Third Alice

The First "Alice" is a character from the Vocaloid song "Alice of Human Sacrifice", performed by MEIKO, KAITO, Miku Hatsune, Len Kagamine, and Rin Kagamine. She is the Wonderland Dream's third known victim and a cruel monarch within that world.

She was voiced and portrayed by Miku Hatsune, who also portrayed the Rotten Girl.

History
It all began when the dream that would later become known as Wonderland decided to live forever by possessing humans and making them dream it forever, causing the dreamer to eventually die and loose their mind in the dream, where it would trap it and use it as an aspect of its ever-evolving world.

After taking the lives of two other victims, the dream came to the third "Alice", likely ensnaring in her sleep. In this dream world, she was a beautiful and powerful girl, but was egotistical, power hungry, and selfish. Using her breathtaking beauty, she wooed the inhabitants of Wonderland into raising her up as their leader. She has them build a castle and kingdom for her, naming herself the queen of the land.

However, she was constantly afraid of losing her beauty, as it was the only thing keeping her in power and was the only thing that truly mattered to her. She feared illness, age, and death, and saw them as marks against her perfect body. She obsesses over this subject for so long and so hard that she eventually becomes lost in it, her mind being broken and slips into a permanent state of madness. Her mind was permanently trapped in the dream as she died in real life.

Aspects of her existence were worked into Wonderland's world, including the implementation of a strict monarchy, the obsession with youth and beauty, and perhaps even incorporating her into the Queen of Hearts.

Despite this, when the fourth "Alice" (which is actually an innocent pair of twins) arrive, they receive an invitation to the castle. This could be the posthumous mental remains of the third "Alice", luring them closer to their demise.

Personality
The third "Alice" is egotistical and selfish, and only cares for her own stature and beauty. She uses her beguiling charm and looks to seduce and persuade, as she knows it is her greatest asset. She is hungry for power and status, and desires to be the highest ruler of the land and remain that way for all time, fearing the inevitability of age and death.
