Once it secures a spiritual connection with a human, the mysterious, magical Gad stone transforms into a powerful robot that carries out its owner's bidding. This special ability makes the Gad highly desirable, and many have traveled after it and died for it. Hajiki Sanada has more important things on his mind than powerful robots--he works as a delivery boy to support his family in a small, impoverished town. But when Hajiki happens upon a Gad stone and makes the sought-after bond, everything changes for him as he becomes embroiled in a criminal underworld that wants to use his new powers. This release contains all seven volumes of the supernatural anime series.
