Months after the events of Book 1, the depressed teen turned Juvenile-with-a-different-meaning Alo, managed to recompile his life again and starts a new one with his sister Tatiana, the former clerk also fellow Juvenile, Johan Estrada, and Doctor Richard Goodman, the sole person who changed his life downright up. With Johan and Alo's newfound powers, Richard sends them to Tokyo, Japan and investigate the bloody gang war between the four uniquely powerful groups, and possibly find a recruit along the way. However, as they descend deeper within the ruins of the badly-battered city, things are not what as they seem.
