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.

As an example of its ability, if someone was affected by poisonous magic, other Anti Magic swords would by able to get rid of the poison, but would be powerless to cure the harm that the poison has already done. Alternatively, the Demon-Destroyer Sword would be able to cure the poisons effects. This ability is even strong enough to negate Reincarnation Magic.
