The Cold Edge of Lightning. A visceral tribute to Killua Zoldyck’s transition from a loyal friend to a lethal protector. This design captures the moment he taps into his primal instincts, holding a literal heart in his hand while surrounded by the jagged electric aura of his "Godspeed" technique. The muted grey mineral wash emphasizes his haunting silhouette, while the piercing blue eyes serve as a warning: the hunter has become the hunted. For those who move faster than sound and strike with absolute precision.
