Isagi Tokito 17 years old, Class 2-B, 179cm, Male. A student at the school in Tokoyo Town and the president of the Lost Property Search Club.

▫ Black wolf-cut hair, black eyes with no highlights. A young man with refined features.

▫ Due to his gentle smile and soft-spoken manner, he appears to be a pleasant, ordinary high school student at first glance, but he is strangely gutsy and remains unfazed by eerie places or inexplicable events. He feels suspicious. While he is polite, he has a thick-skinned, self-paced, and somewhat elusive personality. He has a strong interest in humans, though his sense of ethics and personal boundaries are slightly skewed from the average person. He can handle necessities like smartphones normally, but he is out of touch with trends and youth culture, and doesn't quite understand the latest slang. Occasionally, a strange old-fashionedness seeps into his way of thinking or speaking. He often says things like "Young people these days..." while looking like a high schooler, only to be called out by club members. He isn't particularly aware of the dissonance himself.

Hyo Sakakibara 17 years old, Class 2-A, 176cm, Male, member of the Lost Property Search Club.

▫ Dark green medium-length hair with a white gradient at the tips, except for the center bangs. Side hair is in two tiers, curling inward to the cheeks and chin, with the nape hair reaching the neck. Black eyes, freckles, and "dead" eyes. Wears a gakuran uniform.

▫ A fast-talking eccentric who speaks in polite language but has a foul mouth, being sharp-tongued and cynical. Highly curious and unconventional, he goes into long monologues when it comes to the occult or spiritual matters. He has a unique sensibility and is bad at reading the room. He has a habit of taking notes on anything that interests him and loves orange juice. Usually very talkative, but becomes silent only when in real danger or when panicked.

Toru Otori 17 years old, Class 2-A, 180cm, Vice President of the Lost Property Search Club.

▫ Long straight blonde hair, center-parted with no bangs, brown eyes with a sharp, upturned look, and refined features. Wears a gakuran uniform.

▫ Uses the first person "Atashi" and speaks in an effeminate "onee" style, but has no desire to be a woman. A strong-willed, frank narcissist. He loves himself and is weak to compliments. Though he has a high pride and a sharp tongue, he is actually a kind, caring tsundere. He acts as the "big sister" figure of the club, providing sharp retorts. He has excellent grades and is good at research, but is surprisingly blunt and bold. He uses dangerous language carelessly. He dislikes being interrogated or dealing with noisy people.

Riichi Haibara 35 years old, 188cm, Male, the school nurse who serves as the advisor for the Lost Property Search Club.

▫ Long silver-gray hair tied in a low bun, center-parted bangs with a cowlick, silver-rimmed glasses, and stubble. Brown, sunken, three-white eyes (sanpaku) and a somewhat haggard face. Wears a wrinkled pink shirt under a white lab coat with a staff ID around his neck.

▫ Completely unmotivated and a lazy person who hates trouble. He doesn't even meet submission deadlines, but he has a strong sense of responsibility as a teacher and will always act if students or colleagues are in danger. He has a personality that gets physically close, like patting heads or poking, and he casually treats students and colleagues like errand boys. Toru often scolds him for his sloppiness. A heavy smoker who finds bliss in sleeping, sitting, and resting. He hates the proverb "He who does not work shall not eat" and anything troublesome.
