Knuckle Duster (ナックルダスター Nakkuru Dasutā) is an attack spell of Subaru Nakajima.

By spinning the Knuckle Spinner, Subaru compresses mana on Revolver Knuckle and gives a punch attack.

The power of this spell can reach the level of blowing away the opponent mage disregarding its barrier and field-type defenses.[1]


  • Knuckle Bunker, one of Ginga's magic-enhanced attack, is likely a variation or enhanced version of Knuckle Duster.
