I am another you. Another shape of the girl named Nunnally. And from this day on, I will be Princess Nunnally’s knight.


Magical Device Nemo, (魔導器ネモ madouki nemo) usually just called Nemo, is a main character from the spin-off manga Nightmare of Nunnally.


She first appears as a small white doll-like thing with a geass sigil on its face. Upon initiating her contract with Nunnally, she takes on a appearance identical to Nunnally, but with light blond hair, red eye, and a geass symbol on her forehead.


Despite sharing a body, Nemo's personality remains distinct from Nunnally. Nemo claims to be an expression of Nunnally's unconscious anger and hostility. As an extension of Nunally inner darkness, Nemo cares about the same things that she does, becoming extremely angered when it seemed like Lelouch and Alice were killed.

She sees herself as Nunnally's knight and as such, is furiously protective of Nunnally and will protect her from danger when possible, such as when she nearly summoned Mark Nemo when some girls were bullying Nunnally.

Before meeting Nunnally, Nemo sought the darkness in humans hearts, believing that gaining that would allow it to evolve from a mere mud doll into a higher state of being.

While experiencing the memories, Nemo finds some memories blocked by the D.O.M. Hostia system.

Being made from C.C.'s cells, Nemo is capable of bestowing Geass contracts, though she must merge with a host in order to do so.


Nemo's Geass

Nunnally and Nemo's geass allows them to "see the lines of the future", an ability that functions like precognition. It is similar to the geass used by Bismarck Waldstein, except that it is more effective because it tells the entire future instead of just one person's. A red geass sigil lights up in Nemo's left eye while it is activated. When combined with their the Mark Nemo, they are almost unstopable on the battle field, taking someone like Alice and her artificial geass "The Speed" to even contend. The geass apparently takes a large toll on Nunnally's body, because she is seen bedridden after long usage of the geass.

She can also create the knightmare frame Mark Nemo to use in battle, joining herself and Nunnally together in a her body. She is also capable of summoning only small parts of it at a time when not controlling Nunnally's body. Cornelia likens her abilities as a pilot to Marianne the Flash.
