Create an anime-style image featuring a character with messy black hair

Create an anime-style image featuring a character with messy black hair, wearing a dark coat with red patterns on it. The character should have intense blue eyes that convey anger and determination, with a menacing expression. The background should be dark, with a subtle glowing outline around the character to emphasize their presence. The overall vibe should be mysterious and intense, similar to Demon Slayer aesthetics, but with blue eyes and a fierce look."
