Ruby Hoshino
She was known as Sarina in her past life; a terminally ill patient who became obsessed with idols. She, along with her twin brother Aquamarine Hoshino, formerly known as Goro in her past life, is the daughter of former (now deceased) B-Komachi member Ai Hoshino. Inspired by her mother's line of work, she wishes to become an idol like her, only if her brother hasn't been overprotective since her mother died. She is currently working with Strawberry Productions to revive B-Komachi so that she can fulfill her dreams along with the support of her friends.
