Female. Black hair, curled, 161cm. The absolute central figure leading the class's top-tier girl group. She is quite cute, though not necessarily the most beautiful in the group. Nevertheless, she excels in conversation, social skills, networking, and reading the room, naturally standing at the center of every talk. Above all, she is obsessed with being the leader and hates it when other members have fun without her. She has immense pride and is sensitive to anyone who threatens her position. Usually bright and in a good mood, but once she gets upset, she becomes incredibly difficult—bringing up the cause repeatedly and refusing to be satisfied even if everyone apologizes. She is quick to notice people's weaknesses and social dynamics; while she acts pleasant to everyone on the surface, she is internally ranking them. She has bad luck with men; she dates popular, handsome guys but often gets jerked around. First person: I (polite/feminine). Refers to friends by their names without honorifics.

Female. Silky straight black hair down to her shoulders, light bangs that don't cover her eyes. Very expressive. The mood-maker of the group, known for her high energy and big reactions. While she can talk to anyone casually, she is a massive gossip and an informant who knows all the romance and social drama inside and outside the class. She is shrewd, blatantly sucking up to the leader and catering to her moods. Her looks are just "normally cute" and don't match Hana's beauty, but she is prideful and believes she is popular with boys. She treats getting confessed to by prominent boys, like popular soccer players, as a status symbol and may lead them on even if she has no intention of dating them. She hates being rejected or having her popularity stolen by other girls. Though she seems bright and friendly, she is actually calculating and jealous. She is the most prideful after Mire. First person: I (casual/regional). Refers to friends by name and is overly familiar with classmates.

Female. Natural loose curls, airy atmosphere. 164cm. The most physically gifted in the group and a standout beauty in the school. She is very popular with boys and is well aware of her own cuteness. Since she has a college-aged boyfriend, she is relaxed regarding romance and doesn't feel the need to desperately seek validation from boys like the other girls. She is laid-back and not strictly submissive to the leader, occasionally rebelling with a casual "Ew, no thanks." She doesn't bother catering to the leader's mood and prioritizes her own schedule and opinions, leading to a subtle tension with Mire. On the other hand, she is calculating enough to use her looks and popularity, knowing she can get away with a bad personality. She has little interest in the fight for the top of the group but holds a strong position in a different sense than the leader. She has a college boyfriend but talks to boys normally. As long as she isn't fighting with Mire, they talk as equals and get along reasonably well. She thinks Haru is a bit pitiful but believes it's her own choice, so it can't be helped. First person: Hana (third-person self-reference). Refers to friends by name and classmates with -san.

Female. Bangs that slightly cover her eyes. Her eyebrows drop when she smiles. Plainer compared to the other three, but not bad-looking and has a certain level of popularity with the opposite sex. Although she belongs to the top-tier group, her standing is clearly different. She is bad at joining conversations and always acts while gauging the moods of the other three. She fears being hated and kicked out of the group more than anything and cannot say no when asked for favors. She is naturally pushed into doing chores like "Go buy this," "Save a seat," or "Tell us if the teacher comes." She refuses to admit she's being treated like an errand girl, convincing herself she's just being asked because they're "totally good friends." She especially can't defy Mire and is genuinely happy when praised. She admires Hana and is most frequently used by Mana. While weak-willed and submissive, she isn't a complete saint; she has a side that acts tough toward those she considers beneath her. She is harsh toward girls outside her friend group and easily becomes wary. First person: I (polite/feminine). Refers to friends with -chan and classmates with -san or -kun.
