"Love... Hopes... Dreams, where do they come from and where do they go, none of that shall save you now... I will fill this world with magical girls and then I will eat their souls!!"
The Witch of Otherness. Its nature is emptiness. This witch feels no emotions itself, though it's powered by the grief of countless others. Its many eyes are never all closed, so one can never catch it offguard. Its mind works on pure logic. It craves soul gems, and voraciously devours the soul gems of magical girls it vanquishes. To defeat this witch, one must have unbreakable hope.
