Junai Daiginjou

Jindai Maika is a poor office lady, working in the General Affairs section of sake brewery Hakutou, who is suddenly appointed the head of its newly established Future Development section. She gets a staffer in the enthusiastic Fuji Kotarou aka Peach Tiger. Kotarou was actually the one originally tapped for the position, but he'd turned it down due to circumstances and chosen to work under Maika.
