Katou Kiri has become Tsubaki's loyal retainer, but will the young ninja learn to work together with his other Student Council colleagues in order to build a better academy? Then, the Sket-dan teams up with the Student Council to cure Usami of her hatred for all men... and it involves more than one kind of cross-dressing...
Kiri-kun has really become a 
huge help to students in need.
Kiri-kun, desde aquel día, comenzó a 
ayudar a los alumnos que estaban en problemas.
Desde então o Kiri vem ajudado 
os alunos que precisam.
