Demon Sword

Demon Swords (魔剣) are special swords that are infused with demonic magic.

Overview
Demon Swords are crafted by demon forgers, by using specialized metals which are infused with magic. Unlike holy swords, which all contain great magic power, demon swords can vary in quality that can range from those with weak magic power and those with great magic power.

Each demon sword has its own source, with the sword being very selective in choosing its wielder. A person who isn't deemed worthy by the sword can't even wield it, as the sword will refuse to allow to even lift it. And if an unworthy would-be-wielder persists in trying to pick up the sword, the sword will lash out in various ways, such as draining their magic power. A demon must prove their worth to the demon sword by subjugating it with their own power. A demon sword will only acknowledge an owner who is powerful enough to subjugate it but also treats the demon sword with respect and care.

Despite the durability of demon swords, it is possible to break them. However, unless the source of the sword is destroyed, the sword will regenerate, which the wielder can speed up by pouring their own magic power to accelerate the recovery process.

Abilities
All demon swords possess great sharpness and durability, being able to break ordinary weapons with a single hit, regardless of what material they are forged from, as well fight against other magic weapons. Though the true worth of the weapons is dependant on its wielder, as slashing ability and strength is based on how much of the sword's potential its user can draw out.

However, some powerful demon swords may inflict some kind of negative status effect upon its wielder in exchange for its power.

Certain powerful demon swords also possess a unique power that only that specific sword can accomplish. This can range from manipulating various elemental forces to weakening the opponent with a cursing effect.
