Mites are a kind of demon used by Summoners seen throughout the series.
Mites are one of, if not the weakest demons available to Summoners. They have a fulfillment level of 1 and are among the most common demons in the Ether. They are common a food source to other, larger demons. They are normally given out to first-year Battlemages, generally commoners, before they can acquire more powerful demons.
Mites resemble a large insect and come in a variety of colors from blue, red to white. They come in a number of different subspecies with the Scarab Mite being the most powerful. These Mites have the ability to fly and when the reach adulthood, grow a pair of mandibles capable of temporarily paralyzing a human. These demons may be small, but they can be very effective in battle.
Because of their small size and flight capabilities, Mites are often used as scouts before more powerful demons are sent in.
