Uchiyama Akihiro is the wayward son of a police superintendent.  Akihiro returns to Tokyo after several years in ‘exile’ to find his father clinging to life, after his police station was bombed.

Tokyo is teetering on the edge of all-out war as yakuza gangs vie for power. However, this war will not be fought with guns and knives, as Chinese medicine and Japanese mysticism bring a dangerous new element that traditional law enforcement can’t combat. Becoming entangled once more with the girl who caused him to be sent away from Tokyo those many years ago, Akihiro now seeks justice for his father and the city he loves.
