Tarô Itsumi

In the world of the Ninja, fighting skills play a small role in one's rank in the Shinobi order. Kageru is the best in his class, but his birth predestines him to the lower class. His friend Aoi is dealt the same fate; together they'll have to question themselves.

Detective Nishi is relieved from a stakeout to visit his sick wife in hospital. He is informed that she is terminally ill, and is advised to take her home. During his visit, a suspect shoots one detective dead and leaves Nishi's partner, Horibe, paralyzed. Nishi leaves the police force to spend time with his wife at home, and must find a way to pay off his debts to the yakuza.
