Belvaac

Double-Bladed Axe: Belvaac is an axe Teigu that can only be wielded by someone with a very high strength. It was formerly owned by Daidara and is currently owned by the Revolutionary Army.

Abilities
It contains a tremendous amount of offensive power. It looks like a double-edged axe, and it can be separated into two axes that can be thrown and will pursue the target until it hits.

Background
While searching for a compatible weapon, Belvaac was one of many Teigus to be displayed by Honest for Esdeath to choose. Esdeath was quite found of the axe, but had decided that it wasn't the perfect weapon she was seeking.

Some time after, Daidara got a hold of the Teigu and used it in many of his battles while fighting alongside his comrades. After his death, the Teigu was repossessed by the Revolutionary Army.

In the anime, one of the revolutionary soldiers used it in a battle against Esdeath shortly before being killed with the woman's ice power.
