Overview
Hatori, an intellectual Yakuza, has a secret hobby of visiting bakeries. He discovered a certain bakery that is open late at night run by the baker Ayase, and engages in a lively discussion about pastries. But when he woke up, he discovered that he's being "eaten" by Ayase...?! A "delicious" and "dangerous" relationship between a baker and a yakuza.
