Hakugyokurou is a hub of spiritual activity—souls, ghosts, all of it. It's pure energy."
[Correct. But that wasn't the only factor. The Divine Dividing itself accelerated Tenshi's recovery. The Longinus reshaped Riku's spiritual core—and in doing so, changed his physical body as well.]
Ran frowned. "Changed how?"
I sighed. "That's where the downside comes in."
Ran muttered, "I knew I'd regret asking."
"The Longinus' power is too much for a human body," I continued. "So to adapt... we had to sacrifice something."
[With a heavy heart, we discarded Riku's human side.]
Chiyu shot up from her seat. "Wait—what?! You mean he's not human anymore?!"
[Me and Albion had no choice. Either we did that, or Riku would've died instantly.]
Silence. Heavy and absolute. Everyone's faces mirrored the same expression — disbelief fighting against relief.
"Yeah," I said finally. "I'm not human anymore. Technically, I'm a humanoid dragon now."
To demonstrate, I focused energy into my left arm. Silver light flared, and scales spread across my skin, replacing flesh with polished armor-like plating. My fingers curved into talons that shimmered faintly under the sunlight filtering through the window.
Kotori leaned forward, awe flickering across her expression. "So... you can transform into a dragon now?"
I shook my head. "Maybe. Not yet. But if I can, I'll cross that bridge when I get there."
Kaoru's voice softened. "Ani-sama, have there been... any other changes?"
"Albion said I might be a little more competitive now," I said with a dry tone. "And... slightly more possessive."
That last word hung in the air like a drawn blade. The others exchanged wary looks, and I could see Rinko's brows knit together. They knew what I meant — what being 'possessive' could mean for someone with my power.
I forced a small smile. "Don't worry. I can keep the impulses in check. The only thing I can't promise is not getting too competitive."
Kokoro lifted her head, her voice small. "Onii-chan... you promise?"
I knelt beside her, brushing a hand across her cheek. I'd pat her head, but Kuroka was still nested there. "Kokoro, I don't make promises. I make guarantees. I guarantee I won't lose control, alright?"
She nodded, the tension easing from her face.
When I stood, Aichi stepped forward again. "One more thing... about last night."
[Ah, that. The reason Tenshi managed to take control of Riku's body is simple. She was at the core of his mind—the central chamber of the Dragon Palace.]
Ran blinked. "Meaning?"
"She's literally in the core of my being," I explained. "She used that position to seize control for a while."
Chiyu raised an eyebrow. "So you're telling me she could hijack your body whenever she feels like it? That's comforting."
[You don't have to worry. If she ever tries that again, she answers to me. And this instance was one-time only, for stabilization purposes.]
Chisato frowned. "Then... why do it at all?"
"Because I wanted to surprise all of you," I admitted. "Not exactly the safest method, but it worked."
There were no more questions after that. The tension finally broke.
"So," I said, stretching, "anyone up for lunch? I'll cook."
That earned unanimous agreement. Of course it did.
"Ran, Chisato, you're helping me."
Ran shrugged. "Fine."
Chisato nodded sharply. "Hai, onii-sama."
Aichi leaned against the couch. "What are you cooking?"
I looked around. "I'm open to ideas."
Kotori raised a hand, smiling softly. "How about Indian cuisine?"
"Good choice," I said, already pulling out my phone. "I know a few recipes."
"Kazehana!"
She appeared within moments, kneeling gracefully. "You called, Riku-sama?"
"I'm sending a list to your phone. Gather everything and send it to the kitchen once it's ready."
She bowed. "I hear and obey." Then she vanished as swiftly as she came.
I turned back to the others. "Let's kill some time while she's at it."
-----------
Scarlet Devil Mansion
2:00 P.M.
Third POV
When Riku said he would cook, he meant it.
Kazehana managed to gather the ingredients in record time—barely forty-five minutes—and soon the kitchen came alive with the rhythmic clatter of knives and the mingled aromas of spices. Ran and Chisato joined him, falling into a seamless rhythm as if they'd been doing this for years. For two full hours, the estate was filled with the sound of simmering pots, sizzling pans, and quiet laughter between the three of them.
When the meal was ready, the table was covered in dishes vibrant with color and heat: steaming biryani glistening with saffron and butter, bowls of creamy chicken thick with spice, and plates of garlic mushrooms sautéed to golden perfection. The fragrance filled the air like a festival feast. Riku, mindful of Rinko's delicate palate, had softened the spice just enough that she could enjoy it without complaint.
Even with their large group, the portions were almost excessive, and Riku ended up sending several trays to the estate's staff as thanks.
Lunch drifted by in easy conversation and warmth, but the quiet peace didn't last. After clearing the table, Riku mentioned that he needed to meet Patchouli at the Scarlet Devil Mansion. The tone in his voice made it clear it wasn't a social visit.
Ran asked him why. He simply replied that it was "something important."
Aichi, who had remained thoughtful through most of the meal, spoke up next. He asked if he could go with him. Riku was curious about the sudden interest, but Aichi explained he wanted to ask Patchouli something himself. That was reason enough.
The others planned to rest, but Riku offered to escort them home first. The girls accepted, and one by one, he saw them safely to their doors before heading to the Scarlet Devil Mansion with Aichi.
By the time they arrived, the afternoon sun was sliding past its peak, casting long shadows across the estate grounds. The mansion should've looked regal as ever, but what met their eyes instead stopped them in their tracks.
The wrought-iron gate was gone—reduced to a twisted heap of metal. Smoke drifted lazily from the scorched earth around it, and the once-pristine garden lay in ruin.
"What in the..." Riku muttered, stepping forward.
Aichi's eyes widened as he took in the scene. "What happened here?"
They moved closer, only to find Hong Meiling collapsed against the stone wall near the shattered gate. Her uniform was torn, her hands bloodied from combat, and bruises marked her arms and face.
"Meiling-san!" Aichi dropped to his knees beside her, panic rising in his voice. "Riku, how is she?"
Riku crouched and pressed two fingers to her wrist, focusing for a moment. A faint pulse answered him. He exhaled softly in relief.
"She's alive," he said. "But she needs medical attention. Badly."
"I'll stay here," Aichi said firmly. "Go ahead—find out what's happening inside."
Riku nodded once. "I'll leave her to you, then. Call Eirin-san if you can. She'll know what to do."
Without another word, Riku sprinted toward the mansion's entrance. But halfway there, his path was suddenly blocked by a wall of shimmering light. The air buzzed with condensed magic.
He stopped short, his expression tightening. "A barrier?"
Riku reached out, testing it with his hand. The instant his fingers brushed the surface, a surge of resistance shoved him back several steps. He caught himself easily, eyes narrowing.
"Whoever cast this," he murmured, "knows what they're doing."
Drawing a slow breath, he raised his right arm. The silver wings of the Divine Dividing unfolded in a swirl of blue light, the sacred gear pulsing in time with his heartbeat.
"Let's see how you handle this."
He pressed his palm to the barrier. The air rippled.
[Divide.] [Divide.] [Divide.] [Divide.] [Divide!]
Each pulse of the gear weakened the wall, strips of energy breaking off and swirling into Riku's arm as he siphoned the magic apart piece by piece. The energy was foreign—sharp and cold, not at all like the familiar presence of Remilia or Sakuya's enchantments. Whoever had erected it wasn't from the mansion.
A shiver of realization crawled down his spine.
"So someone really is attacking this place..." he muttered. His gaze hardened. "I need to find Remi and the others—fast."
But first came the one person who couldn't defend herself as easily.
"Flan," he breathed, already breaking into a run.
The mansion's corridors were eerily quiet, the air thick with dust and the faint echo of far-off combat. He followed the route by memory—the one Sakuya had shown him days ago, when she'd handed him a hand-drawn map of the sprawling halls "just in case." He hadn't expected to need it this soon.
When he turned a final corner, he froze. Two cloaked figures stood before Flandre's door, their presence dripping with an energy that made his instincts flare. It was dark, distorted—something he had felt once before.
"Wait..." Riku's eyes narrowed. "That's the same aura as Shinomiya Oko's..."
There was no time to hesitate. He flicked his wrist, activating the Water Webs of Heaven and Earth, and drew a violet spell card from his belt.
"Water Sign: Flying Fish Air Raid!"
Streams of water spiraled out from his bracelets, condensing into schools of gleaming fish that shot through the air like arrows. They crashed into the two intruders, bursting into mist on impact and forcing them back several meters. It wasn't much damage, but it was enough to open a window.
Before the cloaked figures could recover, Riku surged forward, coating his arms in dark-blue Haki. His fists struck like hammers, driving both attackers into the wall with bone-rattling force.
A flash of silver followed—the sharp, whistling sound of knives cutting through air. Blades pinned the figures to the wall before they could even fall. The cloaks disintegrated under the weight of magic, crumbling into fine dust.
Riku turned his head slightly, already sensing the familiar time-distorted aura.
"Sakuya-san."
The silver-haired maid stood just behind him, knives still spinning between her fingers before vanishing into nothing. Her calm eyes belied the chaos unfolding around them.
"Riku-sama," she said with a brief nod. "I'm relieved you made it inside."
"Remi mentioned Patchy wanted to talk," Riku replied, catching his breath. "But forget that for now—what's going on?"
"We're under attack," Sakuya said flatly. "We don't know who's behind it. The moment they took down Meiling, they erected that barrier. It's been preventing communication or reinforcements since then."
Riku's eyes narrowed. "Then how did you know I got in?"
"I didn't," she said, almost with a smirk. "But if anyone could bypass that spell, it would be you."
Riku gave a short nod. "I weakened it using Divide. Aichi's tending to Meiling-san outside."
"Ah. So Aichi-sama is with you."
"Yeah." He glanced down the hall toward Flandre's room. "What about Remi?"
"Oujo-sama is engaging the intruders herself," Sakuya answered. "She found their behavior... disrespectful."
That, Riku could imagine. The Lady of the Scarlet Devil Mansion never tolerated insolence.
Sakuya continued, "She ordered me to stay near imouto-sama in case anything reached her room. I assume that's why you're here too?"
"Exactly. I came straight to Flan first. Just to make sure."
A rare flicker of warmth passed through Sakuya's expression. "Thoughtful as ever. But your presence is needed elsewhere. The attackers are heading for the library—Patchouli-sama's domain."
That was all Riku needed to hear.
"I'll leave Flan to you," he said, already turning away. "If Aichi makes it in, send him to the library."
"Understood, Riku-sama." Sakuya gave a slight bow. "Good luck."
Riku gave her a single nod before sprinting down the corridor. The air seemed to hum with residual magic as he moved—proof that the battle ahead would be far from simple.
As he disappeared into the depths of the mansion, the faint sound of his footsteps faded into the growing storm of power emanating from the direction of the library.
Scarlet Devil Mansion – Great Library
Third POV
The Great Library of the Scarlet Devil Mansion, usually a realm of serene study and floating tomes, had turned into a war zone.
Thirty figures cloaked in darkness surrounded the heart of the chamber, their glowing eyes reflecting the chaos of battle. The air rippled with the scent of smoke and ozone. Books lay torn and scattered, spells danced like fireflies gone mad, and the marble floor was cracked from the strain of magic colliding.
At the center of the storm stood two women—one upright, barely, and the other unconscious behind her.
The first was unmistakable: pale skin, long lavender hair tied with ribbons that fluttered with every pulse of energy, and violet eyes that burned with fragile defiance. She wore soft, pink nightclothes—pajama-like robes trimmed with frills—and a crescent moon ornament on her cap that gleamed even in the dim light. Her name was known throughout Gensokyo: Patchouli Knowledge, the great magician and guardian of this library.
Behind her lay Koakuma, her loyal assistant, wings limp, her red hair spread like a pool of blood across the tiles. She was breathing, but faintly.
Patchouli's trembling hand was raised, maintaining a barrier spell that glimmered faintly around them. Each impact from the attackers' danmaku made it flicker, the transparent dome shuddering as though it might collapse at any moment.
"Surrender the grimoire, Patchouli Knowledge," one of the attackers declared, her voice smooth but sharp as steel. "Or suffer the wrath of my master."
She was unlike the others—taller, elegant, and far too composed for a mere foot soldier. Her long black hair flowed like silk, and her golden eyes gleamed with a predator's confidence. The black and gold gown she wore shimmered with woven enchantments, and the faint perfume of crushed jasmine followed her like an omen. Even the way she stood, poised and cold, exuded power.
Patchouli's lips curled faintly. "No way in hell I'm giving it to you. That grimoire contains more darkness than most could comprehend. I know exactly what you'd use it for."
The woman's gaze didn't waver. "Our plans are not for your concern. Hand it over... or watch your little servant die before your eyes."
Patchouli's jaw tightened. Her eyes flicked to Koakuma, lying battered near the base of a toppled bookshelf. The sight sent a stab through her chest.
She turned back, voice low but unwavering. "I won't give it to you. Even if this body breaks apart, I'll fight to the end. And I'll never let you lay a single hand on Koakuma."
The woman—clicked her tongue in irritation. "Then so be it. Your funeral."
Her command sliced through the air. "Finish them."
The mob obeyed instantly. Beams of light and streams of energy crashed into Patchouli's barrier. The impact shook the library; books burst into flames, the air thickened with dust and smoke.
Patchouli winced, her frail body shuddering with every blow. Her magic was powerful, but her stamina was not.
This is bad, she thought, chest tightening. Their attacks are stronger than before. My barrier won't last much longer... if I keep this up—
She coughed violently, her hand shooting to her mouth. When she drew it back, the pale skin of her palm was streaked with blood.
Damn it... someone... anyone... Remi, Sakuya, Flan, Meiling, Alice... Marisa... please...
Her voice cracked in her mind. The barrier shivered, cracks spiderwebbing through the arcane surface.
And then, the air screamed.
A flash of white tore through the library like the wrath of a god.
"Hakuryū no... HOKŌ!!!"
The roar of a dragon split the air, and a massive beam of white energy erupted from the far end of the hall, engulfing the attackers in a blinding storm. The very foundations of the mansion trembled.
When the light faded, silence followed. Books smoldered, the scent of ozone hung heavy—and where thirty enemies had stood moments ago, nothing remained but ash and faint embers.
Only the mysterious woma was left, her elegant form unharmed but her eyes wide with disbelief.
"What in the— That wasn't a spell card," she hissed.
A calm voice answered her. "That's because it isn't one."
Through the drifting dust stepped Riku, his arms encased in gleaming white dragon scales. His mismatched eyes—one crimson, one blue—were slitted like a beast's. The floor cracked beneath his steps as waves of dragonic aura rolled off him in quiet fury.
He stopped beside Patchouli, casting a glance toward her fading consciousness.
"Yo, Patchy," he said, voice softened. "Sorry I took my time."
Patchouli's lips curved faintly, her eyes half-lidded. "About... time... I'm glad..."
And with that, her strength gave out. She slumped against the wall, her vision fading into black.
The woman's gaze darted between Riku's form and the destruction he'd caused. Ephidel said this boy was a youkai, she thought, teeth gritting. But that energy... that's dragon. Pure, ancient dragon. Impossible...
She took a slow step back, assessing him. He wiped out my morphs in one blast. If I stay, I'll be next.
Riku's voice cut through her thoughts. "Now, before this gets worse—who are you, and what's your goal with that grimoire?"
The woman gave him a cold smile. "You've figured out more than I expected. But my identity isn't yours to know. I was sent to retrieve that grimoire for my master. And I intend to do so—by any means necessary."
Before Riku could reply, a sharp, aristocratic voice echoed from above.
"Ho~? Then I'll take that as a declaration of war."
The air shifted.
Descending from the upper balcony in a swirl of scarlet light was Remilia Scarlet, her wings flared wide, her aura pulsing with a regal fury that painted the room crimson. Behind her floated Izayoi Sakuya, knives gleaming in her hands, and Flandre, eyes burning with childlike anger and protective instinct.
The woman's mask cracked for the first time. She took another step back. The odds had turned completely.
Then—
"Sonia. Return to my side at once."
The voice didn't come from any of them. It came from everywhere. Deep. Commanding. The kind of voice that didn't speak—it imposed.
Sonia froze. "Lord... Nergal..."
Riku's eyes widened slightly. The name carried weight—ancient, dangerous weight.
The voice continued, calm but dripping with disdain. "Forget the grimoire. It is but a minor inconvenience. Let those insects play with it. We have greater designs."
Sonia lowered her head. "By your will, Lord Nergal."
A black portal tore open behind her, its edges crackling with crimson energy. She began to retreat toward it.
"Wait—" Sakuya snapped, her knives already mid-throw as she prepared to stop time. But then—
"—!!"
Her body locked in place. Her power didn't respond. The knives clattered uselessly to the floor.
Remilia looked sharply at her. "Sakuya, why did you stop?"
"I didn't," she hissed. "I can't use my ability."
The words hit like a thunderclap.
Riku and Remilia both tensed, realization sinking in. Whoever Nergal was, his presence alone suppressed space and time itself.
Sonia smirked faintly as the portal began to close. "Farewell, children of the Scarlet moon. Enjoy your borrowed peace while it lasts."
She vanished.
The portal snapped shut, and the library fell into an unnatural stillness.
Then—
"First and only warning."
Nergal's voice thundered once more, and the world itself seemed to shudder. An immense pressure flooded the room.
Riku gritted his teeth, his legs shaking under the invisible weight. Even the Scarlet sisters were forced to their knees, their wings trembling from the sheer force of it. The air itself seemed to warp, like gravity had turned against them.
Remilia's crimson aura flickered. Flandre clutched her head, grimacing. Sakuya struggled to breathe, eyes locked on Riku as if silently asking what kind of monster could radiate such power without even being present.
Nergal's tone was cold and absolute. "Stay out of our way."
And then—he was gone.
The crushing weight lifted instantly, leaving only the echo of his words in the air.
Everyone gasped for breath. The silence that followed was deafening.
Riku straightened slowly, wiping the sweat from his brow. "...So that's the kind of opponent we're dealing with."
Remilia floated weakly back to her feet, her wings twitching. "Even I could barely move. That wasn't mere intimidation—that was divine suppression."
Sakuya steadied her mistress, her usual composure shaken. "I've faced gods before, but that presence... it wasn't human. Not even close."
Riku turned away, crouching beside Patchouli's limp form. He checked her pulse carefully. It was there—weak, but steady. Relief flickered across his face.
"She's alive," he said quietly. "But she pushed herself far too hard. Her mana flow's unstable. She needs medical treatment now."
He turned to Koakuma next, resting two fingers near her neck. Her pulse was stronger, but faint tremors ran through her body.
"She's just unconscious," Riku murmured. "Took a direct hit from a spell card. She'll wake up, but not soon."
Remilia and Flandre descended beside him, their expressions softening as they saw their injured friend.
"How is she, Riku-boy?" Remilia asked, her voice unusually gentle.
"Patchy overextended her magic," Riku replied. "Her heartbeat's faint but steady. Koakuma's injuries are moderate. She'll recover, but Patchy needs immediate care."
Remilia's expression hardened again. "I see. Sakuya—take Patchy to the hospital wing. Have the maids prepare the infirmary."
Sakuya nodded briskly, already moving. "Understood, ojou-sama."
Remilia turned back to Riku. "And you—can you contact Eirin?"
"Aichi already did," he said. "She should be on her way."
Remilia exhaled slowly, her crimson aura fading. "Good. Once Patchouli's stable, we'll regroup. Whoever this 'Nergal' is... he just declared war on all of us."
Riku glanced at the scorched remains of the library, his expression unreadable. "Then he's going to regret underestimating this mansion."
As Sakuya lifted Patchouli's fragile body in her arms and disappeared down the corridor, the remaining three—Riku, Remilia, and Flandre—stood in the ruined silence.
The Great Library, once a sanctuary of wisdom, had become the first battlefield of a war none of them had expected to face.
----------
Scarlet Devil Mansion – Remilia's Office
5:30 P.M.
Riku's POV
The afternoon had been nothing short of chaos. By the time I finished calling every family head available for an emergency meeting, the Koumakan looked more like a battlefield than a home.
I spent the next hour helping Sakuya-san and the fairy maids patch up the damage. The once immaculate crimson halls were riddled with holes from danmaku impacts, and shattered glass sparkled faintly across the floor. Even for the Scarlet Devil Mansion, known for surviving incidents that defied logic, this attack had hit harder than expected.
Meiling-san arrived soon after, her right arm bound in a cast, with Aichi supporting her good side. Despite her condition, the ever-stubborn gatekeeper insisted she was fine to resume guard duty until Remi herself ordered otherwise. Her glare didn't soften even after Remi told her to rest.
Once Eirin-san was finished checking on Meiling-san, I filled her in on Patchouli's situation. The moment she heard how strained Patchy's condition was, Eirin-san's tone turned grave. She wasted no time heading straight for the hospital wing, prioritizing the librarian's recovery over everything else.
Not long after, Yuyuko-san appeared, gliding into the mansion like an elegant breeze that ignored all sense of urgency. She'd sensed the earlier clash from Hakugyokurou, worried about what might've happened. When I told her I was fine, she smiled faintly, relief hidden behind her usual airy grace.
Then came Orin and Satori-san. The latter had a sharper edge than usual—her eyes serious, her posture tight. With Remi's approval, she began her investigation almost immediately, asking for details on what we saw and heard during the battle. Her quiet precision made it clear she'd already pieced together half the story before we even began.
By late afternoon, everyone was gathered in Remi's office—Eirin-san, Satori-san, Orin, Aichi, Yuyuko-san, Remi, and Sakuya-san. The atmosphere was tense, the air thick with expectation.
Remi broke the silence first. "We're wasting time here. Let's get this meeting underway."
Yuyuko-san shook her head gently. "Not yet. Yukari and Okina should be arriving right about now."
Almost on cue, the air shimmered. A violet gap tore open beside the office window while a crimson gate manifested across the floorboards. From the first emerged Yukari-san, her golden eyes half-lidded with that perpetual air of mischief. From the second, Okina-sama stepped out, elegant and composed as always in her wheelchair.
Okina-sama brushed invisible dust from her shoulder. "We have arrived. My apologies for the delay."
"I heard everything from Ran," Yukari-san added, her fan snapping open. "Let's not waste any more time."
Everyone nodded. The meeting began.
Satori-san started first, sharing what she'd learned from her readings of those involved—and from the residual psychic impressions left in the mansion itself. Her calm, analytical voice filled the room as she summarized the attack: thirty unknown aggressors, led by a woman identified as Sonia, who referenced serving someone named Nergal.
By the time she finished, the heads of the families wore matching expressions of frustration.
Yukari-san exhaled softly through her fan. "I predicted they'd make their move next month... but I didn't expect them to act this soon."
Okina-sama's eyes narrowed. "You knew an attack was coming?"
"I had reason to suspect," Yukari-san replied. "A few of my people were tracking their movements."
Okina-sama folded her arms. "Let me guess—the 'people' you're referring to are Black Fang remnants."
Her tone was sharp enough to cut through the room. All eyes turned to Yukari-san. The gap youkai chuckled quietly behind her fan.
"Yes," she admitted. "But don't worry—they're on a tight leash. They've been under my watch since entering here in Japan."
Satori-san raised an eyebrow. "You recruited assassins to spy for you?"
"Correction," Yukari-san said, lowering her fan slightly, "former assassins. Before they fell into Nergal's shadow, the Black Fang were mercenaries—highly skilled, discreet, and motivated by something other than gold. I offered them protection, since Nergal's forces seem to have marked them as targets too."
Okina-sama sighed, rubbing her temple. "You and your morally gray solutions."
Satori-san nodded. "Still, if they're also being hunted, that means Nergal's reach is wider than we thought."
Remi drummed her fingers against her desk, crimson eyes narrowing. "And his power is no joke. I've felt divine pressure before... but this was different. It wasn't just magic—it was pure domination."
Her gaze flicked toward me. "Riku, you said you heard his voice?"
"Yeah," I replied, my tone low. "Didn't see him. But just hearing it was enough to make my knees buckle. Even Remi and Flan couldn't resist it."
A hush fell over the room.
Yukari-san's expression darkened slightly. "A pity you didn't see his form. But that confirms my fear."
She turned toward Sakuya-san. "You said earlier you couldn't use your time stop when Sonia escaped. Can you describe what happened?"
Sakuya-san inclined her head. "Hai. The moment I activated my ability, I felt something cut it off—cleanly. Like someone had disconnected my magic from reality itself."
Satori-san's eyes narrowed. "That would mean... we're dealing with a magic suppressor. A high-level one."
Yuyuko-san frowned. "If this Nergal created it, we're at an extreme disadvantage. We wouldn't even be able to rely on spell cards."
The tension in the room deepened until another voice entered from the doorway—smooth, calm, and unmistakably composed.
"If that's the case," Eirin-san said, stepping in with her usual poise, "then we may need to depend on something other than magic. How about we use the Lunarian Armament Project?"
Remi turned immediately. "Eirin-san. How is Patchy doing?"
Eirin-san clasped her hands behind her back. "I've done what I can. She's stable for now, but she won't be casting spells for at least a month. Any strain could reopen her internal wounds. I've assigned Udongein to watch over her."
Relief flickered across Remi's face. "Good. That's one less life I'll have to avenge."
Yukari-san tilted her head. "Eirin, you mentioned something about a 'Lunarian Armament Project.' What exactly is that?"
Eirin-san nodded, as if she had expected the question. "I was planning to present this at the next council meeting, but given our current situation, you might as well hear it now."
She approached the desk, producing a tablet-like device from her sleeve. "The Lunarian Armament Project is a collaborative effort between Earth and the Moon. It merges Lunarian technology with Earth's engineering principles to create combat systems that don't rely on magic."
Okina-sama's brow arched. "You're building weapons that can function in anti-magic environments."
"Precisely," Eirin-san said. "If our enemies can suppress our spellcraft, we must be ready to fight them on their own terms. The Watatsuki sisters are overseeing production. So far, we've developed a few prototypes designed for both defensive and offensive use."
Aichi leaned forward, intrigued. "Do you have any samples?"
Eirin-san's lips curved slightly. "Of course. I had Udongein volunteer as the beta tester."
She turned the tablet toward us. The screen displayed Udongein standing in a sleek, dark jacket with a formal cut and cape-like drape, balanced by a light skirt beneath. Black thigh-high stockings met polished boots, and across her back were two flat, metallic panels that resembled sonar wings. In her hands was a weapon unlike anything I'd seen—a rifle with a spiral-like structure, its barrel shaped like a horn. It pulsed faintly with an ethereal blue light.
Yuyuko-san whistled softly. "My, my. She looks rather stylish for a soldier."
Remi leaned back in her chair, her crimson eyes glinting as she studied the image on Eirin-san's tablet. "Ho~," she mused with amusement, "a very interesting design."
Satori-san tilted her head, her eyes narrowing with curiosity. "Hmm... but what are those two plates on her back?"
Eirin-san zoomed in on her tablet and replied calmly, "According to Udongein, those plates act as projectors and trackers for electromagnetic pulse waves. They allow her to manipulate the battlefield by detecting and countering any magic-based signals. Essentially, it's a replacement for her ability, since once someone dons this suit, their own innate ability is temporarily suppressed."
Yuyuko-san hummed softly, swirling the teacup in her hand. "A system that turns abilities off while compensating through tech... quite the Lunarian approach." Her tone was light, but the sharpness in her gaze didn't escape anyone. "Tell me, Eirin, how many of these armaments have already been made?"
Eirin-san gave a faint sigh. "Currently? Udongein's prototype is the only completed one. The rest are still under assembly. They should be finished once the gathering concludes."
A quiet wave of disappointment washed over the room. Even Remi's wings twitched faintly in irritation.
Aichi crossed his arms. "Are these armaments restricted to Lunarians only?"
Eirin-san shook her head. "No. We've selected a few individuals from Earth as well. Of course, all with consent. However..." she hesitated briefly, "including Udongein, we can only produce nine armaments in total."
The tension deepened. Only nine. That number was both a relief and a concern — too few to form a true defense, yet enough to signify the project's seriousness.
Remi sighed, tapping a manicured finger against the arm of her chair. "So nine weapons to prepare for a war we can't even see coming yet. Wonderful."
My voice broke the silence. "Eirin-san, may I ask who the other candidates are? Aside from Udongein."
The Lunarian doctor smiled faintly, her tone carefully measured. "I can't disclose their names yet. But I can share their codenames."
Okina-sama raised a brow. "You gave them codenames?"
"Of course," Eirin-san replied smoothly. "Each represents their role within the project. Listen carefully." She tapped her tablet again, revealing a list. "They are: Lunar War Shaman, Lunar War Enchanter, Lunar War Servant, Lunar War Oracle, Lunar War Soldier, Lunar War Gardener, Truth Temple of Legitimacy and Integrity, Peace Temple of Modesty and Devotion, and Plentiful Temple of Wealth and Equality."
The room fell silent as the words sank in — poetic, almost ceremonial.
Yukari-san broke the stillness, lowering her fan with a soft flick. "So these are the Nine Lunar Armaments." A faint smirk tugged at her lips. "I'll look forward to seeing them at the gathering."
Eirin-san inclined her head. "I appreciate your understanding. The project's secrecy is necessary until its completion."
I exhaled quietly, glancing toward her. "Eirin-san... about Patchy. When will she wake up? That's the reason I came here, after all."
Her expression softened. "Sadly, not for another month. Her magic reserves are completely drained. Combined with her weak constitution, recovery will be slow. For now, she must refrain from using magic entirely."
The heaviness of those words hit me like a dull ache. "I see." I paused, then nodded resolutely. "Then I'll be taking my leave."
Remi stood, brushing down her skirt as she met my eyes. "It's unfortunate timing, but it can't be helped. Go on, Riku-boy. And..." her tone softened, genuine for once, "thank you. I'm sorry for dragging you into this."
I chuckled faintly. "Nah. If we hadn't come, Patchy and Meiling-san might've been dead. You don't need to apologize."
Remi's lips curved into a rare, sincere smile. "Even so. On behalf of the Scarlet Devil Mansion..." she lowered her head in a small bow, "thank you for saving my friends."
Her gesture caught me off guard — Remilia Scarlet, bowing. I simply answered with a quiet, sincere smile of my own. Aichi, standing beside me, gave a respectful nod before we turned and made our way out.
The hall beyond was quiet again, though the faint hum of magic still lingered in the air.
Aichi broke the silence first. "In the end, you didn't get the chance to ask Patchy your question."
"It's fine," I replied, shrugging lightly. "Things changed after that attack. You have your own matters to handle, right?"
He nodded. "Yeah. I need to head home and report this to my father. Nergal's name alone is enough to send our council into a panic."
"I figured as much." I slipped my hands into my pockets, my mind still circling the earlier battle. "Do what you need to do. I'll inform my grandfather as well. And... send someone to protect Honoka and the others. If Nergal's willing to attack Remi this openly, then we can't assume anyone's safe."
Aichi's eyes hardened in understanding. "You're right. I'll make sure of it."
We stopped near the mansion's grand staircase. For a moment, the tension eased, and both of us exchanged a silent nod — one of shared burden, the kind forged in chaos and fire.
Aichi stepped away first, heading toward the exit. "See you soon, Riku."
"Yeah," I said, watching him disappear through the doors. "You too."
As his footsteps faded, I turned back toward the hall one last time. The scent of dust and gunpowder still hung faintly in the air. The mansion, though repaired, carried the weight of what had just occurred.
Even in victory, it felt like the quiet before a far greater storm.
