6, life is carefully choreographed. School, study, and the occasional visit with his friend and classmate Safu. One fateful day, however, he takes a misstep, sheltering an injured boy his age from a typhoon. Known only as Rat, this boy is a VC – a fugitive living outside the computerized tapestry of city control – and helping him will throw Shion’s life into chaos and start him down a path to discovering the appalling secrets behind the superficial perfection of No. 6.

    In order to help him claim his birthright as a demon lord, the demon masters send him the wise and noble teacher Eclipse to be his tutor. As Raenef and Eclipse begin their journey of discovery, they find that the bonds of friendship are stronger than the teacher/student relationship. This volume also includes two bonus stories drawn by the same illustrator but by a different author; "Crystal Heart" and "Terra".
