The Blood-Scythe is the weapon of Ragna the Bloodedge.

In its sealed form, it takes the form of a sword that slowly devours the opponent's soul upon contact. The weapon in its awakened form takes the form of a scythe with a crimson energy blade that seems to be made out of seithr.

The original owner of the Blood-Scythe is Bloodedge. Celica received the weapon after his death. Nearly 100 years later, Ragna would inherit the sword from Jubei, who found it in the rubble of the burnt church.

Trivia

 * In early concept designs, the Blood-Scythe was identical in design to the swords that float around Mu-12, Lambda-11 and Nu-13.
 * Since Bloodedge had possession of the sword because Ragna brought it with him from the future, and Ragna had possession of it by inheriting it from Bloodedge, the Blood-Scythe and their coat technically have no point of origin, and are, therefore, paradoxes. They are also technically unbreakable, or at least remarkably durable.
