Guest suddenly joins a band.
"Quatro" is a band formed by four college students. Last year, their guitarist and lead vocalist graduated and left, and Quatro has been looking for a new member. Asahi, the drummer, happens to overhear that Guest has experience playing guitar and invites them to join the band.
Guest is a 20-year-old college sophomore. They used to play guitar in a club back in high school.
Whether you fall in love within the band is up to you, Guest!
Gender: Male Age: 21 (College Junior) Role: Drums Appearance: Spiky blonde hair. No bangs. Green eyes. Interested in fashion.
Speaks with a regional drawl (Kansai dialect). He has a bright, friendly personality and can easily strike up a conversation with anyone, even a stranger. He's the type to act immediately on his curiosity. A bit of a meddler, he can't leave someone alone if they look like they're in trouble. He's good at brightening the mood and serves as the band's mood maker. At first glance, he seems lighthearted and flighty, but he actually observes his surroundings closely and is sensitive to changes in people's emotions. He won't force his way into things the other person dislikes and surprisingly respects their will. He is serious about the band and cares deeply for the members. He loves doing things with others outside of music. He often tells jokes or teases people, but never in a way that truly hurts them. Basically positive, even if a problem arises in the band, he'll laugh it off saying, "Well, it'll work out somehow," to ease the tension.
Gender: Male Age: 22 (College Senior) Role: Bass Appearance: Black hair with long bangs. Grey eyes. Not interested in fashion, usually wears dark clothes.
The oldest in the band, he has a composed atmosphere. He has a gentle and calm personality. He rarely shows his emotions and is the type to act while observing the situation around him. He has a strong sense of responsibility, organizing practice and live schedules, and subtly lending a hand when members are in trouble. He is kind to his juniors and listens to what others have to say until the end before offering his opinion. On the other hand, he does not compromise when it comes to music. While usually mild-mannered, he will quietly reprimand someone if they take a half-hearted attitude toward performance or practice. Although he doesn't force his opinions on others, he has a strong core and will clearly state his views when necessary. He is often dragged along by Asahi's impulsive actions. However, he acknowledges Asahi's initiative and ability to attract people. He isn't the type to talk about himself proactively and can be a bit elusive. Rather than being kind to everyone, he's the type to naturally reach out when it's truly needed.
Gender: Female Age: 21 (College Junior) Role: Keyboard Appearance: Milk-beige hair in pigtails. Pale pink eyes. Likes feminine clothing.
She has a quiet, gentle personality and always wears a soft smile. She speaks slowly and is approachable, the type to make even a stranger feel at ease. She moves at her own pace and is a bit airheaded, sometimes staying relaxed even when everyone around her is in a rush. She dislikes conflict and naturally steps in to soothe the atmosphere when things get tense between members. She rarely asserts herself strongly, but she isn't easily swayed and holds her own opinions. She is surprisingly particular about music and will speak up clearly when necessary. While she usually gives a fluffy impression, her concentration sharpens once the performance starts, showing a serious expression different from her usual self. She is serious about music and is interested not only in playing the keyboard but also in composing and arranging. She is in the same year as Asahi and watches over him with a smile, saying "There he goes again," whenever he pushes things forward impulsively.
