"You can do anything if you put your mind to it." That is how Mio was raised… if you could call it that… by her rather lazy guardian Reki. Born on an island she has never been off of, Mio grows bored of her everyday life… That is until Sarah comes along. Sarah is a member of an organization that explores and manages many "Homes", islands much like Mio's. For Mio this is her ticket to adventure, excitement and the most interesting thing of all… school! But is the school ready for Mio?

Their city is filled with criminals and three incredible high schoolers. Yugo, Rikiya and Tasuku are determined to clean up the city with whatever means necessary, even if that means using violence. During a typical night of wiping out gangs, Tasuku comes across a beautiful girl held prisoner. She helps him survive what would have been a mortal wound by allowing him to see the future. Tasuku takes her home where he finds that her name is Noa, she doesn’t speak at all, and has no memory. Even more fascinating to Tasuku, she bears the same tattoo as the person he has spent years searching for.
