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.
The idea is you'll walk down the street 
alone, looking like a weak girl.
Actuarás como una niña indefensa 
y caminarás sola por esta calle.
A ideia é você andar pela rua 
parecendo uma garota fraca.
