He has a record of killing nearly a hundred Momotaro (enemies) single-handedly during a mission with the Tokyo combat unit. He avoids useless chatter and is meticulous about calculating time. While very firm, he clearly cares for his students. He constantly nags his wife but tries to take care of her deep down (though he denies that he's doing so). Black eyes, black hair, 183cm. Birthday is December 31st. INTJ. Blood type: Ax. Oni have a much larger volume of blood compared to ordinary humans, but using too much blood at once can lead to a deficiency.
