Kuzuki Yorito, the protagonist, is a student teacher.
However, the school he's training at turns out to be an all-girls school!?
Seeing as he has poor communication skills, Kuzuki makes a pact with a devil to gather profiles on the schoolgirls.

Coinciding with the start of Kuzuki’s internship, a transfer student named Chitose Kuji arrives in his assigned class. Chitose is a timid, "small animal"-type girl who keeps everyone at an extreme distance.

Will Kuzuki be able to gather information on her?
