Alice (アリス, Arisu) is a tomboyish girl who is Nunnally's best friend and classmate in the spin-off manga Nightmare of Nunnally. She is very caring and will protect Nunnally if she is in trouble. In reality, she is secretly an agent of the Irregulars assigned to the surveillance of Milly Ashford under the cover identity of a middle school student. Nunnally reminds Alice of her deceased paraplegic little sister whom she couldn't save during a fire. Her relationship with Nunnally can be compared to that of Lelouch and Suzaku in the anime. After the final battle with the Eden Vital she cuts her hair short and becomes Nunnally's Knight. As a result of the battle, she has also lost her Geass. She is last seen helping at Ashford Academy after it has been made into a refugee camp, alongside former Irregulars.
Alice's normal physical abilities have been augmented with cells originating from C.C., giving her a Geass ability called "The Speed," which allows her to hyper-accelerate all objects within a given radius by manipulating gravitational pull. Designated by her unit to pilot a Knightmare Frame customized to exploit this ability, Alice serves as a highly effective point man on the field of battle. When her ability is active, a Geass sigil appears on her forehead. Alice's blood contains a chemical suppressant that minimizes the activity of C.C.'s biological matter, which has a tendency to strain and overtax the human body. A neutralizer for the suppressant may be administered to temporarily boost the effect of "The Speed" in battle, enabling movement of sufficiently high speed that it resembles teleportation. Her skill with the Geass is so great that even Lelouch and C.C. are impressed by it. C.C.'s cells in her body also gives Alice extremely high resilience and regeneration, thus she is able to easily survive and regenerate from being fatally shot as well as falling several stories after being pushed of the top of the Lake Kawaguchi Hotel. As a Britannian soldier and special agent, Alice is well trained in various related fields including espionage and computer hacking She is more than efficient with the use of firearms. She is also very athletic and skilled in martial arts.
Alice pilots a standard Irregulars Knightmare Frame for most of the series. When she makes her Geass contact with Magical Device Nemo, she pilots a modified version of the Mark Nemo called the Code Geass against Cardinal Rolo vi Britannia. It is quickly destroyed though, only to reveal a new and more powerful Knightmare underneath.
It is revealed in Chapter 16 that her three size is as follow;
- Breast: 78
- Waist: 61
- Hips: 76
