月下动漫长枪武者

Create a cinematic anime action scene at night in an ancient East Asian palace courtyard. A lone martial warrior, {argument name="character name" default="unnamed spear warrior"}, is midair above a stone arched bridge, performing an acrobatic spinning attack while holding a long silver spear with a sharp double-edged spearhead. The warrior wears flowing dark navy and white robes with silver armor accents, long trailing sashes, and dark hair partly hidden by a hood or head covering; their body is inverted in a dynamic flip, face partly visible, emphasizing speed and skill. A bright cyan-blue energy arc from the spear sweeps across the lower right foreground in a huge crescent slash, scattering sparks, debris, mist, and motion streaks. The setting includes exactly one main stone bridge with dark wooden railings in the foreground, one smaller bridge section behind it, traditional tiled palace buildings with warm lantern lights, distant jagged mountains, pine trees on both sides, and a large full moon glowing through drifting clouds in a starry deep-blue sky. Use dramatic moonlit lighting, cool blue shadows contrasted with warm amber windows, detailed anime key art style, sharp linework, atmospheric fog, high motion blur at the edges, and a wide 16:9 composition like a fantasy wuxia animation still. No text, no watermark, no modern objects.
