Blood type

A muscular man with short brown hair stands shirtless against a rocky cliff under a clear blue sky, his face contorted in a grimace as he looks off to the side, then begins to put on a black jacket. A man in a striped shirt points forward, a hand grips a silver gun, a hand applies dark paint to a bicep, and a man with blonde hair and glasses looks down, all set against outdoor backdrops of rocks and trees.
