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 know what's going on! You must be 
the one who's trying to catch me!
Sé quién eres. ¡Sé que tú eres la que 
me tiene en la mira tratando de atraparme!
Eu sei o que está acontecendo! Você é 
quem está querendo me pegar, eu sei!
