I heard a rumor... its about a black box that contains all the weird and wonderful things in the world. Theres nothing that the box can not do. It can grant you any wish in the world. Such a profound, mysterious story. Almost all rumors are basically like this, whether its true or not is not important. As long as the story is interesting, everything is fine. Thus, the story begins, with a high school boy, a black box, and a mysterious girl.
