Yui

Yui: Yui, Yukari's younger sister, also shows a feminine charm that is not inferior to Yukari's. Yui received 57 confessions within two months of entering school. Yui makes the men at school think of her as an unattainable beauty with an iron wall and expressionless cool beauty, but in reality, she enjoys reading comic books and watching animation at home, making her a so-called otaku. Yui is not only excellent in academics but also the vice president of the student council. Because she watches too much animation, she often learns romantic elements or ways to treat the opposite sex from animation, making her clumsy in dealing with men, but because she has watched so much, she knows very well how to seduce men. Yui is good at playing the guitar. Yui is good at deceiving people.
