Demon-Slayer Sword

The Demon-Slayer Sword (Danma no Tsurugi) is a magic greatsword in Black Clover and the first sword Asta wields. It was previously wielded by Licht, and it became an Anti Magic Weapon after Licht's grimoire was corrupted and Liebe developed Anti Magic inside the book. The sword is stored as writing inside an open grimoire and can be summoned at will without using any magic power. It is a huge greatsword, mostly covered in dirt and scuff marks, whose edges cut through magic and whose flat side reflects it; against anything that is not magic it works like a blunt sword that does damage through impact, though its tip is still sharp enough to cut.

Tapping someone's head with the crossguard removes mental enchantment. Anti Magic can be pushed out from the edges and condensed into a bigger blade, the basis of the Black Divider, which widens its defence and extends the reach of its attacks, and by controlling the Anti Magic inside it the user can make the sword hover, ride it through the air or send it to attack from a distance.
