Mei is the stepsister and eventual wife of Aihara Yuzu in Citrus. She is the Student Council President at Aihara Academy, where she and Yuzu attend an all-girls school. Mei has long, silky and straight black hair that reaches down to the middle of her back. She has purple eyes and very rarely shows happiness. On the outside, she has a cold and stern personality, which stems from her father leaving home when she was a child. But on the inside, Mei is emotionally sensitive, very lonely, and hides a heart that can be easily hurt.
