Charisma
Shinichiro had an unrivaled charisma. During his youth and many years later, his name remained widely known among the criminals. He was able to inspire others due to his ability to stand up for others, as well as his impressive humility despite his fame. Due to these traits, Shinichiro was respected by everyone, and his leadership was looked upon favorably. Despite being a very weak fighter, he was able to lead not only the Black Dragon, but also the unofficial world of criminals, as even rival gangs respected him.

Shinichiro had short, messy hair that matched his dull black eyes. He was slim, tall, and had a heart-shaped face, much like his younger brother, Manjiro Sano. He had thin lips and smoked cigarettes frequently. Despite running a motorcycle repair shop, he was never seen in a uniform and preferred to wear casual clothes. Shinichiro wore a pearl-white shirt, light-colored jeans, and comfortable shoes. He sometimes wore a jacket while working, wrapping it around his waist. He rarely wore accessories, but Shinichiro did have a silver chain around his neck.

As a delinquent in his teenage years, Shinichiro had a neat pompadour hairstyle and wore the traditional Black Dragon uniform.
