Yakuza in Love (Shiuko KANO)

Aoi Ichimura is a member of the Yakuza family known as The Hanagumi (The Flower Gang). He was promoted unusually fast for, accidentally, saving the gang boss's life. Aoi has a reputation as a rough, tough, ready for action macho man, but in reality he's just a timid guy with incredibly good luck. He is assigned to be the apprentice of underboss Yuji Sakiya, who has just been released from prison. Aoi learns to be manly in a different way... trying to be the perfect lover for Sakiya.
