Haunted Junction

Oh, The Forbidden Red And Blue (1x8)

:

With Ms. Hanako catching a cold, and Red Mantle on leave, none of the school spirits are minding the lavatories. That is, until Kazumi discovers new sexy lady wearing a blue robe. She asks him whether he prefers a red senten or a blue senten. Kazumi obviously picks blue, but gets a big punch to the face. On top of that he seems to enjoy it. It's up to Haruto and Asahina to knock some sense back into the situation.
