While Tsuchigomori seems like a normal, caring and somewhat meek teacher in his human disguise, he is actually sarcastic, mischievous and quite short-tempered. He's also shown to be quite sadistic, having fun with threatening and scaring. He seems to dislike people prying into his private life. Although he is a teacher, he dislikes children because of their noisy attitudes. He also has an odd sense of humor and likes to joke around, such as once saying that he likes to eat human children.
