Video prompt: Shonen anime style 4K UHD video, 12s, 60fps, loopable, wide shot, vertical composition, brave anime boy with short black hair, sharp brown eyes, determined expression. Wearing black samurai armor with red dragon family crest, white haori, katana with cherry blossom-engraved tsuka. Standing in dense anime-style bamboo forest: tall bamboo stalks swaying, narrow stone path, dappled sunlight, faint mist, bold lines, dynamic shading, vibrant colors. Dynamic actions: He slowly draws his katana with a smooth, deliberate motion, the blade glinting in the sunlight, a fierce look in his eyes; he holds the sword above his head, preparing to strike, then brings it down in a powerful, fluid motion, slicing through a bamboo stalk, which falls to the ground with a loud crack; he sheathes the sword with a soft click, then adjusts his white haori with one hand, his eyes scanning the forest for enemies; he takes a single, deliberate step forward, his boots thudding on the stone path, his hand resting on the hilt of his sword, ready to draw it at a moment’s notice; a bamboo leaf floats past his face, and he flicks it away with his finger, his eyes never leaving the forest. Lighting: Cool natural daylight, dramatic shadows, high contrast, metallic armor texture, sharp sword blade details, no text, no watermark. Style: Shonen anime, action, adventure aesthetic. --ar 9:16 (Vertical, 1080x1920, YouTube Shorts Standard)
