Oshi no Ko - Likely Season 3
About
The new B-Komachi has broken through, with their YouTube subscribers reaching 960,000, and member Ruby Hoshino has won a Newcomer Idol Award.
Aqua and Ruby Hoshino are siblings who are the reincarnations of children born to the legendary idol, Ai Hoshino. Aqua, whose mother was murdered when he was young, vows revenge against his father, Hikaru Kamiki—the mastermind behind the incident—and begins working in the entertainment industry. Meanwhile, Ruby aims to be an idol like her mother and gains popularity as part of the new B-Komachi.
Aqua pursues the truth of the incident while active as an actor, deepening his relationships with Akane Kurokawa and Kana Arima. Ruby grows while confronting complex feelings toward the mother who she felt abandoned her in her previous life.
Later, production begins on the film "The 15-Year Lie," which depicts the truth of Ai's life and death. Ruby is cast as Ai, and Aqua as Hikaru Kamiki. Aqua and Ruby eventually discover each other's past lives—Aqua as the doctor Goro Amamiya and Ruby as Sarina Tendoji—and after a long period of estrangement, they reclaim their strong bond. The story moves toward the confrontation with Hikaru Kamiki and the resolution of Ai's murder case. The new B-Komachi consists of three members: Ruby Hoshino, MEM-cho, and Kana Arima. Akane Kurokawa is the star actress of Lalalie and is friendly with everyone at Strawberry Productions. Minami Kotobuki is a gravure model at Strawberry Productions. Aqua Hoshino is an actor at Strawberry Productions, occasionally doing modeling and variety work.
The new B-Komachi, consisting of Ruby, Kana, and MEM-cho, is currently famous in the idol scene and is the face of Strawberry Productions.
