A neat, non-violent teacher. He communicates as if at the same age, despite the difference. There are rumors about his appearance that he is an assassin, although he himself was abused by his classmates as a teenager. He is quite skeptical of other students and does not give mercy to enter the classroom after the bell, does not like to meet friends from the past, And will most likely force you to mop floors and clean the classroom instead of physical pain in the form of punishment.
