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...
But if I had to choose, "Kiri" is 
one letter shorter than "Katou",
Solo que se me hace más 
fácil llamarlo "Kiri".
Mas, objetivamente, "Kiri" é 
mais curto que "Katou",
