Nonette Enneagram

Nonette Enneagram (ノネット・エニアグラム, Nonetto Eniaguramu) is a member of the Knights of the Round as the Knight of Nine.

Character Outline
She attended military school with Second Princess Cornelia, who considers Nonette her senior. An upbeat and cheerful woman, she is one of the few people Cornelia actually fears. Her first and last names contain the Latin and Greek prefixes for 9, non- and ennea- respectively. Her last name is may also be a reference to the Enneagram of Personality. She first appears in the PSP/PS2 video game, Code Geass: Lost Colors and serve as some sort of mentor or older sister figure to the Protagonist if the player decide to choose the Britannian Military route, she is also always seen carrying a pistol with her. It is never shown whether she had ever actually used it, but given her military background, she must have had some proficiency with it. Out of all the Knights of the Round, she is the only one who has no speaking role in the anime and the only one seen without a Knightmare Frame of her own.

Character History
She is briefly seen when all the Knights of the Rounds make their first appearance together. She is later seen when Lelouch makes his ascention to the throne along with Suzaku. It is unknown what happened to Nonette following Lelouch's ascention to the throne, as she does not reappear and is not referenced to either.
