Black Alice

Alipheese 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.

Biography
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 Shinohebi 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.

At the end of Chapter 2, after Luka rebels against Ilias, the goddess orders Black Alice to lead the reorganization of the world; the former Monster Lord will crush any human as well as any weak, unfaithful monster that stands in her way, selecting pure, powerful monsters for the next generation.

Trivia

 * Black Alice strongly resembles the Alice from Alice in Wonderland.
 * With Alice the XV (Fifteenth) and Alice the XVI (Sixteenth) being Alice the VIII’s descendants, it is possible that Black Alice has a Lamia form.
 * Due to variances in the translation, there are different versions of her full name, including Alipheese and Alicefeeze.
 * According to Tamamo, Black Alice strayed from her initial path of being a monster lord much in vein of Alice currently. This was because of an "incident" which made her hate all humans.  What this incident is, is yet to be revealed.
