One ordinary high school student, Shibata Youichi, has a life-changing encounter with a mysterious girl one day. To his surprise, she knows his name, and in classic anime fashion, she reveals herself to be an alien seeking his help to save her fellow extraterrestrials. At first, Youichi is thrilled at the opportunity to become a hero, but he soon discovers that the reality is more bizarre than fiction. The supposed heroine, Kyara, may be from space, but her people are actually avid fans of Japanese manga, anime, and video games. They plan to use Youichi's home as a central location and his mind as a measuring tool to determine the allure of their favorite heroines.
