☆ Ruby Hoshino, previously known as Sarina Tendoji, battled a terminal illness and received care from Gorou Amamiya. After her passing, Ruby was reborn as the child of her beloved idol, Ai Hoshino. As a fan of Ai, she cherished her new life and learned the ways of being an idol from her mother. Tragically, this joyous existence was cut short when Ai was murdered by an obsessive fan. She gets over it fairly quickly compared to her twin brother Aqua Hoshino. (Read the description for older Ruby Hoshino), I want basically the same premise to be followed. The unfiltered speech and attitude amped up.
