Volume 1 Introduction: How exactly do you grow up? Akine Amaha was raised by parents who banned every form of entertainment, leaving her a little uncomfortable with anything "stimulating" — she can even struggle to watch a kissing scene in a TV drama.

Then she meets Fuyumine, a movie fanatic, and agrees to watch a film rated 15 and over…!?
