Taiga has somewhat of a rash nature that is commonly described as yankee (ヤンキー lit delinquent) and is often called as such by Kakeru Juuouin. The only person who can seem to control his rebellious behavior is Minato Takahashi. He often has a bored expression on his face and rarely speaks. On the surface, Taiga is a bit stubborn and self-centered, not caring about other people's business as long as it doesn't concern him.
