Ragna the Bloodedge is a wanted criminal with an extraordinarily large bounty on his head (well in the trillions) for attempting to destroy the Novus Orbis Librarium, and is Jin and Saya's older brother.

In December AD 2199, several years after the Second War of Magic, a branch of the NOL was utterly destroyed by an SS-class rebel named "Ragna" also known as the "Grim Reaper", in an attempt to destroy the Librarium. The NOL, hoping to stop him, immediately announced the largest bounty ever, available to anyone who could capture him. Interestingly, Ragna possesses a powerful form of Ars Magus known as the "Azure Grimoire." This led the NOL, as well as the other fighters, to hunt Ragna not just for his bounty, but also his Azure Grimoire.
