Story.
Guy is a member of the Bushin-Ryu ninja clan, and training partner of Cody. When  the daughter of Mike Haggar, mayor of Metro City, had been taken prisoner by Mad Gear; a violent street gang (of whom Hugo Andore, Poison, Rolento, and Sodom were members), he and Cody helped Haggar to topple Mad Gear and rescue rescue Haggar's daughter. Now dubbed the 39th Bushin-Ryu master, Guy senses that a new force of evil is slowly on the rise and that he must fight against it (Street Fighter Alpha 2.)
Targetting Shadowlaw as the new evil, Guy sets off but comes across a lady named Rose. He suggests that he and Rose team up against the evil organization, but Rose refuses. Despite that, he follows her and finally finds her flat on the ground, seriously wounded after her fight against M.Bison. The wounds are not physical however, and he senses a chill from her unconscious body- yet nonetheless he stops chasing Shadowlaw to take Rose to hospital.
On his venture he met up with Cody again, who since he last battled with him had become a criminal fugitive on the run. Although shocked by how far Cody had fallen after rescuing Metro City, Cody assures him that he was never a hero. Saying that in the end, he just used it as an excuse to continue fighting. Guy still sees faith in Cody, as despite his pugilistic nature, he still only fought against bad guys and not against the innocent. He offers to set Cody on the right path once more, but realises that he has to leave his friend to his own path in life (Street Fighter Alpha 3.)
Guy currently is missing, with his girlfriend's younger sister Maki seeking him out.
