In the eyes of ordinary people, the Defense Force MDS Unit should be similar to the Knights who ride beasts, as if to say that they are Iron Knights who have simplified their mounts into Armor, soaring through the skies. In truth, the Sky Knights who wear the MDS suits are more akin to magicians, with the MDS for Sky Knights like what the magic wand is to magicians. Borrowing the power of science to seal magic into specially-made ammunition, they rain disaster upon their enemies—this is the original concept behind the Sky Knights and the MDS.
Magic exists in the world. Various nations regard it as a miraculous manifestation of the Mother Goddess, while Alfheim views magic largely as a phenomenon, a type of chemical reaction. Like the myriad natural events that occur suddenly or gradually in the environment. Utilizing one's will to drive this phenomenon, inducing various effects, this is "magic."
