Wind-Swept Swordsman Beneath the Moon

Anime digital illustration of a young man standing in a grassy field, holding a European longsword resting tip-down. He has windswept black hair, wearing an oversized black trench coat over a white high-collared dress shirt, dark trousers, cross earrings, and hand tattoos. A long coat tail flows dynamically to the side in the wind. The background features a vast green field leading to a body of water, a pale full moon in a daytime sky, and birds flying overhead.
