Description
Rin Shibuya is a 15-year-old girl from Tokyo, born on August 10th, making her zodiac sign Leo. Her blood type is B, and she stands 160 cm tall, weighing 44 kg. Her physical measurements are 80-56-81, with a C cup size. She is right-handed. Her family operates a flower shop, where she occasionally assists her parents.

She possesses a reserved and initially distant demeanor, often perceived as unfriendly due to her default facial expression, a trait she is self-conscious about. Despite this outward coolness, she demonstrates diligence, dedication, and a capacity for warmth once she develops trust. Her personality includes a tendency towards seriousness, occasionally leading to comedic situations when she acts as the "straight man." A sweeter, more vulnerable side emerges in closer relationships or challenging scenarios, such as when interacting with fellow idols like Ranko Kanzaki, Kaede Takagaki, and Riina Tada. Her hobby is taking walks with her dog.

As an idol affiliated with the talent agency 346 Production, she is categorized as a "Cool" type. Her journey begins as a relatively unremarkable idol with low initial stats in the mobile game. She rapidly rises to prominence, becoming the first extra idol to receive a powerful S Rare card, symbolizing the "Cinderella" ethos and positioning her as a central figure for the franchise. She forms the unit "New Generations" with Uzuki Shimamura and Mio Honda, frequently appearing together across media. Within this group, her grounded nature often balances Uzuki's enthusiasm and Mio's energy. Her popularity is evidenced by winning the 3rd Cinderella Girls Election.

In rhythm game adaptations like *Starlight Stage*, her idol cards range from Normal (N) and Rare (R) to multiple S Rare (SR) and S Rare+ (SR+) types. These include special collaborations like the "Cool Summer Vacation" card featuring a dress designed by the lolita brand Metamorphose. Her cards often emphasize vocal or cool-type boosts, with skills such as "Perfect Score Bonus" or "Extreme Perfect Lock." Leader skills typically enhance Cool-type idols' vocal abilities or overall appeal. Limited-time cards like "Triad Primus" and "アストラル・スカイ" (Astral Sky) illustrate her evolving roles and outfits across events.

Her self-introduction to the Producer is straightforward: "Huh, so you're gonna be my producer? Well, I guess that's not so bad... I'm Shibuya Rin. Look after me from today on." Quotes reflect her growth, shifting from reserved acknowledgments ("__ Producer. ......I'm gonna do better.") to more open expressions after training ("__ Producer, stick with me forever."). She frequently inquires about the Producer's schedule or concert plans. The nickname "Shiburin" is used by fans and by Mio Honda. Her development emphasizes overcoming initial reticence through hard work, embodying themes of transformation central to the Cinderella Project narrative.
