Synopsis
Makoto Kubota coasted through life without taking anything too seriously or examining his own inner self too closely. As the leader of a youth gang under the Izumo Group, he kept himself occupied with yakuza skirmishes, mahjong, and assassinations—until the day he happened upon a mysterious substance called Wild Adapter, a drug with bizarre side effects including death. Forever changed by the encounter, Kubota becomes involved with a wandering man named Minoru Tokito, and the two develop an unusual partnership that pulls them deeper and deeper into the enigma of Wild Adapter.
