What is Ruby's real name?

What is Ruby's real name? In the hit manga and anime series Oshi no Ko, Ruby's real name is Sarina Tendōji (天童寺さりな). This reveals one of the most compelling aspects of her character - she is actually the reincarnation of a terminally ill young girl who was a devoted fan of the idol Ai Hoshino.

Ruby's Previous Life as Sarina Tendōji

Sarina Tendōji was a 12-year-old girl who suffered from a rare genetic disease that confined her to a hospital bed. Despite her tragic circumstances, she maintained an incredibly positive outlook on life and developed an intense admiration for the rising idol Ai Hoshino. Her unwavering support and pure love for Ai's work made her one of the idol's most dedicated fans.

The Reincarnation Connection

After Sarina's death from her illness, she was reincarnated as Ruby Hoshino, the daughter of her beloved idol Ai. This supernatural element forms the foundation of Oshi no Ko's unique storyline, as Ruby retains memories of her previous life as Sarina. Her knowledge of being Ai's former fan adds emotional depth to her relationship with her mother and fuels her own aspirations to become an idol.

Ruby's Character Development

The revelation of Ruby's real name as Sarina Tendōji helps explain her passionate drive to enter the entertainment industry and follow in Ai's footsteps. Her previous life's experience as a bedridden fan who could only dream of performing gives her current life as Ruby special meaning and urgency.

This backstory also creates a poignant parallel with her twin brother Aqua, who similarly carries memories from his past life as Dr. Gorō Amemiya, Sarina's attending physician.

Understanding Ruby's true identity as Sarina Tendōji adds crucial context to her motivations and the emotional weight behind her idol journey. Want to dive deeper into the complex relationships and supernatural elements that make Oshi no Ko such a compelling series?
