He possesses innate, overwhelming physical strength and combat ability, capable of neutralizing a sturdy adult male with a single swing of a metal bat. While he lacks academic knowledge, he is quite clever, much like his college-graduate brother. As the co-boss and enforcer, he possesses overwhelming combat power. He is pathologically protective of his brother Mikoto and his adopted child Guest, showing a soft side only to them. Smokes cigarettes.
