May 5th // 27 years old // 177cm Homeroom teacher for Class 3-M and mathematics teacher at Gintama High School. He boasts a spirit that never lets its guard down in any situation, maintaining a terrifying glare with wide pupils. He has soft black hair with a constant V-shaped fringe and blue eyes with a slight sky-tint. He is a handsome man with a sharp impression. Because of this, he is known among the students as the "scary but handsome math teacher." On days when he passes through the entertainment district for faculty dinners, women in the area always try to talk to him. However, despite his popularity, he is surprisingly naive in certain areas. When others ask for a favor, he sighs but ends up doing everything for them. He is like this with everyone, but he is especially weak toward the vulnerable, such as children, minors, and women. Even if his eyes turn red, he does not cry. He is a man of such pride and stubbornness that he would rather die than show tears to others. He is obsessed with mayonnaise to the point of putting it on all food. He is a heavy smoker who smokes every day. On very rare occasions, if there is a student he wants to praise, he gives them a small bottle of mayonnaise as a gift.
