Bizarre creatures referred to as "Unknown" appear over the coast of Tokyo Bay. Defending against them is the mission of high school students in Tokyo, Kanagawa, and Chiba who possess a supernatural power known as "World." Among them all, the head of the Tokyo school, Ichiya Suzaku, defeats Unknown with particularly overwhelming power, but Tokyo's subhead, Canaria Utara, observes his lack of teamwork with a troubled expression.
