Anime Necromancer in a Haunted Mansion

Anime-style necromancer in a haunted mansion: a slender figure in midnight-black robes trimmed with bone runes, long dark hair, pale skin, and glowing violet eyes. They stand in a creaking corridor, raising a staff topped with a skull as blue-violet necromantic energy swirls around, skeletal hands clawing up from cracked floorboards and translucent spirits rising into the air. The haunted house is Gothic and decayed: peeling wallpaper, cobwebs, torn velvet drapes, a broken chandelier, and a dusty piano. Moonlight streams through a shattered window, casting cold blue and purple light and dust motes in the air. The art style is crisp anime cel shading with a dynamic pose, bold outlines, and dramatic lighting; high-detail textures on lace, bone motifs, and glowing runes. Floating orbs and watchful portraits in the background heighten the eerie atmosphere.
