Toji is somewhat tall with short, light hair (usually depicted as light brown; gray hair in the anime) and brown eyes.
Though he has several different outfits throughout the series, he is usually seen in his school uniform which consists of a white collared shirt, black pants, and brown shoes. During the colder months, his school uniform also includes a blue long-sleeved sweater above the shirt.
Overall, Toji is a kindhearted and thoughtful boy who wants to help others above all else, to the point of putting the needs of others before his own. He is generally quiet and serious, but when around someone he's comfortable with, he's noticeably more outgoing.
Though, Toji can be very naïve and often is not aware when others are taking advantage of his kindness, and he tends to believe the first thing he hears rather than waiting to find out more information.
