He was born and raised in Kabuki district. Ever since he was a child, Jirochou would get into fights and start trouble, but Otose would always be there to straighten him out, as they were childhood friends. Even after he got into organized crime, Otose was the only one who stood by him and tried to set him straight. As a result, Jirochou became a vigilante who was popular enough to be considered a leader of the town. They say without Otose, Jirochou wouldn't be the man amongst men. Nobody could defeat him in a fight, except for Terada Tatsugorou.
