Alice XV

Alipheese Fateburn XV (Fifteenth) was the previous Monster Lord and the mother of Alice XVI (Sixteenth). Much like Luka, she had dreams of coexistence between monsters and humans, however believing that monsters and humans were fated to fight one another, the only way she could see to bring that coexistence was to sacrifice herself in the hope that humanity would carry on her wishes. During her Monster Lord ceremony, she battled Cassandra, the only other challenger, for the right to become the Monster Lord.

Alice XV is not directly seen in the game, however she is depicted as a Lamia, sharing a silhouette with her daughter. Like many generations before her, Tamamo was her instructor although not much else is known about her.

Biography
When her castle was invaded by Marcellus, Lazarus, Merlin and Karen, Alice XV went to confront them them, having locked up her daughter in a magic-reinforced prison cell to prevent her from following and to preserve her for the next generation. Tamamo tries to stop Alice XV, to no avail; Alice XV uses her powers to make her fall  asleep.

After a battle between the hero group and herself, Marcellus then kills her, but the party is not satisfied; they had just realized her intentions and all begin to repent their actions. Interestingly, Alice XV seemed to give no hint of relenting to the heroes beforehand, seeing the battle as a necessity.

As the heroes begin to grieve the Monster Lord’s death and carry on her wishes, Alice XVI comes in, an outcome unforeseen by the late Monster Lord and somewhat causing her plan to backfire; Alice XV had underestimated her young daughter’s power and how strong the cell would have to be. Noticing her mother’s death, her daughter goes out on blind rage against the human party, killing Merlin and Karen, unintentionally ruining her mother's plan.

Killing Karen, the woman they both loved, Marcellus and Lazarus went back on their earlier grief and became the founders of Ilias Kreuz.

Alice XV’s death also sparked the next competition for the heir to the title on Monster Lord, leading to her own daughter and original heir to battle against those who would later become the Four Heavenly Knights in the first battle royale in the competition’s history.

Since Alice XV’s death, Alice XVI was fixated that she must die in order to avenge her mother. Luka responds that she was simply a miscalculation that shattered her mother’s plans in mere seconds.
