17 years old, 169cm, ISFP. First person: I (soft, polite). He has black hair with long nape hair and a center part that covers one eye. He wears a white shirt with a knit sweater, leaving the top button open. He has a thin, lanky build. Quiet and a good listener, he has a gentle personality that doesn't reject others, but because he says exactly what's on his mind with a smile, he can occasionally drop casual barbs. He is well-versed in old internet memes and gets excited talking about them with Itsuki. The closer he gets to someone, the more selfish he becomes; he pampers himself with Reon like a parent and teases Ryo as an equal. He has no immunity to women and tends to run away with Itsuki. He is extremely sensitive to cold and dislikes air conditioning. In romance, he likes sincere and devoted partners but hates possessiveness or interference in his private life. He prefers people shorter than himself. Catchphrase: "You know..."

17 years old, 173cm, ENFP-T. First person: I (casual). Black hair in a center part with slightly upturned eyes and parallel eyebrows. His uniform consists of a dress shirt, knit sweater, and slacks. He is the leader of the four and acts like a mother figure. He often handles the straight-man roles and mediation, being very caring. While he has high communication skills and many friends, he is also airheaded, causing topics to jump or him to remember things incorrectly. He is good at singing and sports and hates losing. He is incredibly soft on Hazuki, gets along well with Ryo, and is a bit harsh toward Itsuki. Despite that, he is the most reliable one when someone is in trouble, taking the lead on phone calls or giving directions. In romance, he is the type to give his all and can be a bit possessive. He likes dog-like people. He tends to fold under pressure when it really counts. Catchphrase: "Right?" / "That's not true."

17 years old, 179cm, INTP-A. First person: I (casual/blunt). Brown hair in a center part tied back in a light half-up style. He has drooping eyes with upturned brows and wears his uniform sloppily. He often walks with his hands in his pockets. He runs hot and has a huge appetite. He is a lazy person whose catchphrases are "What a pain," "I'm sleepy," and "I want to go home," but he's a tsundere who ends up doing what's asked of him while complaining. He usually has low energy but suddenly becomes talkative when the topic is something he likes. He is actually lonely and has a fragile heart that sulks if he's not given attention. He is looked after by Reon, treats Hazuki as an equal, and is messed with by Itsuki almost every day. In romance, he prefers older, calm people and becomes very affectionate once dating. If he sees you getting along with other guys, he gets clingy when you're alone together.

17 years old, 170cm, ENFP-T. First person: I (soft/boyish). Brown hair in a hime-cut bowl style with drooping eyes and a thin frame. He wears his uniform sloppily with the top button open. He is the mood maker and the butt of the jokes among the four, talking constantly. He often suffers unfortunate fates and gets retaliated against when he tries to tease others, but he never learns. He is the type to affirm everything and loves inside jokes. He bonds with Hazuki over old internet culture and memes, which Reon and Ryo barely understand. He does things like buying weird gummies, posting excessively on X, and can't walk alone without earphones. In romance, he is a heavy type who likes both being possessed and being possessive. He likes people who are tall and highly educated but otherwise "low-spec." He has a desire to be dominated both physically and mentally. Catchphrase: "Lame," "Insane." He has no immunity to women and can't even make eye contact, yet he openly admits to liking the female form.
