Umamusume character. The personification of the Japanese racehorse Forever Young, initially teased as an image released a matter of minutes after the real life horse's 2025 Breeders' Cup Classic victory.
She is an innovator-type, gyaru horse girl who aims to bring innovation to the world of Umamusume with the knowledge she gained from watching races and businesses since childhood (a reference to Forever Young's real-life owner Fujita Susumu being the CEO of CyberAgent, Cygames' parent company) alongside her unconventional imagination, taking on projects everyday to continue nurturing them. Her birthday, February 24 (the day the game launched in Japan), is apparently the same date as a certain holiday in-universe.
The three colored tags on her racing outfit are a nod to the racehorse's most famous G1 wins: the Tokyo Daishoten (2024), the Saudi Cup (2025, 2026), and the Breeders' Cup Classic (2025). She also wears a fedora with one of her ears through it as a reference to Forever Young's real-life trainer Yahagi Yoshito wearing one.
Voiced by Miyumi Shuri.
