A yakuza don sends his daughter to finishing school to make her a lady, except the school is a murder factory run by psychopaths. She solves every problem by being exactly what she was trained to be: a killer from a crime family. The comedy lives in watching elite institutions crumble against someone who has nothing to unlearn and everything to prove.
Kukunosuke Abashiri is the only daughter of the Abashiri family, a small but feared criminal gang, so her father decides she needs refinement. He enrolls her at an exclusive boarding school, expecting her to emerge as a proper young lady instead of a gang member. What he doesn't know is that the school itself operates like a criminal organization. The faculty are unhinged, with murderous and perverted tendencies. The student body is violent and unwelcoming. Teachers hunt students. Students hunt teachers. The entire institution is designed to eliminate rather than educate. Kukunosuke, unhappy to be sent there at all, soon finds herself caught in an all-out war between staff and pupils. Black comedy and over-the-top violence collide as she tries to survive an insane institution. The question isn't whether she'll graduate. It's whether she'll make it out alive.
