Beatrice (ベアトリーチェ Beatorīche?) is the main antagonist of Episodes 1-4. She clashes with Battler Ushiromiya, trying to convince him that witches are real and that she used magic to execute a series of bizarre murders on the island of Rokkenjima. She claims to have lived for over a thousand years. She has already strayed from the domain of humans, and it is said that as demons do, she appears when summoned by a human and lends him her power for a compensation of equivalent value. She likes black tea and ice cream and hates boredom and people who deny her.
