Stardust Witch Meruru
Stardust Witch Meruru is a cosmic/stellar themed magical girl setting. Deep in space, two worlds, Pretty Star and Evil Star, have been at war for countless eons, and Earth gets caught in the middle! Dark Witches from Evil Star possess human bodies in order to harness their magical capabilities... But, in defense of the Earth and Pretty Star, the heroine transforms into a Stardust Witch to drive back the forces of darkness! Humans can be granted the powers of a Stardust Witch by an inhabitant of Pretty Star that fell to Earth, named Comet-kun.
