Ragna the Bloodedge

After destroying countless branches of the NOL and killing two Saya replicas, he was labeled as the most wanted criminal and received the largest bounty in NOL history on his head. He possesses a powerful form of Armagus called the Azure Grimoire, which is often either the secondary or primary target of those after his bounty. His ultimate goal is to destroy the Library for reasons unknown, although it probably has something to do with the Saya replicas.

He is Jin's biological brother, whose rivalry with him stems from an incident that happened with their sister, Saya, who is presumed to be dead. His right arm is mechanical because his real one was cut off by Terumi who took control of Jin's mind. He was resurrected by Rachel as a vampire, causing one of his green eyes to turn red, and his once blond hair to white. The Azure Grimoire he possesses is only a fragment of an imitation, and the real Grimoire is actually destined to be wielded by Noel Vermillion. During the events of Continuum Shift, Ragna has taken Noel into his care, and starts caring for her much like he did with his sister Saya.
