Demon-Destroyer Sword

The Demon-Destroyer Sword (滅魔の剣) is an ancient Anti Magic Weapon. The sword is found within the central room of the Gravito Rock Zone's floating dungeon.

Description
The sword is summoned out of an opened grimoire, inside which it is stored in the form of writing. The user can easily summon the sword at will without consuming any magical power.

As well as cutting through magic and spells with its edges, the sword has a special ability, Causality Break (因果解放). It absorbs and removes the effects of spells by severing the cause-and-effect relationship. It emanates tendrils of Anti Magic that touch those affected by magic and absorb the magic and its effects. The Anti Magic then draws back into the sword, turning the blade black. This ability is strong enough to negate Reincarnation Magic.
