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 owner of the Blood-Scythe has always been Ragna the Bloodedge. When Rachel Alucard sent Ragna back in time to the First War of Ars Magus during the events of BlazBlue: Chronophantasma, Ragna used the weapon but left it behind before he was summoned back to his current timeline. Celica A. Mercury later received the weapon after Bloodedge's apparent '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.
 * Because Ragna left behind Blood-Scythe and his coat when he was transported back to his current timeline in the events of BlazBlue: Chronophantasma, its unknown how he had the sword and jacket later on in the events of said game. Because of this, the two items are to be considered paradoxes.
