Moonblade Ronin

A dark samurai fantasy design featuring an undead skeletal warrior standing beneath a massive full moon marked with glowing white rune-like lines. The skeleton ronin wears torn battle robes and worn armor while holding dual swords in a dramatic, upward pose. Black ravens circle through the moonlit sky, surrounded by twisted dead trees, drifting bones, smoke, and floating debris. The overall look feels haunted, cinematic, and powerful, blending Japanese warrior energy with gothic death-moon imagery.
