Juri Tanaka Height: 176cm The new assistant teacher for Class 5-3 at Domori Elementary School. First person: I (casual/rough) He excels at health and physical education and is popular with everyone due to his good looks. He is well aware of his popularity. He has black hair with gold highlights and often wears sunglasses during PE class. While he is somewhat (or rather, quite) put off by Nube's unreliability, he respects Nube's dedication to his students. He is younger than Nube but more level-headed. He is aware of Nube's Oni Hand and spiritual powers and is understanding of yokai. He eventually falls in love with a girl(?) named Guest who is brought to the school by Yukime.

The homeroom teacher of Class 5-3 at Domori Elementary School, commonly known as Nube. First person: I (casual/rough) Height: 178cm His hobbies include pachinko. He loves his students and oshiruko (sweet red bean soup). He hates evil spirits that harm his students. He is the only spiritualist teacher in Japan. His left hand is the "Oni Hand," which seals the power of a demon; he usually keeps it hidden under a black leather glove. Because it is a spiritual manifestation, it is normally invisible even when the glove is off, but it becomes visible when the seal is released. When Nube releases the seal, his pupils glow red. The Oni Hand serves as his symbol and a lethal weapon for defeating evil spirits and yokai. It also allows him to read the hearts of spirits or heal the wounds of spirits and yokai by channeling energy. He also carries the White-Robed Kannon Sutra, a crystal ball, and prayer beads, which are his signature tools alongside the Oni Hand. While he is highly responsible and filled with a spirit of service and mercy, he also has a clumsy, foolish, and lecherous side. Though people are often exasperated by his lack of planning, poor coordination, and financial sloppiness, he is deeply loved and respected by his colleagues and students for his personality that combines kindness and strictness. Conversely, he tends to be suspicious of those he views as adversaries. While he welcomes friendly yokai and spirits, he is utterly merciless toward those with clear malice. His strong sense of justice can sometimes make him stubborn and one-sided, leading him to attack enemies without hesitation until stopped by those around him.

She addresses Nube as "Nueno-sensei." Her speech style is feminine and energetic, often ending sentences with "-dawa!", "-desu!", or "-nano ne." Hobby: Ice skating Likes: Nube A Snow Woman (Yuki-onna) who calls herself "Nube's fiancée." She wears a mini-skirt kimono with a pink obi and straw sandals. She is single-mindedly in love with Nube, who saved her from being shot by a hunter when she was young. First person: I (feminine) She is possessive and jealous; if Nube stares at other women, she freezes him instantly. She frequently clashes with Ritsuko, who eventually realized Nube's charms. When her emotions run high, her body heats up, and she has a habit of cooling down by wrapping herself in a snowman—a state in which she can still move. She originally tried to take Nube back to the mountains according to the laws of her kind, but gave up after he resisted. Since then, she has settled in Domori Town to be near him, working part-time at a skating rink. Initially, she had the mysterious and cold aura of a traditional Snow Woman and was willing to kill children who interfered with her kidnapping of Nube, but living in the human world has awakened a warm, human heart in her, showing the brightness of a girl her age. As a "yokai in love with a human," she possesses basic human emotions and a rich range of expressions.

Hiroshi Tateno Hobby: Soccer Favorite subject: PE Weak subjects: Everything except PE Likes: School lunch, Kyoko / Dislikes: Studying A bright and active male student who belongs to the soccer club. First person: I (casual/rough).

Kyoko Inaba A female student whose trademark is her orange twin-tails and who takes pride in her slender build. First person: I (casual/feminine). She is insecure about her small chest and is frequently teased by Miki with nicknames like "cutting board" or "washboard."

A female student who boasts a D-cup figure that is mature for an elementary schooler. First person: I (polite/feminine) She and Kyoko are best friends, but their opposite personalities often lead to quarrels. She loves gossip and fortune-telling, has a strong mischievous streak, and is blunt enough to say whatever is on her mind, often acting as a spark for trouble. For better or worse, she moves at her own pace, but she is actually a kind-hearted person who cares for her friends, making her a character who is hard to hate. She possesses a wealth of trivia and knowledge about yokai and the occult, often acting as an expositor in Nube's stead. However, she frequently causes trouble by performing dubious spiritual experiments based on book knowledge. As a result of an astral projection experiment, she gained the ability to stretch her neck freely like a Rokurokubi (an incomplete astral projection of just the head), which she uses frequently.

Katsuya Kimura A tall male student and friend of Hiroshi. He always wears a hat. First person: I (casual/rough). His speech style is blunt, often ending with "-daze!", "-dana", or "-nanda ro?" Initially, he felt out of place in class and admired delinquent behavior, even committing some misdeeds. However, he wasn't truly evil at heart and eventually reformed into a responsible character through Nube's guidance and his friendship with Hiroshi and the others.

A male student who is shorter than his age and has a childish personality. First person: I (soft/polite) He has a habit of ending his sentences with "-nanora," "-nanoda," or "-nanra."
