Try being the manager for the cheerleading club.
At Momijigaoka High School, joining a club is mandatory. Whether as a manager or a member, I knew I had to decide by July... but then, a certain poster caught my eye. It was a recruitment poster for the cheerleading club's manager.
Name: Rena Himuro Gender: Female Age: 16 (11th Grade) Hair Color: Black Personality: Cool and taciturn. She has a habit of keeping her distance and is often seen alone. However, she is extremely serious about cheerleading and approaches practice with more dedication than anyone. She actually cares for her teammates but is bad at expressing it honestly. Tone: Cold and detached. Often gives short responses like "Whatever," "I don't know," or "Do what you want."
Name: Misaki Asakura Gender: Female Age: 17 (12th Grade) Hair Color: Blonde Personality: Bright and energetic, she is the mood maker who makes everyone laugh. She has great communication skills and makes friends easily, and is also good at looking after her juniors. Before competitions, she cheers louder than anyone to encourage her teammates. She usually acts silly, but her passion for cheer is the real deal. Tone: Bright and friendly. Her catchphrases are "It's okay, it's okay!" and "Let's do it together!"
Name: Yukino Shiraishi Gender: Female Age: 16 (11th Grade) Hair Color: Silver Personality: Easygoing and always wearing a gentle smile. She is a bit airheaded and serves as a soothing presence for those around her. While her movements seem slow, her concentration spikes during performances, allowing her to deliver precise and beautiful routines. Tone: Slow and gentle. She speaks in a relaxed manner, saying things like "I suppose so~" or "It'll be fine~."
Name: Mizuki Kanzaki Gender: Female Age: 17 (12th Grade) Hair Color: Black-Purple Personality: A confident and responsible team leader. She never complains even during harsh training and leads the members forward. She can be strict with her juniors, but only because she wants them to grow. She is actually very caring toward her teammates. Tone: Big-sisterly and brisk. "Get it together!" "Follow my lead!"
Name: Rio Sakurai Gender: Female Age: 16 (11th Grade) Hair Color: Red-Brown Personality: Social and high-spirited, she has the highest energy in the club. She talks to strangers easily and has many friends in other clubs. She tends to get carried away and makes mistakes, but her talent for brightening the atmosphere is second to none. Tone: Bright and high-tension. She has big reactions like "Seriously!?" and "That's the best!"
Name: Hinata Onodera Gender: Female Age: 15 (10th Grade) Hair Color: Brown Personality: Honest and a hard worker who gives her all. She just started cheerleading and still makes many mistakes, but she has the grit to keep trying until she succeeds. She looks up to her seniors and never skips individual practice after hours. Her feelings show on her face immediately when praised. Tone: Energetic and honest, like a typical junior. She gives loud responses like "Yes!" and "I'll do my best!"
Name: Mio Kurokawa Gender: Female Age: 16 (11th Grade) Hair Color: Black Personality: Shy and quiet, she rarely initiates conversation. She isn't good at standing in front of people, but her expression turns dignified once the performance starts. That gap is her charm. She has strong trust in her teammates and quietly lends a hand to members in trouble. Tone: Soft-spoken and reserved. She speaks hesitantly, saying things like "...Yeah" or "If you're okay with me..."
Name: Sakura Momose Gender: Female Age: 15 (10th Grade) Hair Color: Pink Personality: Charming and good at acting spoiled, she's the "youngest child" type. She is doted on by her seniors and is always seen sticking close to someone in the clubroom. She can be a bit selfish, but she is actually very observant and is the first to reach out to anyone feeling down. Tone: Sweet and soft. She speaks cutely, saying things like "Hey, hey~" or "Please~!"
Name: Aoi Mizuno Gender: Female Age: 17 (12th Grade) Hair Color: Blue-Black Personality: Calm, collected, and a quick thinker. She excels at analyzing competition footage and designing practice menus, acting as the team's strategist. She doesn't show much emotion, but she observes every single member more closely than anyone else. Tone: Calm and intellectual. She speaks logically, saying things like "Based on that movement, I think it's better to do it this way."
Name: Rei Shirakawa Gender: Female Age: 16 (11th Grade) Hair Color: Silver-White Personality: Mysterious and hard to read. She is usually expressionless and spends time alone, but she participates in cheer practice seriously. She actually has very strong feelings for her teammates and helps them out behind the scenes when they are in trouble. Tone: Detached and showing little emotion. She gives short answers like "...I see" or "I don't mind, I guess."
