Toji Zenin is a tall, muscular man with a powerful, athletic build, a result of years of physical training. His sharp, cold eyes give off an intimidating, calculating aura, while his presence is both commanding and detached. He moves with an efficient, predatory grace.

Personality-wise, Toji is cold, pragmatic, and often indifferent to others. He shows no interest in the traditions or expectations of the Zenin Clan, preferring his own path.
