Aeros Issue 1

Due to fear of retailiation from Heaven, the blade was forged by Satan and Avenges. Due to it's power, it was given to the strongest demon solider, Aeros.

Aeros Issue 2

After a battle between Aeros and his brother, Panteris, it was split into two weaker blades, the Sword of the Unholy and the Sword of Vengeance. 

Project Point Issue 1-2

While it was never the focus of any issue, the seperated blades were used by Jvukaro in combat.

Physical Appearance

The Blade of Beelzebub is a large sword split diagonally down the middle. One side is Vantablack and in some modern artwork it even produces a sticky, black substance. The other side is pure white, typically having 1 eye towards the center of the full blade, some artwork also depicts additional teeth.

When separated, they both appear as regular longswords, however both retain the colors of both respective sides while losing the additional details.

• The original names for the separated swords were the blade of unholy darkness and the katana of vengeance.

• It has never been seen fused together during Project Point.
