When a Filipino got Isekai'd with a twist!
" Only I can summon those!"
Chapter 5: "Dad!"
Smoke curled between the wreckage of shattered ballistae and burning wagons. Mephistopheles stood at the heart of it all—towering, black chains draped across his shoulders like a king's mantle. His crimson eyes locked on Lyra, his voice rumbling deep enough to vibrate the earth.
> "Princess Lyra of the Elven Kingdom… is that your name?"
Lyra's hands tightened on her staff. "…Yes."
The Demon King tilted his head, studying her as if reading something behind her eyes.
> "Then answer me this—do you know of one called Kieth Deyviel Martin?"
The name struck her like a stone to the chest. For a heartbeat, she forgot the battlefield around her.
> "Why…" she breathed, "would the Demon King of Incarceration… ask about him?"
Her mind spun. Kieth had been… taken—sent away to another world, his fate severed from theirs. She'd never spoken his name aloud since that day. How could Mephistopheles even know it? And why search for him now?
Mephistopheles took a single step forward, chains rattling like the toll of a distant bell.
> "Because he carries something… that belongs to me."
Before Lyra could speak, the air split with a sharp clang.
Kalisto dropped between them, his twin-bladed greatsword meeting Mephistopheles' massive weapon in a shower of sparks. The force rattled the ground, throwing dust in all directions.
Everyone froze for a heartbeat—not at the impact, but at the weapon in Mephistopheles' grip.
It was massive, angular, with a brutal, practical shape… yet its frame and grip bore an uncanny resemblance to Kieth's weapon from the Gundam RX-78-2—only smaller, as though reforged for a demon king's hand.
Kalisto pushed back, eyes narrowing.
> "Already you alright, Your Highness?"
Serena slid in from the side, catching Lyra under the arm and hauling her to her feet.
> "On your feet, Lyra—we can't let him close the distance."
Before Lyra could reply, a voice cut through the chaos.
> "Everyone on me!"
Sir Elara.
She sprinted forward, her silver armor streaked with mud and ash, longsword catching the fading light. Her charge was fearless, almost reckless, but her precision was undeniable—every step measured, every movement set to cut through the Demon King's reach.
Mephistopheles turned to face her, the corner of his mouth curling in faint amusement.
> "Another mortal seeking chains…"
Elara's blade sang through the air as she struck.
Sir Elara's blade met Mephistopheles' greatsword in a deafening crash. The shockwave blasted dirt and embers outward, forcing nearby soldiers to shield their faces. Mephistopheles didn't even budge—his massive frame absorbing the impact like a fortress.
Kalisto was already moving, sliding in from the Demon King's flank. His greatsword swept in a brutal horizontal arc, aiming to sever Mephistopheles' leg at the knee. The strike landed—only for black chains to erupt from the ground, wrapping around the blade and halting it mid-swing.
> "Pathetic," Mephistopheles rumbled, yanking the chains and forcing Kalisto to stagger forward.
That was when Serena struck. She appeared behind him in a blur, her twin daggers flashing toward the gaps in his armor. She found her mark—one blade sinking into a joint at the back of his knee—
—but instead of blood, oily shadows poured out, twisting and hardening into fresh chains that lashed toward her throat.
Serena rolled clear, but the ground where she'd been cracked under the chain's impact.
> "That's not normal blood…" she spat.
Lyra had hung back, staff raised high, chanting under her breath. A ripple of emerald light surged from her, weaving into the others—Kalisto's muscles tensed with unnatural strength, Serena's movements grew sharper, and Elara's strikes burned faintly with elven light.
Mephistopheles' eyes flicked to her.
> "So you're the support… Break the keystone, and the wall falls."
He moved faster than something his size should—one step and he was in striking range of Lyra. His greatsword came down in a cleaving arc—
Kalisto intercepted, his own blade catching the strike. Sparks burst, and for an instant, their weapons locked again. That strange resemblance to Kieth's weapon gnawed at him, but there was no time to dwell.
> "You're not touching her," Kalisto growled, shoving back.
Sir Elara seized the moment, rushing in with a vertical slash aimed at Mephistopheles' shoulder. This time she broke through—her sword bit into his armor, carving a shallow wound that hissed with smoke.
The Demon King's expression didn't change, but the chains reacted—dozens erupted from his back, slamming into the ground in all directions. The shock threw Serena off her feet, knocked Elara to one knee, and forced Kalisto to plant his sword into the dirt just to stay upright.
Mephistopheles raised his weapon again, voice low but carrying across the field.
> "You are insects… And I am the cage that will close around your world."
Lyra's voice rang out, defiant despite the tremor in her hands.
> "Not while we stand!"
Her staff blazed with light, roots of pure magic bursting from the ground to coil around his legs.
> "Now! All of you!"
Kalisto lunged. Serena followed from the side. Elara came from above.
Mephistopheles smiled—just slightly—and his chains began to move.
Kalisto's blade clashed against Mephistopheles' again, the sound ringing out like a bell. Serena slashed from the side, Elara came down from above, Lyra's magic bound the chains—
—but the Demon King barely moved. His red eyes swept across them, unreadable.
Then his mouth curved into a faint, cruel grin.
> "Hah… You call that resolve? That's not going to bring him back."
Lyra froze mid-chant.
> "…What did you just say? Bring him back? What is it to you that you're searching for a man who's already back in his home world?!" she shouted, voice cracking.
Mephistopheles didn't raise his voice, yet it carried over the clamor of steel and chain.
> "He wasn't sent by your goddess into his home world."
He took a slow step forward, chains dragging across the scorched earth.
> "He was sent back in ancient time…"
A pause—long enough for everyone to hear the next words clearly.
> "…then died there."
The battlefield went silent. Even the clash of steel from distant skirmishes seemed to fade. His voice echoed across the broken ground, letting every soldier hear the weight of it.
Lyra's knees buckled, her staff slipping an inch in her grip.
Kalisto's jaw tightened as he stepped forward, planting himself between her and the Demon King.
> "Lies! Everyone! Don't listen to him! It's just a tactic to make us lose our morale!"
Mephistopheles chuckled—a low, humorless sound.
> "Morale? Losses? Don't make me laugh, human. I don't tell lies… I tell only the truth. That's my father's teaching."
He tilted his head slightly, eyes glinting as if savoring the next words.
> "Don't ever tell lies to people that need it… so they can fully move on."
Lyra's eyes widened, breath catching in her throat.
That was Kieth's voice—his exact words—spoken in the tone he used when offering comfort to a friend.
Mephistopheles' gaze never left hers.
> "Tell me… how could I know about your necklace… if he didn't show it to me?"
Her hand instinctively rose to the small silver pendant hanging against her chest.
Then he reached into the folds of his armor… and pulled something out.
A chain. A pendant. The other half of the necklace—its broken edge a perfect match to hers.
> "Dad gave it to me… before he died."
The words hit like a hammer. Lyra's breath came sharp and shallow, her body trembling. Around her, Serena's grip tightened on her daggers, Elara's jaw clenched, and Kalisto's knuckles went white on his sword hilt.
The chains around Mephistopheles stirred, as if sensing the moment of shock.
The battlefield held its breath for half a heartbeat after Mephistopheles revealed the necklace. Then Kalisto broke the stillness with a roar.
> "You fucking monster! Don't mock our hero! Don't you ever taint his name for your twisted amusement!"
He charged, blade swinging with enough force to split armor.
Mephistopheles' expression darkened instantly.
> "Monster?! How dare you call me that! My father didn't call me that!"
Steel clashed, sparks scattering between them as the Demon King parried the blow in a single, fluid motion.
Kalisto gritted his teeth.
> "How the hell is he your father then?! He was human—and you're a demon kin!"
Mephistopheles' eyes narrowed.
> "Because I'm not. Not exactly. I'm not his daughter… but he still treasured me. Treated me like his own. He never discriminated like you humans. He treated all races as equals—with respect."
Chains writhed around him like serpents, but his voice dropped, carrying something raw beneath the rage.
> "He took me in after a rampant demon destroyed my town and killed everyone I knew. I was the only survivor. And even when the other gods and goddesses objected… Father—Kieth—took me in."
The sound of clashing weapons and distant screams seemed to fade as Mephistopheles' gaze drifted—not to the battlefield, but to memory.

[Flashback]
Ash. Smoke. The twisted skeletons of burned homes.
In the corner of a scorched ruin, a small demon kin child curled into herself, trembling, her horns singed and skin marked with soot.
A shadow fell over her.
> "Hey… you good? You got a name?"
The girl hesitated, voice barely a whisper.
> "Mi… pna… list."
Kieth frowned, kneeling.
> "Uh… well, I can't quite understand demon tongue or… whatever that was. How about I call you Mina for now?"
She blinked at him, then gave the smallest nod. Kieth smiled and scooped her up in his arms, holding her as though she were made of glass.
A few minutes later, Antares, Saint Lycana, Dern Riona, and Cique met him at the center of the destroyed town.
> "Hey man, we need to move. Another demon general might be nearby," Antares said urgently.
> "For once, the brute's right," Cique added, earning a glare.
> "Got a problem with me, old man?!" Antares barked.
> "Gods, the two of you…" Lycana muttered, shaking her head.
Their bickering stopped when they noticed the small figure in Kieth's arms.
> "Who's the brat?" they asked in unison.
> "Her name's Mina," Kieth said. "Found her curled up in a burned house. No one else is alive to take care of her."
> "Are you out of your mind, Kieth?" Dern Riona snapped. "She's an enemy! A demon kin!"
> "Yeah, and her kind's the most dangerous of the lot," Antares said, hand already on his sword.
Cique and Lycana stepped in before he could draw.
> "That's cruel, Antares. She's just a child," Lycana said firmly.
> "Maybe the next town can take her," Cique offered.
Kieth glanced down at the girl in his arms and shook his head.
> "This war's already made enough orphans. Let's not make more."
Reluctantly, they agreed to leave her in a nearby village.
But weeks later, that village was destroyed. Mina escaped alone, following Kieth's trail for days until she found them.
She ran toward him, voice breaking.
> "Dad!"
Kieth turned just in time to catch her as she jumped into his arms.
Antares burst out laughing.
> "Hah! A demon brat calling a hero her dad! What a sight!"
And from that day forward, Mina traveled with them—learning, fighting, and growing into the being who would one day be called Mephistopheles.

[Present]
Chains rattled as the memory faded from his eyes. Mephistopheles straightened, looking between Lyra, Kalisto, Serena, and Sir Elara.
> "That's why I carry his name. Why I call him Father. He saved me when no one else would… even your gods turned their faces away."
The four of them stood frozen, processing the weight of what they'd just heard. Lyra's grip on her staff trembled. Serena's usual sharp focus was gone. Even Elara's battle stance faltered.
Kalisto's sword arm wavered for the first time.
Mephistopheles' voice softened to a blade's edge.
> "So don't you dare mock him in front of me."
The air between them hung heavy with the weight of Mephistopheles' words. Even the battlefield beyond seemed quieter, as though the clashing armies were holding their breath.
Kalisto's jaw clenched. His pulse pounded in his ears.
> "You think that story excuses what you've done?!"
He lunged forward, blade screaming through the air.
> "I don't give a damn what you were to him! You're still a monster!"
Mephistopheles' chains whipped up like iron vipers, deflecting the strike with a harsh clang. Sparks showered the dirt. His voice thundered.
> "MONSTER?! MY FATHER NEVER CALLED ME THAT!"
The backlash from the parry forced Kalisto back a step. Mephistopheles advanced, every movement a predator's stalk.
> "He taught me never to lie to those who needed the truth… so they could move on. And I'll honor that—" His eyes blazed, voice dropping to a growl, "—even if it breaks you."
Lyra finally snapped from her shock.
> "Stop! Both of you!"
But her plea was drowned by the clash of steel. Kalisto pressed forward in a flurry of quick strikes, aiming for joints and openings. Mephistopheles twisted his massive greatsword—eerily similar to Kieth's Gundam blade—catching every blow with infuriating precision.
A sudden shift—Mephistopheles hooked Kalisto's blade with his own, dragging him off balance, then drove a boot into his chest. Kalisto staggered back, coughing.
> "Stay down, human," Mephistopheles warned.
> "Not… happening…" Kalisto spat blood, then charged again.
Sir Elara's voice cut through the chaos.
> "Everyone! On me!"
She dashed in from the flank, spear spinning in a silver arc aimed for Mephistopheles' ribs. Chains lashed out to intercept, but Serena was already moving—daggers flashing in under the distraction, slicing at the links.
For the first time, Mephistopheles was forced to give ground.
He snarled.
> "Fine… if you want the monster, you'll get the monster."
The ground beneath him cracked as his chains coiled and struck like hydras, each one tipped with a blade. The battlefield erupted into a storm of steel and shadow.
Kalisto, still panting, saw the opening in the chaos and dove in.
> "Lyra! Now!"
The elf princess raised her staff, her hands still trembling—not from fear, but from the ache in her chest at the truth she'd heard. Light began to gather at the staff's tip, a golden glow piercing the battle's gloom.
Mephistopheles' gaze locked on her.
> "So… you still think you can win after knowing what he was to me?"
Lyra's eyes narrowed, voice steady.
> "No… I'm going to win because of what he was to you."
The light gathering at Lyra's staff flared brighter, forcing shadows to recoil. Her voice rang out, raw and unyielding.
> "If Kieth really is dead… then you should be on our side, defending the world for his honor! If you truly see him as your father!"
Mephistopheles' advance slowed, his chains still coiling like restless serpents. His eyes narrowed, but a faint, mirthless chuckle escaped him.
> "Heh… You don't understand, elf." His tone was cold, almost pitying. "Yes, I honor father's legacy… but only after we kill all who oppose the Demon Lord Xandros. So he can revive him."
The words hit like a hammer blow—there was no doubt in his voice. He believed this.
Kalisto roared.
> "That's insane!"
Mephistopheles' grin widened, cruel and sharp.
> "Insane? No… I'm loyal. More than any of you ever were to him."
Before anyone could answer, the ground trembled—his chains lashed out in a whirlwind, forcing Lyra to break her casting to defend herself. Elara lunged in from the side, spear thrusting toward his flank, but one chain caught the shaft mid-strike, yanking her off-balance. Serena darted low, aiming for the gaps in his armor, but Mephistopheles twisted, his greatsword sweeping in a deadly arc.
Kalisto caught the swing with his blade, the force driving him to his knees. Sparks erupted where steel met steel.
> "You fucking monster! Don't mock our hero! Don't you dare taint his name for your twisted amusement!" Kalisto snarled, forcing his way back up and shoving Mephistopheles a step away.
Mephistopheles' voice turned ice-cold.
> "Twisted? Then tell me—who's more twisted? The one willing to destroy the world to bring him back… or the ones who let him die in the first place?"
The fury behind the parry sent Kalisto skidding across the dirt. Mephistopheles pressed forward, his movements blurring as the chains struck in perfect rhythm with his blade.
Elara spun her spear, cutting through one chain. Serena leapt onto another, running along its length to slash at the Demon King's helm. Lyra steadied herself and sent a bolt of pure light straight at his chest—only for the greatsword to absorb the blast with a flash of black energy.
> "You're strong," Mephistopheles admitted, stepping back a pace. "But you still don't understand. This isn't just my fight—it's his."
His stance shifted, both hands gripping the sword. Chains coiled behind him like the tails of a monstrous scorpion.
> "And for him… I will cut you all down."
The battlefield exploded into motion.
Kalisto dove in low, aiming for the knees. Elara struck from above, spear flashing. Serena danced in and out of the chains' reach, slicing wherever she could find an opening. Lyra called down beams of light that seared the ground, forcing Mephistopheles to keep moving.
Even so, he was never on the back foot for long. Every strike they made was answered with ruthless precision, every opening closed before it could be taken.
Then—Kalisto saw it. A fraction of a second where one chain had been severed and another was still recoiling. He went for it, blade high.
Too late.
The greatsword came around faster than his eyes could follow, and only Elara's desperate block kept the blow from taking Kalisto's head. The impact sent both of them flying.
Mephistopheles stood tall, barely breathing hard.
> "Is this the best you can do for father's honor?"
Lyra's magic began to glow again—this time brighter, hotter, her eyes locked on him with a new, burning resolve.
Lyra's chest heaved, her staff trembling in her grip. The truth still tore at her heart, but beneath it—rage burned hotter than grief. Her magic surged in answer, spilling golden light across the battlefield like a second dawn.
> "You want to see our best? Fine…" She stepped forward, the air around her beginning to hum, the ground under her feet fracturing from the sheer force of her mana. "I'll show you what he taught me!"
Her voice rose, sharp as a blade.
> "This technique—was taught to me by Kieth himself!"
The name rang out, cutting through the chaos like a bell. Even Mephistopheles hesitated, his eyes narrowing, a flicker of something—recognition?—passing across his face.
Light began spiraling around Lyra, each strand pulling tighter, faster, until the glow was almost blinding. The sigils beneath her boots pulsed with a rhythm like a heartbeat. She raised her staff, the magic forming a sphere so dense it warped the air.
Kalisto, Serena, and Elara instinctively backed away, shielding their eyes. The light wasn't just bright—it was alive, vibrating with a power that felt like it could tear the world apart.
Mephistopheles gripped his greatsword, chains snapping taut behind him.
> "That… I've seen that before."
Lyra's eyes locked on him, voice shaking with emotion.
> "Then you know exactly what's coming next."
The sphere of light began collapsing inward, condensing into a point so small it could fit in the palm of her hand—yet the pressure in the air was suffocating. Every loose stone on the field lifted into the air. The wind screamed.
Mephistopheles set his stance, his grin gone now.
> "Tch… Father really did teach you that."
Lyra's voice roared over the gale—
> "Radiant Judgment!!"
She swung the staff forward—
—and the world went white.
The shockwave was deafening. The ground split like dry earth in a drought. The blast carved a straight path toward Mephistopheles, shredding through his chains as if they were paper.
For an instant, his silhouette stood framed in the light… then the dust swallowed everything.
Silence.
The wind carried away the smoke—
—and there, at the very center of the crater, stood Mephistopheles. His armor scorched, one horn broken clean off… and a strange, dark light beginning to pulse from within his chest.
He lifted his head, his voice low but filled with something dangerous.
> "So… he did tell you about it."
The ground beneath him began to crack—not from the blast, but from something inside trying to break free. His greatsword shattered in his hand, fragments floating around him like pieces of a dying star.
Then—
A colossal shadow burst upward from beneath the battlefield, blotting out the sun. Its roar shook the sky.
To be continued..
