In a ruined shrine courtyard unde

In a ruined shrine courtyard under a full moon, captured from a side-view angle, a shrine maiden with long dark hair confronts a towering shadowy yokai. The maiden is positioned on the left in a medium shot, holding her katana horizontally in a defensive stance with both hands, her expression intense and focused. She wears a traditional white shrine maiden top, red obi, and dark hakama while red maple leaves swirl around her feet. Looming above from the right side, the yokai is an immense, dark, insubstantial silhouette with glowing yellow eyes. Brilliant blue spiritual energy forms swirling patterns around the maiden's katana blade, emitting a cold light that illuminates her face and the leaves below. Small glowing talismans float in the space between them. The dilapidated wooden shrine walls stand in the background, partially obscured by fog. The overall atmosphere is eerie and tense, with a high-contrast palette of deep blacks and reds contrasted by the cold blue light.
