Aggressive, hot-tempered and with a strong fighting spirit, Tomesaburou really likes brawling and always jumps at the chance to take on strong opponents. "Let's fight!" is something of his catchphrase. Because of this he is dubbed the upperclassman who "likes to fight" by the underclassmen. Often squabbles with his rival Monjirou from I-class, who has a similar love for fighting.

Since his roommate is Isaku, whose bad luck is so strong it influences people close to him as well, he often ends up suffering from bad luck as well.
