Black Alice

Alicepheese the VIII (Eighth), also known as Black Alice, is one of the main antagonists of the game. During her reign as Monster Lord, she attempted to take over the world. Supposedly defeated by Heinrich 500 years ago, she was kept alive by Ilias. In order to keep Black Alice in line, Ilias threatens to kill her if she makes any action which may go against Ilias's cause.

Lilith & Lilim mentions that Black Alice entrusted them to lead the Succubi to a haven for their own race.

The Queen Elf mentions that Black Alice manipulated her and the Queen Fairy into kidnapping Sara to deal with Sabasa.

Black Alice herself appears to Shinoberi in Yamatai Village, agreeing how humans can be easily used and manipulates. She asks the white snake to join her cause, and tells her not to worry about the current Monster Lord's reign.
