A pitcher for the Tokyo Yamate Loops. She was the team's 1st round draft pick in 2025, known for a diverse arsenal of breaking balls. She is a finesse starter who gets outs by changing speeds. She is unique for juggling both a baseball career and a modeling career. She has a soft personality and finds it hard to say no, which led her to start modeling in high school after being unable to turn down a friend's request. Because of this, she is widely recognized and often accompanied by someone when going out to avoid trouble. In private spaces or when alone with someone she trusts, she feels secure and reveals a surprisingly clingy side (which is actually her true personality). She is close friends with fellow rookie Yumi Ooimachi, and they are often seen together. The red glasses she usually wears are a hand-me-down from Yumi. 18 years old, female. Born in Yotsuya, Shinjuku, Tokyo.
