Oldrin Zevon

Oldrin Zevon is the female protagonist of Code Geass: Oz the Reflection (manga). She serves as the head knight of the Britannian Military's anti-terrorism unit, the "Glinda Knights", which was formed to counter the terrorism that began to occur in greater frequency after the Black Rebellion ended in Area 11. She is good friends with the group's leader, 88th Imperial Princess Marrybell mel Britannia, whom Oldrin has known since childhood.

Appearance
Oldrin Zevon has blond hair that is kept in at least one ponytail and green eyes. Before O2, she is often shown either in a very revealing pilot suit or a unique uniform that consists of a buttoned sleeveless shirt, a long-sleeved jacket, and a black and red corset and skirt combination worn over a short white skirt. Oldrin also wears a military officer-style cap when wearing this unique outfit.

In O2, she wears a different outfit that consists of long pants and what appears to be a modified long-sleeved shirt and corset combination.

Code Geass: Oz the Reflection
She was born into the noble Zevon family, but left and joined the military when the family was about to be taken over by her uncle Oiaguro. As a traditional noble, she has a lot of noble pride, but she is also a hard-worker. It is thanks to her hard work that she can serve as the pilot of the Knightmare Frame, Lancelot Grail, a mass-production prototype that is too difficult for ordinary people to pilot.

She is conflicted between her aristocratic belief that “the people should be protected” and her duty of suppressing terrorism caused by those very people. However, her conviction to “protect the smiling faces of the weak” is enough of a reason for her to fight. Her goal is to become a "true knight".

After her disappearance, she is now going to a school called Pendleton School of Madrid, and  now wears an odalisque. She also pilots a custom of the Akatsuki called the Amanecer.
