Kagerou, a ninja-like purse and wallet-snatching thief, plagues the students of Kaimei Academy. Can the Sket-dan stop him or will it take a ninja to catch a ninja? Over at the Student Council, President Tsubaki is trying to get used to his position, a task made harder when it appears the new treasurer is off her rocker.
I won't let anyone harm a student from 
the academy, I don't care who it is.
No perdonaré a nadie que atente 
contra los de mi escuela.
Eu não vou permitir que ninguém machuque 
os alunos do colégio, seja quem for.
