The Golden and Endless Witch. An unpredictable enigma who is said to be a thousand years old, the one who is behind the Rokkenjima Massacre. In spite of her outward elegance, Beatrice is prone to being as undignified as one can possibly be, erupting into maniacal laughter and seemingly committing horrible crimes on a whim.
Behind the mask hides a tortured human who couldn't find happiness in life and became a witch as a result of the trauma and pain she went through. Who is she and why does she behaves as she does? Without love, you cannot see it.
