Noi Kasahara

Most likely the most beautiful girl at school, Noi becomes friends with Sunako in order to become closer to Takenaga, though genuinely values her friendship with Sunako and greatly admires her abilities. She is Sunako's first female friend and stands up for her when their classmates make fun of her. Because of her quick temper and romantic notions, she and Kyouhei often argue, particularly in regards to Sunako. Noi loves Takenaga unfailingly, but often questions the nature of their relationship as Takenaga is too shy to make his feelings toward her more explicit. Like the boys, Noi is not that good when it comes to housework.
