While you control no other monsters, this card can attack your opponent directly. Once per turn, when an opponent's monster declares an attack: You can detach 1 Xyz Material from this card; immediately after this effect resolves, this card declares an attack (the Battle Step and Damage Step for both attacks occur simultaneously). This card must be in face-up Attack Position to activate and resolve this effect.
