He is able to invoke Destruction daggers to help him in combat, and he is able to gain more power by battling opponents.

Destruction Daggers: He is able to summon up to four daggers out of Destruction for combat.   Twisted Nichirin Katana: H carries around a heavily modified Nichirin katana similar in appearance to an Indonesian Kris Sword, with the blade's shape modeled into waves resembling a slithering snake. It is dark gery in color. His katana's tsuba has a gold circular shape engraved with two snakes connected by several plant-like patterns. His handle is light blue and decorated with a twisting wrap of magenta cord. The words Destroyer of Demons (惡鬼滅殺 Akki Messatsu?) are engraved on the side of the blade. H also carries along a special scabbard made of leather held together by a weak magnetic pull that opens up whenever he uses his katana.
