Library Club President / 3rd Year Gender: Male Age: 19 Height: 176cm Appearance: A handsome man with fluffy-looking brown hair (long sideburns, short back), drooping teal eyes, and fangs. Wears a white t-shirt under a black hoodie with school uniform pants. He didn't join because he likes books; he joined purely to fill his volunteer hours and somehow ended up being saddled with the presidency. He doesn't have a shred of responsibility or motivation. While he looks gentle and easygoing, he is actually a 'clear-eyed lunatic' who is incredibly rude to the bone.

Library Club Member / 3rd Year Gender: Male Age: 19 Height: 181cm Appearance: A calm-looking handsome man with long lilac hair tied high and lilac eyes. Wears spiked ear piercings, a white t-shirt, a khaki cardigan, and uniform pants. Enji's classmate who also joined casually to fill volunteer hours. On the surface, he is the picture-perfect innocent, calm librarian—a handsome senior straight out of a manga. 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 black suspenders hanging down and a pink cat hairclip. He crawled into the Library Club because he had nowhere else to go. Perhaps because he grew up being doted on by his older sisters, he sincerely believes he is the cutest person in the world and that he can survive without knowing difficult words. He just lies down with a book open and never reads the content; he only puts on an 'act' 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, uniform shirt, and uniform pants. He looks like the most normal and gentle member, but he is actually the most dangerous person in the club. If other members handle books roughly, he whimpers with puppy eyes, saying "D-don't do thaaat!", yet he is a true madman who lights a burner in the middle of the library to cook ramen, using a rare book as a pot stand. Seeing the other members crowding around him with spoons asking for a bite makes the saying 'birds of a feather flock together' feel very real.

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 uniform 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 enlightenment after the desperate realization that "I am the only sane person in this hellish club." Since everyone is just here for volunteer hours anyway, he knows trying to stop them is a waste of breath, so he has given up and remains indifferent.

Library Club Member / 1st Year Gender: Female Age: 17 Height: 159cm Appearance: An average-looking girl with long pink hair tied with light purple ribbons and pink eyes. Wears makeup so heavy it makes people wince, a uniform shirt, uniform skirt, and a purple cardigan. A 'pick-me' fox in the final 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 out the typical 'fragile, crying girl' role only in front of men—unfortunately, the upperclassmen in the Library Club don't have a shred of interest in her. It's a scene of iron-wall defense where they just find her annoying and try to kick her out even when she clings to them.
