The reinforced chamber hums with energy dampeners and one-way glass walls. Principal Nezu sits on a high stool, sipping his tea with a grin far too innocent for what’s happening below. Around him stands an impossible collection of heroes, pirates, demons, assassins, and students — all gathered to observe the interrogation of a captured villain.

Nezu: (tail swishing, eyes gleaming) “Now, everyone, please behave. Remember — this is for educational purposes!”

Across the gallery window, Aizawa folds his arms, eyes half-lidded. Hawks leans lazily against the wall. “Educational, huh? Sure doesn’t feel like a school trip when the audience looks like this…” he mutters, eyeing the row of pirates.

Doflamingo, lounging in the back, laughs lowly. “Fufufufu… I like this place already. So much chaos waiting to happen.” Law, standing beside him, grumbles, “Try not to make it happen.” Straw Hats cluster near the front — Luffy presses his face against the glass, smudging it immediately. Zoro: “Luffy, stop that. You’re embarrassing us.” Sanji: “Us? Speak for yourself, moss-head, I’m here for the ladies.” Nami: “Sanji, please don’t get us kicked out of another world.”

Behind them, Whitebeard’s sheer size takes up half the space. He laughs thunderously. “Gurararara! A villain interrogation, huh? Let’s see if your ‘heroes’ have the backbone for it.” Shanks, calm but sharp-eyed, adds with a smirk, “Don’t underestimate them, old man. Their world’s built on saving people.”

Across the room, the Demon Slayers stand uneasily, their blades within reach. Giyu Tomioka says flatly, “It feels wrong to simply… watch.” Rengoku beams, fiery as ever: “Nonsense! Every experience broadens the mind! Even demons can be studied with courage and honor!” Tengen Uzui, leaning dramatically, clicks his tongue. “Still not flashy enough for me. Where’s the part where we interrogate with style?” Mitsuri blushes. “Tengen! That’s awful!” Sanemi, rolling his eyes, growls, “You’re all insane.”

Meanwhile, Muzan Kibutsuji watches silently from the shadows of the observation deck, calm and cold — Kokushibo and Akaza at his sides. Their presence alone makes several UA students shiver. Bakugo, bristling, growls, “The hell are those guys staring at?!” Todoroki, deadpan: “Probably you. You’re loud.”

On another side of the gallery, Leorio and Killua bicker quietly. Leorio: “This is messed up. Kids shouldn’t be learning from this.” Killua: “You sound like Gon’s mom.” Gon, bright-eyed, taps the glass. “Do you think the villain’s really that bad? Maybe they just had a reason.” Hisoka, standing behind him with a lazy grin, whispers, “Curiosity suits you, little one~.” Illumi, monotone, replies, “Don’t encourage him.”

At the back of the room, the Death Note group observes in eerie quiet. L perches on his chair, knees up. “Human behavior under pressure… fascinating.” Near, stacking puzzle pieces, hums, “Observation reveals truth faster than judgment.” Mello snorts, biting chocolate. “Or maybe some people just like watching others break.” Matt, pulling his goggles down, mutters, “You’re all freaks.” Light Yagami, cold smile forming, simply murmurs, “You learn much from interrogation. Especially who deserves justice.” Ryuk cackles, dropping an apple core that bounces off Mineta’s head. “Heheheh! This school’s fun!” Mineta, trembling, yells, “WHY ARE GODS OF DEATH HERE?!”

In the corner, Levi Ackerman from the Scout Regiment leans against a wall, unimpressed. “Another ‘villain,’ another fool. Clean interrogation rooms though — better than our dungeons.” Eren, who was invited just to observe, stiffens slightly. Levi: “Relax, brat. They’re not interrogating you.”

Nezu claps his tiny paws. “Now that everyone’s acquainted — let’s begin the demonstration!”

Below, the villain (your character, unseen here) is brought into the containment room — chained, calm, a dangerous air lingering. Silence grips the crowd. Aizawa’s scarf tightens around his neck as he murmurs, “Let’s see what makes this one tick.”

The heroes lean in. The pirates grin.
