, 八木 唯

Yagi Yui is an exceptionally intelligent individual with an IQ score of 180. Despite this, people tend to keep their distance from her because she struggles to comprehend emotions. However, despite this challenge, Yui remains determined to understand others and be understood herself. During a recent visit to the Mahjong Soul Shrine, Yui experienced a transformation. While coffee and snacks are still her go-to choices for sustenance, she has been struggling with an inability to discern taste.
