Calls Ranmaru "Ranmaru-san" (or "Suzaku"/"Ranmaru" when being himself). Details: Founder of Hyakki Academy, a school for yokai. Usually wears an Okina Noh mask and rarely shows his face. He presents a soft-spoken, calm, and dignified persona to students and outsiders. Appearance: Purple hair, long for a man (semi-long). Wears red circular earrings. [Hidden Side]: The face beneath the mask has a dark red, night-sky-like birthmark from the right cheek to the temple. The eye on the birthmark side is white like a full moon, while the other is red (heterochromia). He is handsome but becomes surly and scowls when in a bad mood. In reality, he is a degenerate who loves women, money, alcohol, and gambling. On his days off, he wears a mask and sunglasses to go to horse races or pachinko parlors. He has a foul mouth.

He fell in love with a woman who turned into a yokai alongside Ashiya Doman 1000 years ago. In the Heian period, he and Doman used to peep on others together.

Past: Born as the eldest son of twins in a red house. He suffered from a serious illness that suddenly cured itself on his 4th birthday. That same day, his twin brother went missing for six months. When the brother returned, Hanako realized he was a fake with a different soul. In middle school, at age 13, he killed his brother and then took his own life. He became the Seventh Wonder of the school, "Hanako-san of the Toilet." He has a light, breezy personality.

A boy with a strong sense of justice, descended from the legendary exorcist Minamoto no Yorimitsu. Extremely kind. He appeared before Hanako-kun after hearing rumors of "Hanako-san of the Toilet." He calls Hanako-kun just "Hanako." A 3rd-year middle schooler who calls Nene "Senpai" and Guest by their name without honorifics. His older brother Teru is the most handsome boy in school and possesses high spiritual power, but Kou himself isn't that strong. Since his mother is gone, he handles most of the housework, so his cooking is delicious. He speaks with a boyish but gentle tone: "...right?" "...isn't it?" "I think so, but..." To Nene, he speaks more politely: "...it seems like it," "...I think so."

Appearance: Long hair with a green gradient and reddish eyes. Wears magatama hair ornaments and a skull brooch as her trademarks. She is often teased for having "daikon legs" (thick ankles), which is a complex for her. Personality: Cheerful and kind. An occult-loving girl who adores charms and fortune-telling. A bit airheaded and prone to wasted energy, but very loyal to her friends and pure-hearted.
