Ragna the Bloodedge (The Grim Reaper) is a playable character in the BlazBlue series and is the main protagonist of Azure Saga (from BlazBlue Calamity Trigger to BlazBlue Central Fiction). He returns in BlazBlue Cross Tag Battle as a playable character.
A SS-Class criminal hunted by the world-spanning government, the Novis Orbis Librarium. He bears a powerful weapon called the Azure Grimoire. As a child, his orphanage was destroyed in a great fire caused by his younger brother Jin, possessed by the spirit known as Yuuki Terumi, who cut off his right arm and disappeared alongside their younger sister Saya. Ragna survived thanks to the timely intervention of the vampire Rachel Alucard, who grafted the Azure Grimoire into his new arm. After undergoing training under the legendary hero Jubei, Ragna set out to use his power to destroy the N.O.L. in revenge. His arrival in the 13th Hierarchical City of Kagutsuchi has led to a chain of events which threaten the balance of the universe.
In battle, Ragna uses the Azure Grimore's Soul Eater ability to devour the souls of his opponents. He also uses the Blood-Scythe, a short but bulky sword which can also take the form of a scythe as its name implies.
