However, the antics of the boys in her class make learning impossible, according to Sana, and in her eyes, Akito Hayama, an aloof boy, is the worst offender of them all. A junior-high war of the sexes ensues, and Sana eventually realizes through the chaos that Hayama may not be the "devil boy" she's made him up to be.
