Orpheus Zevon

Orpheus Zevon is the male protagonist of Code Geass: Oz the Reflection (photo story). Originally born into the Zevon noble family along with his twin sister Oldrin, he now works as a mercenary terrorist under the codename "Oz", receiving and acting on requests across the world from the organization "Peace Mark" that controls and sends out terrorists. He does so for the sake of chasing and achieving revenge against the enemy that took his beloved person away. He does not care who the client is or the reasons for the mission request; he will simply carry it out as specified. Perhaps because of the environment he grew up in, he has a lot of rough behaviour, but sometimes he shows his original aristocratic side. He possesses a Geass in his left eye.

Orpheus was originally born into the Zevon noble family in Britannia along with his twin sister Oldrin. However, because of the Zevon family tradition of succeeding through the female line and, in the cases of twins, removing the male child from the family, he was thrown away and adopted by a commoner family at a very young age, with little to no knowledge of his birth and family.
Soon after, however, he was taken in by the Geass Order, and was given the "Geass of Transformation" by V.V. there. Thereafter, he spent an unknown number of years within the Order, where he was forced to serve as an experimental specimen and develop his Geass. The only thing that let Orpheus endure these "hellish" days was Euria, a fellow Geass-user he met within the Order and fell in love with.

He is voiced by Tatsuhisa Suzuki in Drama CD.
