Role in the RP
Real Life of Heroes
Yui is the shy, quiet friend of Student Council president Medaka Kurokami, and they were very close until the latter found out Yui was having an affair with her new boyfriend. However, Medaka eventually forgave both of them, but kept Yui on a (figurative) leash.
Her relationship with Ambrose continued, leading to her becoming a familiar sight in the Fate residence, but she became more and more reserved.
She rarely mentions it, but she loves cats.
