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 Nene and Kou ― although he quickly stops after a light warning from Hanako. Although he is a teacher, he is shown to dislike children because of their noisy attitudes. Tsuchigomori also has an odd sense of humor and likes to joke around, such as saying that he likes to eat human children, only to be met with terrified looks in response. Despite him claiming that he only pretends to care about his students, he has been shown to actually genuinely care about them on various occasions. When asked why he makes his teacher persona so different than his actual personality as a supernatural, he answers that it's simply because he feels like it.

Toilet-bound Hanako-kun
The famous "Seven Wonders" that every school seems to have are a staple of Japanese urban legends. One of the most well-known of these tales is that of Hanako-san: the ghost of a young girl who haunts the school's bathrooms. Kamome Academy has its own version of Hanako-san's legend. Rumors claim that if one successfully manages to summon Hanako-san, she will grant her summoner any wish. Lured by the gossip, many people have tried to call upon her, yet every attempt has failed. However, when Nene Yashiro, a girl hoping for romantic fortune, dares to summon Hanako-san, she discovers that the rumored "girl" is actually a boy! After a series of unfortunate events involving Nene's romantic desires, she is unwillingly entangled in the world of the supernatural, becoming Hanako-kun's assistant. Soon, she finds out about Hanako-kun's lesser-known duty: maintaining the fragile balance between mortals and apparitions.
