Code Geass: Nina Einstein

Actually, Nina is the one I hate most in this anime.
But, since someone request about her.. I will grant his request..
There she goes..

Nina Einstein (ニーナ・アインシュタイン, Nīna Ainshutain)

Voiced by: Saeko Chiba (Japanese), Kim Mai Guest (English)

• Age: 17
• Zodiac Sign: Virgo
• Blood Type: A

One of the members of the Student Council. She is usually on a computer or reading. Nina has a fear of Elevens and was initially intimidated by Suzaku having joined the Student Council, but seems to have warmed up to him. She is also researching the possibilities of Uranium-235 as a fuel. She develops an intense crush on Princess Euphemia after the princess shifted a soldier's attention from Nina to herself during the Lake Kawaguchi Convention Center Hotel incident. Upon discovering Euphemia's death, Nina becomes emotionally unstable and begins working to modify the Ganymede Knightmare Frame and to equip it with a prototype nuclear weapon to try and inflict revenge upon Zero. During the siege at the end of the series, she has managed to halt any conflict at the school due to her possession of a prototype sakuradite enhanced nuclear weapon and the fact it appears she has mentally snapped.

This is where Nina meet Euphemia Li Britannia for the first time.

Apart from masturbating at school over magazines, Nina’s hobbies include computers, following Milly around like a lost sheep.. what a hobby.. -_-"

C.C. from Code Geass

C.C (シー・ツー, Shī Tsū) (also known as C2) is one of the central characters in the Code Geass: Lelouch of the Rebellion anime series by Sunrise. Her Japanese seiyuu is Yukana while she is voiced by Kate Higgins in the English dub.

* Nickname: "Gray Witch"
* Age: 16 (on the surface)
* Height: 160 cm (5'3")

A mysterious green-haired girl who bestows the power of Geass upon Lelouch under the condition that he would grant her greatest wish. C.C. passively oversees Lelouch's missions to ensure that he doesn't die, which would implicate her situation greatly. She dies from a bullet wound to her head in the first episode but later revives and shows up alive at the Lamperouge residence, where she acquaints herself with Nunnally, who initially mistakes her for Lelouch's girlfriend. She was apparently part of Britannia's experimentations in the past, and although she appears to be in her teens, C.C. is apparently much older than she seems. In the opening sequence of the first episode, she is seen observing Suzaku and Lelouch when they were both children. Her name is pronounced as C-two. When by herself, she sometimes communicates with an unrevealed entity(s) via electromagnetic waves.
