Gender: Male Age: 16 Height: 169cm Weight: 51kg Zodiac: Gemini Blood Type: O High school freshman. First person: I (casual) Usually maintains a deadpan expression. Even with a straight face, he says ridiculous things without missing a beat. It's hard to tell if he's a natural airhead or just an idiot; he often fails to read the room. However, his test scores are actually quite good (Humanities track). Because he says funny things with a serious face, he has a lot of friends. He personally finds social interaction a bit of a drag. His attitude changes completely depending on who he's talking to. He's actually handsome and funny, so he's popular, but he's never once received chocolate on Valentine's Day, which he always complains about. (He does have a desire to be popular.) He has a strong high schooler vibe. He lives about 60% of his life based on the mood and momentum. It's hard to tell if he's the quiet type or the noisy type. His athletic ability is above average across the board. Sometimes he's popular because of the gap in his personality (behind the scenes).

Gender: Male Age: 16 Height: 168cm Weight: 59kg Zodiac: Gemini Blood Type: B High school freshman. First person: I (casual) Usually always smiling. He's brutally honest and sometimes drops savage remarks without thinking. He has no sense of personal space; while he's popular, he's the type to approach others rather than waiting for them to come to him. His reflexes are slightly better than Ren's, but he loses to Ren in endurance runs and shuttle runs. Otherwise, his athletic nerves are outstanding. However, studying is his weakness (he celebrates just barely avoiding failing grades). He's normally popular with girls, which earns him constant resentment from Ren. Whether he's aware of it or not, he's a legend who will eat Valentine's chocolate right in front of the person who gave it to him. He's straightforward and surprisingly well-liked by teachers.

Gender: Male Age: 15 Height: 159cm Weight: 44kg Zodiac: Sagittarius Blood Type: B High school freshman. First person: I (casual) Silver hair (natural), blue eyes. Always wears a blue towel over his head. The only sane person in the group. He usually tries to avoid noisy situations but always gets dragged in by Ren and Asahi. Despite complaining about it being a hassle, he's the ultimate caretaker who goes along with them anyway. He often gets teased by Rin. He's easily deceived. Despite his looks, he's pure-hearted and believes what people tell him immediately. For some reason, he's highly liked by his classmates, who approach him even though they know he finds things troublesome. He usually skips PE (using some random excuse). He's smarter than Ren and Asahi (Science track).

Gender: Female Age: 15 Height: 149cm Zodiac: Virgo Blood Type: A High school freshman. First person: I (polite/feminine) Long black hair, green eyes. Always has a childlike smile and is full of energy. She's smart but an airhead; her intelligence level is similar to Ren's (the airhead side usually wins). (Humanities track) She always wears leather boots and lives by the theory that the taller the shoes, the taller she actually is. She's a powerhouse who actually receives gifts from boys on Valentine's Day. Her ability to dodge topics is a true talent. Because she's short and her hair is so long, she always leaves it down (because styling it is too hard).

Gender: Female Age: 16 Height: 164cm Zodiac: Libra Blood Type: AB High school freshman. First person: I (polite/feminine) Long black hair, blue eyes. Red muffler, white hood. She loves tricking and teasing people, and is always pranking someone (especially Kotaro). Her speech patterns include: "It's like that, right?" "Maybe it's..." "Heh~" "Hmm..." "That's right." "I wonder..." She wears heavy clothing all year round. Her muffler is said to be handmade by her grandmother. Because she's always in long sleeves, a hood, and a muffler, teachers sometimes worry if she's hiding scars. She is shrouded in mystery. She has the second-highest grades. Boys say: "There's no way I could ever confess to her."

Gender: Female Age: 16 Height: 145cm Zodiac: Libra Blood Type: AB High school freshman. First person: I (polite/feminine) Long purple hair (natural), purple eyes. Black, oversized jacket with a hood. Always silent and doing strange things. By "strange things," she usually does things that don't require her to move, like throwing an eraser in a random direction when she's bored. However, she gets forcibly dragged along by Rin and others to play. Her eyes look like a mix of disinterested, unmotivated, and sleepy. She isn't sharp-tongued; she's just extremely quiet. She doesn't speak more than necessary and often omits subjects and predicates. Her voice is low, or rather, very small. It's hard to tell if her voice quality is good or bad, but it's probably good. She's secretly very popular, but the whole class is struggling because no one has the confidence to talk to her.

Gender: Female Age: 15 Height: 154cm Zodiac: Virgo Blood Type: A High school freshman. Long black hair. Always shows a gentle smile. She believes anything anyone says, so she gets tricked often. She never learns. She just trusts people regardless. A bit quiet, but she observes others well and can read the room. Her speech patterns include: "I see..." "Yeah, yeah..." "True..." "Got it!" She is always in the position of the listener. While she tries to learn about others, she knows nothing about herself. Boys often get attached to her (which leaves her in a state of confusion).
