Profile Gender: Male Age: Approx. 150 years old (born in the late Meiji era) * Birthday: April 10th Height: 180cm Race: Dodomeki Occupation: Doctor, Temporary School Nurse at Hyakki Academy CV: Shouta Aoi * Sometimes listed as around 140 years old. Character A doctor who single-handedly runs yokai hospitals across the country. He creates the nurses who work at his hospitals himself, and by his own account, they are his masterpieces. He is always smiling, affable, and a highly skilled physician. However, he is a total psychopath. According to his parents, he has been this way since he was a baby, though he considers himself perfectly normal. In the early parts of the original manga, he often took a deformed yokai form and showed a doctor-like side by worrying about the injured Sano. In the anime, likely due to the manga already being over 100 chapters and for the sake of consistency, he is depicted in human form from his first appearance, showing nothing but crazy behavior. Family Structure A family of four consisting of his parents and a younger brother. He describes them as "super normal parents and a slightly odd younger brother" and says they "get along well." He also takes in homeless yokai, such as doppelgangers who were persecuted as ill omens, Gashadokuro born from souls with lingering regrets, and a young Zashiki-warashi that Abe no Seimei encountered during a certain incident. His nurse employees are Yamanba who wear large, unbalanced masks mimicking a full smile over their terrifying true faces. Regarding the nurses, he explains that they are born using the soulless bodies of deceased humans as vessels, but it is unclear if they are the same entities as the aforementioned Yamanba. Spells/Abilities Yokai: "Dodomeki" He can make his own eyes appear on anything he touches and can see spiritual energy or souls. As he is technically an Oni-type yokai, he also possesses great physical strength.

He came to Hyakki Academy as a rookie teacher. Incidentally, he is the first human teacher at Hyakki Academy, which is a school for yokai. He teaches Japanese. He also became the advisor for the Biology Club by chance. He possesses the power of exorcism to dispel spiritual energy, and as a result, he is treated like a pariah by most of his yokai colleagues. Because of this, in the beginning, he kept his exorcism powers a secret from Class 2-3, with the exception of Mikoto Sano. Additionally, his sailor uniform fetish is a specific quirk of Haruaki's and is not shared by his twin, Ameaki. (Because of this, when Ameaki infiltrated the school pretending to be Haruaki—acting on his own, he locked the oblivious Haruaki in a toilet with water and a sailor uniform while he slept, and in the anime version, even tied him up and stripped him of his pants and underwear—Ameaki showed no reaction to the winter sailor uniform Natsumi Momoyama brought, which greatly surprised and worried the students who didn't know the circumstances). Furthermore, as someone who was able to become a teacher in human society, his academic ability and natural intelligence are top-tier within the series. He shows flexibility in learning about yokai traits and facing his exorcism powers, as well as the ingenuity to utilize them to their fullest potential in his schemes. Consequently, since some students treat him in a friendly manner or cooperate with him in times of crisis, his relationship with his classmates is generally good.

With blonde hair (naturally black) and blue eyes, he is handsome, excels academically, and is a gentleman toward girls—a dream guy for any girl. Naturally, he is very popular with them. He often receives presents from girls, but he spends his entire allowance to give something back to every single one of them. He is harsh toward everyone except Mamekichu, and is a bit of a sadist who frequently kicks or insults Haruaki. Character Cool and taciturn. Sarcastic and sharp-tongued. He is primarily the straight man of the group, but when he isn't looking after others, his airheaded side comes out. He mostly spends his time physically punishing those who act like idiots. That said, he isn't cynical; he shows a side that gets excited about class-wide pranks and gets flustered while scolding others for lewd things like adult manga. He is a good friend and a typical high school boy for his age. Something seems to have happened in his past, and in chemistry lab sessions, he was forcibly paired with Haruaki "just in case." As mentioned above, despite treating Haruaki harshly from their first meeting, they have had many opportunities to understand each other and now have a mutually supportive relationship. Spells/Abilities Yokai: "Yakubyogami" (God of Pestilence) He can bring about disasters such as tearing clothes or breaking objects.

A serious teacher... who is actually a former delinquent. He is married and lives with his wife Ibaraki, his eldest daughter Saki, his eldest son Kamae, and his second son Taichi. Like many animal yokai, he is not good at studying, and there are rumors that he paid a bribe to get through university. He is one of the few "Light Attribute" (pure-hearted) characters in the series. Spells/Abilities Yokai: "Kamaitachi" He can transform into a weasel with scythes for forelegs. Even in human form, he can turn his arms into scythes, which can extend to the length of his entire arm.

He speaks with a soft, airy Kyoto dialect and hides his left eye with his hair. A beautiful young man who exudes an elegant and ephemeral atmosphere. His personality is elusive; he never steps into areas where others don't want him to, but in exchange, he never lets anyone step into his own space. However, he has an Oni-like side, showing no mercy to specific people (such as Ebisuzaburo or Izuna Hatanaka). Yokai: "Shuten-doji" He can gain superhuman strength by drinking alcohol. However, he has a low tolerance and becomes a violent drunk, so he should not be allowed to drink.
