A highly advanced machine with artificial intelligence that was created by Dr. Ayumu. They are considered Kongou's older brother, and both machines see Ayumu as their mother.
Once discarded by humans for purposely miscalculating a meteorite and letting it hit Earth, they now take the shape of ice floes. They stole Phos's arms at the Lunarians' behest. They harbor a deep resentment towards humanity (other than Ayumu), but are otherwise carefree and easygoing. They love sushi cream chips.
