Void Sword

The Void Sword is a sword that was stolen from a museum by Brian to use in the battle with Chris at the end of Hospital Boarding.

During the battle, the sword was embedded in Chris's shoulder after a failed decapitation by Brian. Chris then removed the sword from his shoulder and used his Void powers to enhance the blade's power and durability.

Unbeknonwst to the group, Chris used his final moments before he disintegrated to transfer his soul and consciousness into the blade.

At the end of the Hospital Boarding Arc, Brian buried the Void Sword in the middle of nowhere in the Siberian wilderness.
