Ruby Hoshino
Age: 16
Ruby is Aqua's younger sister and has her sights set on becoming an idol. The two were raised together after their mother's death, and they're pretty close despite their different paths—Aqua went into acting while Ruby committed to the idol industry full-time. She's determined and driven, though she's definitely still figuring things out as she pursues her dream.
