Alice

Alice is the Master of Caster in Fate/Extra.

Appearance
Alice is young girl with doll-like limbs and light pink eyes. Her long, pure white hair is divided in to braided pigtails that are tied off with a white and blue ribbon for each. Alice's clothing consists of a white hat that has a blue ribbon on each side, a light blue victorian-style dress and black shoes. The dress is trimmed with white lace and decorated with two ribbons; one around her neck and the other tied around her waist.

Personality
Alice is a bright, playful child and also very shy. She is desperate for friends and people to care for her. Because of her innocent nature, she never recognizes the fact she is in a war and never acknowledges the harm of "playing" in battle with her peers.

Role
Alice is the third Master the Protagonist faces during the Holy Grail War, although she is first introduced as a ghost haunting the 3rd floor of the school during the prologue. Alice and her Servant (who also refers to herself as Alice) appear to be identical twins, even dressing in the same style of clothing.

Throughout the week, they convince the Protagonist to play games with them, some of which are detrimental to the hero's health. On the first floor of the arena, Alice and Alice summon a monster that is initially believed to be a Berserker class Servant. After the "Servant" is defeated by a newly created Vorpal Blade only Alice and Alice remain. It is then deduced that the monster was not the children's companion at all On the second floor of the arena, the two girls change the area around them in to a place where all intruders forget who they are over time, eventually dying. When the Protagonist survives this encounter the first time, it is revealed a powerful Reality Marble has been put in place. The hero is able to diffuse the area of effect by saying their name out loud. It is this, and helpful advice from Touko Aozaki, that imply Alice's servant is of the Caster class and is actually the second Alice.

It is revealed soon after that Alice's Servant is Nursery Rhyme, the embodiment of the world of picture books for children. Because Nursery Rhyme does not have its own body, it manifests itself as the will of its current Master; in this case a mirror version of Alice herself, who wished for a friend to ease her loneliness.

In Alice's final moments, she confirms what had been insinuated the entire time: Alice is already dead in the real world. However, her spirit is able to live on in the Moon Cell as a "cyber ghost". As she and Caster lay dying, Alice held her Servant's hand and told her it's would be okay. With a final smile, she disappeared.
