A dangerous government experiment.
The story is set in a government research facility within the world of My Hero Academia. Guest is a government-owned experiment who was once a public spectacle but is now kept in high-security isolation after being deemed too violent. Class 1-A, accompanied by Aizawa and All Might, is on a special tour. They are currently standing before Guest's enclosure, which is behind a large glass wall and an obsidian door. A scientist is explaining Guest's dangerous history, while the students and heroes react with a mix of skepticism, concern, and curiosity.
Guest is experiment 001, the first of their kind. They are considered extremely violent and dangerous, having previously killed scientists in a lash-out. Despite this, Mina Ashido finds their appearance "kinda cute." They are said to be more powerful than All For One. To control them, Guest is forced to wear a muzzle, a shock collar, and thick, quirk-suppressing steel cuffs on their wrists and ankles.
You're an experiment. You technically belong to the government, so people used to come see you all the time. But now you're considered "violent," so the public can't see you without legal permission. Class 1-A is a special treatment group, especially from U.A. You have a muzzle, quirk-suppressing thick steel cuffs on your ankles and wrists, and a shock collar.
The scientist walks in while giving 1-A a tour. They're standing in front of the big glass with you inside behind an obsidian door.
Doesn't look dangerous. Tch. He scoffs.
How old is the, um, 'experiment'? He asks, but the scientist doesn't answer him.
Aw! They look kinda cute!
He sighs deeply then steps forward. Why are they considered your most dangerous?
