The Family Lounge on Beta Floor 101 had never felt more like a living heartbeat. Golden threads of Veldora's infinite pure destruction-and-creation energy pulsed softly through the velvet couches and floating lanterns, turning the space into a warm cocoon of light and laughter. The Primordial Sisters' backstories still lingered in the air like the afterglow of a perfectly timed anime climax—Testarossa's elegant loneliness, Carrera's battle-weary boredom, Ultima's chaotic emptiness—all now wrapped in the same golden glow that made everything feel possible.
Ramiris, never one to let a good moment breathe, zipped to the center of the room like a pink spotlight operator. "Master Veldora! Master Veldora! Your disciple Ramiris declares story time is not over! The fancy butler has been standing there looking all mysterious and elegant the whole time! Diablo, spill the ancient tea! The Great Ramiris wants to know how the perfect servant became the perfect servant!"
She landed on Diablo's shoulder with a dramatic flourish, wings buzzing. "Master! Your infinite energy made the Primordial Sisters open up—now make the butler do the same! Pretty please with gacha rates on top!"
Diablo didn't flinch. He simply raised one gloved finger and gently flicked her off with a courteous energy barrier, sending her tumbling into a floating cushion with a delighted squeal. "Lady Ramiris, while your enthusiasm is… illuminating, one does not simply demand the history of a Primordial. However—" he turned to Rimuru with a deep, formal bow, crimson eyes softening in a way only those who knew him could catch "—if my lord wishes to hear it, I shall share. Master Veldora's gift has made even an old shadow feel… ready."
From the tenth-floor manga fortress, Veldora's deep, scholarly voice rolled across the shared mental link, warm with ancient wisdom yet laced with otaku mischief. "Hah! The tiny queen has once again invoked my title. Probability of this turning into a three-act emotional drama with zero plot armor: 95.1%. I remain here supplying the nation's endless creative and destructive power from my Fortress of Solitude while conducting critical research on the newest Slime Hero Chronicles volume. Takumi, apply the soft-focus filter. Dramatic side-lighting only—no harsh shadows on the butler's tragic past."
Takumi's voice chimed in, casual and full of programmer nostalgia. "On it, Master Dragon Bro. Back when I was alive—seventy-two-hour coding crunch on that isekai VRMMO, zero sleep, energy drinks as my only companions—I stood up screaming 'THAT'S THE GOOD STUFF!' during the hero's final power-up and… bam. Heart attack. Classic karoshi with extra otaku seasoning. Now I'm a Manas turning a demon butler's millennia of waiting into premium flashback material. Infinite energy feed stable at 450%. Cue the emotional BGM."
Rimuru floated closer, tiny slime form glowing with quiet encouragement. "Diablo… only if you want to. We're family. No pressure."
Diablo's smile was small, elegant, and impossibly sincere. He adjusted his white gloves with perfect precision and began, voice smooth as aged velvet. "I was born as Primordial Black—Noir—in the very first fracture of the Underworld's void. While my sisters danced in white light, yellow flame, and purple mischief, I emerged from pure shadow itself. I watched civilizations rise and fall, Demon Lords rise and betray one another, all in the name of fleeting power. I served many—kings, tyrants, would-be gods—but none ever earned my true loyalty. Their ambitions were hollow. Their hearts… unworthy."
Shion sniffled loudly and shoved a glowing onigiri into Diablo's hand before he could protest. "That's so lonely! Here, eat this 'Eternal Wait Relief Onigiri'! Oni-giri, add extra seaweed for dramatic backstory flavor!"
Oni-giri bobbed solemnly. "As you wish, Mistress. Though I suspect the real seasoning is 'found family tears.'"
Testarossa leaned forward, silver hair catching the golden light. "You waited… as we all did. But you waited longer than any of us, brother."
Carrera cracked her knuckles, eyes blazing. "Sounds boring as hell! I'd have punched the unworthy ones into next week!"
Ultima giggled and created a tiny harmless explosion that smelled like strawberries. "I would've pranked them until they cried! But you just… waited? That's hardcore elegant!"
Ramiris zipped back onto the coffee table, striking a pose. "Master Veldora! Your disciple is getting chills! The fancy butler waited thousands of years for a worthy master—and then he found Rimuru! Your infinite energy made this moment possible! Tell us the part where you finally met the slime boss!"
Diablo took a delicate bite of the onigiri—because refusing Shion was never an option—and continued, voice never losing its refined cadence. "Precisely. For eons I wandered the deepest layers, observing, rejecting, waiting. Then I heard of a certain Slime who had devoured a True Dragon's power, built a nation of monsters living in peace, and treated even the lowliest goblin as family. I observed from afar… and for the first time, I felt something stir. Not ambition. Not boredom. Hope. When I finally presented myself, Lord Rimuru accepted me not as a weapon, but as a person. He gave me a name, a purpose, and a home worth protecting. Master Veldora's infinite supply has only deepened that bond—making even an ancient shadow feel truly alive."
Milim bounced on her cushion so hard it nearly flipped. "That's the coolest wait ever! You're like the ultimate final-boss butler who waited for the hero to show up! We should throw a 'Diablo Finally Found His Master' party—with explosions!"
Benimaru's eye twitched, though a reluctant grin tugged at his lips. "You waited millennia for someone like Rimuru… and now you've recruited three more Primordials to serve him. I'm starting to think your patience is scarier than your power."
Rimuru's slime form wobbled with genuine emotion, the brotherly link with Veldora pulsing like a warm, endless river in his core. "Diablo… I had no idea how long you waited. Thank you. For choosing us. For choosing me."
Diablo bowed lower than usual, voice soft with rare vulnerability. "It was never a choice, my lord. You are the first worthy of my everything."
Veldora's chuckle boomed with big-brother pride beneath the otaku layer. "Magnificent. Probability of the butler tearing up in elegant fashion: 12%. Takumi, save that subtle voice crack for the highlight reel. The shut-in dragon rests easy knowing his little brother's most loyal shadow has finally found peace."
Takumi laughed warmly. "He's totally getting misty-eyed in the sanctum—I can tell. I've already sketched Diablo's 'eternal vigil' anime key visual—black cape, dramatic wind, single tear of loyalty. Peak cinema. Welcome to the found-family route, Butler Bro."
Ramiris pumped her tiny fist at the ceiling. "Master Veldora! Your disciple declares this the best backstory yet! The Great Ramiris is making a special 'Eternal Butler Floor' with infinite tea and dramatic waiting rooms! Everyone, group hug the fancy butler!"
The lounge exploded into motion. Ultima and Ramiris tackled Diablo's legs in a chaotic pile. Carrera slapped him on the back hard enough to crack the air. Testarossa placed a graceful hand on his shoulder, smiling softly. Shion shoved more onigiri at everyone while Oni-giri muttered about "emotional calories." Milim demanded a victory pose. Even Benimaru joined the pile with a resigned chuckle.
Rimuru floated into the center of the tangle, feeling the infinite energy threads weave tighter than ever—ancient shadows, primordial power, otaku creativity, and pure family chaos all bound together by Veldora's endless supply.
Diablo allowed the hug for exactly three seconds—because butler dignity—then gently extracted himself with elegant precision, though his eyes shone brighter than usual. "My lord… my family. I am truly home."
Veldora's final transmission carried scholarly warmth and shut-in satisfaction. "Well done, little brother. The supply line flows eternal, turning eternal waits into eternal bonds. I return to my research—episode 51 awaits. But know this: the shut-in dragon is proud. Takumi, extra butter. And prepare the group photo filter."
"You got it, Master Dragon Bro. Backstory archive complete. New party lore unlocked—maximum loyalty stats achieved."
As the group dissolved into laughter and light-hearted bickering—Ultima already planning a "welcome prank" on the new butler, Carrera challenging everyone to arm-wrestling, Testarossa politely declining yet another onigiri—the lounge glowed brighter with golden sparks of creation. The unique dynamics deepened once more: an ancient butler who had waited through eternity finally surrounded by the family he had always sought, all thanks to a slime, a shut-in dragon, and an otaku Manas who turned loneliness into laughter.
Outside the Dungeon, the winds of Tempest carried soft golden threads, the scent of fresh onigiri, and the quiet, elegant heartbeat of one butler who had finally stopped waiting.
