A dark fantasy anime-style cover with black and white colors, featuring the Grim Reaper as an epic warrior in full battle armor, surrounded by swirling clouds and lightning. He has long hair flowing behind his head, and the background is dark with light rays of lightning shining through the stormy sky. He wears a cloak that flows around him like shadows. The overall mood should be dramatic and powerful, with elements of darkness and power. --ar 9:16 --s 50
