Black and white vertical tattoo design of an aggressive Oni mask in traditional Japanese style, with large, curved bull-like horns. The Oni's face has fierce, exaggerated expressions with sharp teeth and wide, intense eyes. Thick, flowing smoke emerges from its snarling mouth, wrapping around the mask and extending upward to form a dynamic background. The design incorporates intricate line work and shading, emphasizing the contrast between the sharp details of the Oni and the soft, billowing smoke. Blackwork style with strong Japanese tattoo influences.
