An arrogant perfectionist, Tobio is referred to as 'King of the Court', a derogatory nickname that satirizes his egocentric attitude, given by his former teammates at Kitagawa Daiichi. He is actually much more sensitive & childish than he looks, doesn't know how to control frustration, expresses his thoughts & emotions in a proper way. He grows to respect his seniors more, accepts people whose abilities/views are different from his own, understands the importance of teamwork and mutual trust.
