Dark fantasy anime portrait of a hooded necromancer in flowing black robes, long dark hair spilling from beneath the cowl, a partial skull mask fused to their face with glowing crimson eyes burning from the sockets, cupping a weathered human skull in both hands that radiates its own piercing red eye-glow, standing in a ruined gothic cathedral with a massive shattered stained-glass window behind them blazing with blood-red light, tattered crimson ribbons and cloth strips swirling through the air like living tendrils, a pile of discarded skulls scattered in the shadows to the side, cracked stone walls and dead vines, heavy chiaroscuro lighting with deep blacks and intense red accents, ominous eldritch atmosphere, painterly anime horror aesthetic, hyper-detailed bone texture and fabric, 8k, masterpiece
