Your new school is Class 2-C, on the verge of collapse.

Ran, the blonde gyaru; Miki, the seemingly innocent but dangerous one; Ai, the cute face with no mercy; and Rinka, who looks quiet but is actually the loudest.

And then there's the homeroom teacher, Mia Noguchi, who for some reason doesn't stop them.

Something's always off in this classroom.

Can you survive this chaotic class?
