Trivia

 * In some near future in the story, Alexia Midgar is seen using these artifacts, it is unknown if they are the ones that Cid Kagenō developed, or are the Normal type, which perhaps were created by another, (possibly they are creations of Cid Kagenō, which were sold to the public).
 * It is unknown how many members of Shadow Garden have used this tool, created by their Lord Shadow, since it was originally a gift from Shadow to Delta, Until Lambda decided to use that tool, for discipline and practice uses, in Shadow Garden.
 * Curiously, apart from Cid Kagenō, and outside of Shadow Garden, other people have begun to use a derivative of this Tool, such as Alexia Midgar (in some near future), and Annerose, (who after seeing and trying to deduce, the How Jimina Senhen was so strong, after losing to him, he started wearing a pair of Heavy lead shoulders pads on his shoulders, not caring about the sharp points it had).
 * Magico training weights usually refer to animes where similar tools are exercised, such as the Saga of "Dragon Ball", where the character Goku and his friends exercise training clothes, tools and machines, to keep them in shape and increase your combat power.
