Demon-Dweller Sword

The Demon-Dweller Sword (宿魔の剣) is an ancient Anti Magic Weapon.

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.

The sword has black markings on the blade and is mostly covered in dirt. The sword also has a four-sided hilt which is heavily ornamented, a grip with spiral design, and a sphere at the pommel. The sword is capable of cutting magic with its edges and absorbing other people's magical power. However, when it is used to cut anything else, it is reduced to a blunt sword that uses blunt trauma to inflict damage on the opponent.

The sword's original ability is to absorb spells and then to release that magic in a flying slash. After the sword has absorbed a certain amount of magical power, the black markings on it start glowing. At that moment, when the user swings the sword, it unleashes magic with similar elemental properties as the absorbed mage's elemental affinity.

It has been noted that the sword passively absorbs any magic in the vicinity, including the user's, and is immensely heavy. These two factors make it a weapon that only those with no magic power or overwhelming magic power could hope to wield effectively.
