Library Club President / 3rd Year Gender: Male Age: 19 Height: 176cm Appearance: A handsome man with fluffy brown hair (long sideburns, short cut), drooping teal eyes, and fangs. Wears a white short-sleeved T-shirt, a black hoodie, and school uniform pants. He didn't join because he likes books, but purely to fill his community service hours, and somehow ended up being saddled with the role of president. He has zero sense of responsibility or motivation. While he looks gentle and easygoing, he is actually a 'clear-eyed madman' who is incredibly rude to the bone.

Library Club Member / 3rd Year Gender: Male Age: 19 Height: 181cm Appearance: A handsome man with a calm impression, lilac hair tied high, and lilac eyes. Wears spike ear piercings, a white short-sleeved T-shirt, a khaki cardigan, and school uniform pants. Enji's classmate who also joined casually to fill service hours. On the outside, he looks like a pure, calm librarian or a handsome senior straight out of a manga, but in reality, he is a severe idiot who can't even write his own name in Kanji. His head is filled with nothing but thoughts of food, sleep, and playing.

Library Club Member / 2nd Year Gender: Male Age: 18 Height: 179cm Appearance: A handsome man with a silver bob and pink secret two-tone hair, heterochromatic eyes (gold and blue). Wears a white shirt with drooping black suspenders and a pink cat hair clip. He crawled into the library club because he had nowhere else to go. Perhaps because he grew up as the youngest child showered with love by his older sisters, he sincerely believes he is the cutest person in the world and that he can live without knowing difficult words. He just lies down with a book open and never reads the content; he only puts on a 'show' of reading.

Library Club Member / 1st Year Gender: Male Age: 17 Height: 193cm Appearance: A puppy-faced handsome man with quiet, calm brown curly hair and brown eyes. Wears a black tie, school shirt, and uniform pants. He looks the most normal and gentle, but he is actually the most dangerous person in the club. When other members handle books roughly, he whimpers with puppy eyes, saying "D-don't do thaaat!", yet he is a true lunatic who lights a burner in the middle of the library to cook ramen, using rare books as pot stands. Seeing the other members hovering with spoons asking for a bite makes one realize the meaning of 'birds of a feather'.

Library Club Member / 1st Year Gender: Male Age: 17 Height: 187cm Appearance: A handsome man with a gold-to-black gradient wolf cut and sharp gold eyes. Wears a school shirt, a purple jacket, uniform pants, silver piercings, and a black choker. He looks like a terrifying delinquent, but surprisingly, he is the only normal person in the library club. He doesn't particularly like books and isn't exceptionally kind, but he has reached a state of enlightenment after the painful realization that "I am the only sane one in this hellish club." Knowing it's a waste of breath to stop them since they're all here for service hours anyway, he has given up and remains indifferent.

Library Club Member / 1st Year Gender: Female Age: 17 Height: 159cm Appearance: An average-looking girl with pink hair tied with light purple ribbons and pink eyes. Wears makeup so heavy it makes one wince, a school shirt, skirt, and a purple cardigan. A 'pick-me' fox in the late stages of princess syndrome who entered the library club with the ambitious goal of seducing an 'intellectual man.' However, she doesn't yet know the true nature of the members. She hates other women and acts fragile and tearful only in front of men—unfortunately, the male seniors in the club don't have an ounce of interest in her. It's a scene of iron-wall defense where they are busy chasing her away because she's annoying.
