OVERVIEW OF IT ALL:
Sera Slice is the main protagonist
Sera is more down-on-her-luck financially--her family wanted her to be a hero, but she had to work a job to help support them, so she wasn't able to train up her quirk properly enough to pass stuff. her quirk IS still strong, but not good enough to beat the various exams, nor notable enough for any heroes to take her under their wing
so, Sera does more petty crimes, trying to pay off everything she can

two heroes, Korpse and Chamber, are here to stop her. Korpse is more of a rookie hero, while Chamber is an established one

Korpse is someone who believes himself to be an edgelord, but is actually more of a helpful, almost cinnamon bun-like character. his quirk, Dental Record, lets him create duplicates of the skeletons of anyone, provided he is able to get a copy of any of their teeth. he wears a skull-like helmet with special glasses, which let him take screenshots; he's always looking at his opponent's mouth, trying to get it at multiple angles to study their teeth. when he has enough, he inputs the information into a device, which spits out a few copies.
in case his machine doesn't work, Korpse is able to imprint the knowledge of how a tooth is by touching it, and then can create that with his bone-making power. essentially, his power is to "Expand Bones", creating new bones from old ones--and teeth are both the most easily accessible bone, as well as the one he cares about a lot, because Korpse cares a LOT about dental hygiene. his mother was a dentist.

Chamber is a loose, wise-cracking woman who always appears at ease. she can be hard-boiled if the situation calls for it, but only shows the serious side of herself if she believes she has to.
her quirk, Bullet Self, lets her swap places with any projectile she fires--usually this is with rubber bullets she packs her gun with, but she can also throw things and swap with those, too.

SCENE:
Sera's family is getting into deeper debt than before; her father's debt by the Yakuza was finally brought up today, and they need to pony up a LOT of money, pronto, or else Chisaki will splatter the whole family into blood. so, today Sera has decided to rob a bank--in the past, she's just gone for convenience stores and such, but this time she's going for an entire bank vault, as that's about as much as they owe.
