Kou manages a small shop in the Chinese area of Yokohama. He acts as Tokitou's doctor ("veterinarian"), despite the fact that he is unlicensed.

Kou sells various questionable odd and ends in his shop, including weapons and drugs and is good at getting information. He employs Kubota for odd jobs like deliveries.

Makoto Kubota wandered through life, not taking things too seriously or looking too deep within himself. His job as the head of the Izumo Group's youth gang kept him pleasantly occupied with yakuza wars, mahjong and assassinations... Until the day he stumbled upon a strange drug called Wild Adapter that produces bizarre side-effects--including death. Forever changed, Kubota becomes entangled with a drifter named Minoru Tokito, and the two form an unlikely companionship that draws them deeper into the mystery of Wild Adapter...<br><br>
