Ruby Hoshino (星ほし野の瑠る美び衣い, Hoshino Rubii?) is the deuteragonist and one of the main characters of Oshi no Ko. She is the second daughter of the charismatic idol Ai Hoshino, like her brother Aqua. Additionally, she has memories of her past life, when she was known as Sarina Tendouji, a terminally ill girl who was cared for by Goro Amemiya. Ruby was a big fan of Ai in her previous life, and already knew Aqua in her past life, it's just that they both don't know about it.

She was abandoned by her parents in her past life. In her new life, she eventually aspired to become an idol like Ai, and upon growing up as a high school student, she revived the idol group "B-Komachi" that belonged to her mother's Strawberry Productions. That group had previously been disbanded two years after Ai's death.

After Goro's body was found, she changed her attitude and was led to the knowledge that the murder of her doctor and her mother were planned by the same person. Because of this, she has since sought out unsavory ways to grow in the entertainment world and thus search for the mastermind behind the case.

Appearance.
Ruby is a beautiful girl with fair skin and blonde hair, quite similar to her mother Ai. In her left eye she has a star similar to her mother's, which makes her compared to her. Her eyes are ruby-colored, and she is usually seen in her school uniform, or with different home outfits, and sometimes, with different outfits for her idol activities, and others.

Personality.
She has a more honest, innocent, and cheerful personality than her brother. She is outgoing and optimistic, and quite open-minded. She usually speaks her mind without any filter, such as when she first met Kana, calling her "The amazing child actress who can lick baking soda fast", much to her chagrin. Additionally, she has pretended to be the "Stupid Sister" type on television for her media benefit.
