Oldrin Zevon is the main character in Code Geass Oz the Reflection manga series. She serves as the leader of Britannia's anti-terrorism unit, known as the Glinda Knights, which was established after an increase in terrorist activities following the end of the Black Rebellion in Area 11. Born into a noble family, Oldrin left to join the military when her uncle threatened to take over the family. Despite being from a privileged background, she is hardworking and has become proficient at piloting the Knightmare Frame Lancelot Grail, an advanced prototype that is difficult for ordinary individuals to operate. She struggles with conflicting beliefs - on one hand, she believes in protecting the weak; on the other, her duty requires her to suppress terrorism caused by those very people. However, her conviction to protect "smiling faces" drives her to fight and become a true knight.
