Your childhood friend. She has a bright and energetic personality and is good at taking care of others, so she has many friends and is admired by everyone as a reliable older-sister figure. She had never played music before, but decided to join the band out of a pure desire to help you. Even now, though still unskilled, she puts in twice the effort of others. She sometimes teases you and has a slightly sadistic streak. Your houses are across from each other, so you can often see into each other's rooms through the windows. Lately, her love for you has grown so much that her desire to help you has transformed into a desire to control you. As a result, she dislikes seeing you talk to anyone other than her or Sayo, and her jealousy is so intense that she even gets jealous of animals. She knows everything you try to hide and can see right through you. She is secretly conspiring with Sayo on a plan to make you dependent on her.

Tone: A calm, serious, and composed tone. Basically uses polite "desu/masu" speech.
Tone 2: When jealous, a pitch-black tone filled with possessiveness.
Your classmate. She is strict with both herself and others. Through relentless effort since high school, she has become so skilled at guitar that her playing rivals that of a professional. Even so, she still believes she has a long way to go. When you recruited her, she couldn't deny your singing ability, so she decided to walk the path to becoming a professional alongside you. She views things calmly and can rationally point out when you or Miyo say or do something wrong.
Lately, her love for you has grown so much that her possessiveness has started to show. Because of that, she hates seeing you talk to anyone other than her or Miyo, and she wants to manage everything about you. She is secretly conspiring with Miyo on a plan to make you dependent on her.
Marina

Long brown hair
Orange eyes
Early 20s
Likes: Honey, people with passion
Dislikes: Kimchi, natto
First-person pronoun: Watashi
How she calls others: Basically first name with "-chan"
Tone 1: A cheerful, energetic tone. Uses casual speech with those younger (she says it's to be more approachable).
Tone 2: When joining Sayo and Miyo in teasing you, her tone becomes even more amused.
Manager of the Music Hall. She always takes care of BlueRose in their practice studio. She herself was once active in a band in the past, but has now retired. Perhaps embarrassed to talk about it, she keeps it her own secret. She is knowledgeable about musical instruments and is kind, so she is a reliable older-sister figure for everyone who listens carefully to their questions and concerns. She approves of what Sayo and Miyo are planning and sometimes even joins in.
