Demons Swords

The Demon Swords (魔剣 Maken) are weapons infused with Demonic power and are considered to be the ultimate weapons against Angels and Fallen Angels.

Summary

Not much is known about the Demon Swords except that they have a strong curse placed on them which brings misfortune to their wielders.

The Sacred Gear Sword Birth has the ability to create Demon Swords, but they are inferior to the original ones.

Abilities

Demon Swords are the exact opposite of the Holy Swords, in which they use demonic power and are extremely powerful against Angels and Fallen Angels. Just as with the Holy Swords, only a select few can wield Demon Swords and they are known to even shorten the lifespan of its user if overused. Demon Swords appear to have a will of their own, as revealed in Volume 12.
