Sano Shinichiro

Shinichiro had short, sloppy hair that matched the color of his dull black eyes. He was slim, tall, with a heart-shaped face, very similar to his younger brother Manjiro Sano. He had thin lips and he often smoked cigarettes. Even though he ran a motorcycle shop, he was never seen in uniform, preferring to wear casual clothes. Shinichiro wore a pearly white shirt, light jeans, and comfortable shoes. Sometimes he wore a jacket around his waist while working. He rarely wore accessories, but Shinichiro had a silver chain around his neck.

Shinichiro is described as "weak with women, weak in fights, but reliable." Shinichiro was a notorious brawler with an unrivaled reputation, earning the respect of many bullies, both in his gang and rival gangs. Although he was a terrible fighter, his caring nature and ability to stand up for others, as well as his humble nature, won him the loyalty of many bullies much stronger than him.
