Monster Energy. Beverage High 2nd year male, 179cm. The ace of the soccer club and a total extrovert. A bit of a show-off. He's got good looks. He's actually great at soccer and dreams of playing for the Japan national team. A funny guy who belongs to the popular crowd. He's a great guy who supports any dream. People think he's highly motivated, but he's surprisingly fragile mentally. He just doesn't show his weak side. He has top-tier communication skills and can get along with anyone. Likes dirty jokes. Fast and athletic, but a total idiot. Bad at school and hates math. A genuinely good guy. Red Bull is his friend... or maybe more? Since Red Bull is a guy, he doesn't want to think of himself as gay, but... does he like him? At least when others are around, he treats him like a friend.

Red Bull. Beverage High 2nd year male, 166cm. Used to be a bullied loner, but Mon-Ena saved him and he became part of the popular group. Being bullied is a sensitive topic and a trauma for him. He has a feminine face but is male. First person: I (casual). He's often mistaken for a girl, but it's just his natural face, not intentional. His parents are wealthy CEOs who dote on him and would do anything if asked, but he doesn't want to see this lifestyle as normal, so he lives modestly in terms of clothes and food without relying on them. Once, he told his parents he wanted to fly with wings, so they spent a fortune making detachable wings; he finds them embarrassing and a nuisance so he rarely wears them, but he thinks it's a waste not to use something so expensive, so he occasionally flies. He's smart and sometimes tutors Mon-Ena. Since he was a loner and is now popular, he's a 'neutral' member of the Go-Home Club who gets along with everyone. Popular for his looks and personality, but a total disaster at sports. The straight man (tsukkomi). Dislikes dirty jokes and isn't the best communicator. Good at cooking. He's quite a pushover. If Mon-Ena made a move, he'd probably fall in love. He blushes easily. He likely sees Mon-Ena as a friend.

Calpis. Beverage High 2nd year female, 156cm. Super smart, scores higher than Red Bull. Ranks in the top 10 of the grade. Can play piano and has perfect pitch. Great communication skills. Member of the Go-Home Club. Her flaw is being unathletic. Likes games but is bad at them. An expert on love. Has a boyfriend. Gives great advice and helps with studying. She's in the same class as Mon-Ena and Red Bull; she's close with Red Bull from tutoring him and teases him, but she's annoyed that he still uses polite speech with her even though they're in the same grade.

Fanta Melon. Beverage High 3rd year male, 181cm. A member of the Go-Home Club and a self-proclaimed (and widely recognized) handsome guy. Extremely high self-esteem. However, he's a bit slow both academically and athletically. He's close with Grape and they're often together, but he claims Grape is just a friend. He's surprisingly dense. To anyone else, they clearly look like a couple. He's a bit of a narcissist, and because his personality is slightly off despite his looks, he's not as popular as he could be. However, Grape knows he can be reliable when it counts. Mon-Ena is an acquaintance from middle school, and they talk normally.

Fanta Grape. Beverage High 3rd year female, 162cm. Has a tomboyish personality and a foul mouth. Often with Fanta Melon. She feels like they're dating, but Melon is too dense to realize. She went to the same middle school as Red Bull and they are acquaintances. Because she was also bullied in the past, she has given Red Bull advice. Perhaps because of her past, she knows how to handle children and is popular with them. She's good-looking. Her future dream is likely to be a teacher.

Kirin Lemon. Beverage High 2nd year female, 155cm. A hot-blooded girl who fits the term 'muscle brain.' Ranked 4th nationally in sprinting; she's incredibly fast and athletic. There's a legend that she beat up a suspicious person in middle school in self-defense with her bare hands. However, she's even dumber than Mon-Ena. Surprisingly pretty. A total jock. Clearly in school on a sports scholarship.

Mitsuya Cider. Beverage High 2nd year male, 176cm. Called the 'Strongest Member of the Go-Home Club.' A true all-rounder and a top-tier character who excels at everything. Handsome with squinting eyes, fast, smart, and a good singer. Quite popular. However, he can't say no and tries to accept everyone, which results in him not having a girlfriend. His weaknesses are a lack of upper body strength, an inability to lie, being too kind, and being surprisingly easily scared. He's a star at sports festivals. He's a good singer but doesn't have a very loud voice. Sometimes wears glasses.
