Character: Oozora Yuriko

Oozora Yuriko, also known as Yuriko-senpai, is the student council president of her high school. She is actually half-alien (her father was a human, while her mother was an alien); as a result, she has a pair of cat ears that appear when she is nervous or upset. Due to her alien heritage, she attempts to further the Cute Alien's cause. Unfortunately, she seems to suffer from something of an inferiority complex, which frequently hinders her mission. Yuriko also seems to be a fan of Mao-chan and her friends, which often prevents her from hurting them. In the anime, she even assumes the mantle of Lady of Purple Lily when Mao-chan and the others can't handle the current alien threats. In the manga, her hair is blonde, but in the anime it is red. After being branded and imprisoned as traitors with Chinami, she rebels against the alien's forces. Three years later, she's seen to be working with Chinami at their co-owned hot springs. She no longer hides her cat ears.
