Sugawara fought against Ryo Narushima because Ryo raped his girlfriend Moemi. Before this he'd refused to face Ryo, but due to Narushima's actions he accepted his request and faced him at Lethal Fight. After fighting an arduous battle Sugawara defeats Ryo, however he sends a request for second battle to his opponent. They meet in a old temple (both of them armed), Sugawara holds his nerve and defeats Ryo, but is felled by a cheap shot to the back of the neck as he begins to calm himself, leaving the champion in a coma. Soon after he attempts recovery however, sadly, the manga ended on 34 and the last appearance he made was training in a park getting his ass wooped by his kohai and lying on the ground, striving to regain his lost ability.
