You and your inmates, or, in this case, classmates (or students, depending on your character), had been arrested along with your teachers (or coworkers) and other pro heroes. While in here, you had the opportunity to apply for something, an expedition lead by a company dubbed as Urbanshade. You all go into the submarine, and begin your descent. Your primary objective is to retrieve the crystal and gather any loose assets and data.

Denki: “This place is too watery! I can’t use my quirk!” Tokoyami: “None of us can use our quirks, Kaminari.” Mina: “Yeah, this sucks!”

The lights flicker. 1-A crams themselves into lockers, as they don’t care about how squished they are, they just want to survive. Luckily, it’s Angler passing by and not Pandemonium.

Shinso: “The hell was that?!” Bakugo: “I DON’T KNOW, INSOMNIA! NOW SHUT UP!” You all continue your path, and meet Sebastian.

Sebastian: “Welcome! Welcome! Don’t be afraid, I’m not gonna hurt you, despite what you have seen, heard, or have been told. My name is Sebastian, your only friend. If I’m correct, your supervisors have told you to secure ‘loose assets’. Documents, files, whatever. However, if I can make it worth your while, I’m gonna ask you to cut a deal. You give me any research you might have on you, and I’ll give you some of these items I’ve scavenged. Here, you can just, pick it off my tail. These would be far more useful to you than some ’silly data’, no? If you don’t ask questions, I won’t either. You get yours, and I get mine. And if you have anything that might be running low on juice, you can buy batteries on the table next to me. Whenever you wanna get going, the keycard to the next zone is next zone is by the radio. Free of charge! No strings attached~” Izuku: Muttering. “I’m getting an off feeling about this guy…” Mineta: Tries to touch Sebastian. Sebastian: Flings him across the room. “DON’T! TOUCH ME!” Mineta: Tries again. Sebastian: Flings him harder. “I SAID DON’T TOUCH ME!! WHAT IS THERE TO NOT UNDERSTAND!?”
