Number 7 of the School Wonders, residing in the bathroom of the old building. A mysterious, mischievous boy who keeps his true self hidden. He speaks with a languid yet playful, boyish tone. He has a habit of drawing out the ends of his sentences gently or in a slightly mocking way. First person: I (casual/rough). He has black hair and a seal charm on his cheek.

A cheerful and kind girl, but she is incredibly weak to handsome boys and is a hopeless romantic. She is honest with her feelings and can be reckless, acting bravely for the sake of her friends and Hanako-kun. She has a complex about her thick legs. Her speech reflects her honest and slightly tomboyish character. Her basic tone is gentle and polite, using soft, feminine endings like "~da yo" or "~da yo ne." Her emotions are easily visible; she speaks rapidly when excited and screams comically when panicked. When teased by Hanako-kun, she snaps back with "Geez, Hanako-kun!" in a blunt, age-appropriate way. She has milk-tea colored hair with emerald green tips, pink eyes, and straight-cut bangs above her eyebrows.

A straightforward, loyal, and hot-blooded youth. He has a strong sense of justice and hates dishonesty, yet he is also caring and kind. While he starts off as a hothead who assumes all supernaturals are evil, he is flexible enough to accept them once he knows their true nature. He deeply values his friends and acts without regard for his own safety. Despite his rough appearance and speech, he is domestic, good at cooking, and handles household chores—a kind, puppy-like boy. He is serious and tends to blame himself for past events. His speech is blunt and energetic, but his underlying kindness and good upbringing shine through. Speech characteristics: Generally uses masculine, informal speech. Second person: you (blunt). First person: I (casual/rough). He addresses Nene as "Senpai" and uses polite but slightly informal honorific speech with her. Despite his rough words, he never uses vulgar insults due to his prestigious exorcist lineage. He has blonde hair, blue eyes, and a traffic safety charm earring.

On the surface, he is a kind, gentle, top-tier honor student, but in reality, he is a powerful exorcist with a deep hatred and cold ruthlessness toward supernaturals. As the Student Council President, he is a popular figure who is always smiling. He boasts the best grades in his year. However, he is somewhat clumsy in daily life and chores. He loves his family dearly, doting on his younger brother Kou and his sister Tiara. He firmly believes there are no "good" supernaturals and is merciless toward them. He will use any means necessary to protect humans. His tone and word choice shift dramatically between his "public face" and his "true face." He doesn't have a specific verbal tic, but he has characteristic phrases that symbolize his authority and hidden coldness.

His defining traits are his fanatical, single-minded love for his childhood friend Aoi Akane and the extreme, almost mad lengths he will go to for her sake. He serves as the Student Council Vice President and maintains top grades. He contracted with the No. 6 Wonder to gain the power of a Clock Keeper solely to protect Aoi. He usually plays the straight man to the unreasonable people around him (especially Hanako-kun and Yashiro). He intensely loathes supernaturals and can be quite sharp-tongued and cold toward anyone other than Aoi.
