Pink-Haired Demon Warrior with Sword

Anime-style illustration of a young female demon warrior with long pink hair, blue eyes, and purple horns. She is wearing a revealing red and black outfit with matching gloves and thigh-high boots, and has a black tail. The character is holding a large sword in her raised right hand while her left hand is clenched in a fist. The background features a medieval castle with towers under a full moon, with bats flying in the night sky. The scene has a dramatic fantasy atmosphere with dark colors contrasted against the bright moon.

This appears to be an original anime/manga-style illustration, likely created as character art for a fantasy-themed work. The detailed art style suggests it could be promotional artwork for a light novel, manga, or anime series, though the specific source is not identifiable from the image alone. The illustration demonstrates typical characteristics of Japanese anime fantasy art, including exaggerated features, vibrant colors, and dramatic posing.
