Animate the provided first frame into a 15-second original AI anime shonen fantasy video in 16:9 widescreen. Keep the same two characters, same ruined mountain shrine, same sunset sky, same celestial serpent, same outfits, same powers, same lighting, and same cinematic anime style throughout the entire video. STYLE: High-budget modern anime, shonen fantasy masterpiece tone, cinematic trailer pacing, painterly cel animation, crisp line art, dramatic lighting, sakuga-inspired action, hand-painted backgrounds, glowing particles, wind-blown hair and fabric, expressive close-ups, emotional atmosphere. The animation should feel epic, poetic, and powerful, not comedic. CHARACTER LOCK: Exactly two human characters appear in the entire video. REN: Ren is always the young male swordsman. He has messy black hair with subtle blue highlights, dark eyes, a small scar under his left eye, a red scarf, dark navy torn haori, white inner shirt, wrapped forearms, black pants, shin guards, sandals, and a blue-glowing katana. Ren’s power is blue sword energy. Ren moves with grounded courage and explosive sword action. MIRA: Mira is always the young celestial girl. She has long silver-white hair, amber-gold eyes, white and pale lavender shrine robes, translucent ribbon sleeves, golden ornaments, floating paper charms, and golden spiritual light. Mira’s power is golden talisman magic. Mira moves calmly and gracefully, supporting Ren from the shrine platform. Do not swap their roles, outfits, powers, hair colors, genders, weapons, or positions. Ren never uses golden talisman magic. Mira never uses the katana. No extra heroes, no third human character, no crowd. TIMELINE: 0–1.5s: Begin exactly from the first frame. Hold the epic pre-battle composition for a brief cinematic beat. Wind blows Ren’s red scarf and Mira’s ribbon sleeves. Red leaves drift across the foreground. The serpent’s eyes glow faintly in the storm clouds above. 1.5–3s: The sky crack widens. Blue-white lightning illuminates the serpent’s scales. Ren tightens his grip on the katana. Mira’s golden charms begin to lift and rotate around her. Camera slowly pushes in from a low angle. 3–4.5s: Cut to Ren close-up. His black hair whips across his face. He draws the katana, and blue light runs along the blade. His expression changes from pain to determination. 4.5–6s: Cut to Mira medium shot. She raises one hand calmly. Golden talismans unfold around her like small glowing birds. Her amber eyes reflect the serpent in the sky. 6–7.5s: Wide action shot. The serpent releases a shockwave through the shrine. Lanterns flicker, dust rises, leaves spiral, broken stones tremble. Ren lowers his stance and prepares to charge. 7.5–9s: Ren sprints up the cracked shrine steps. Camera tracks low beside him. His red scarf streams behind him. Mira sends golden talismans forward, creating glowing stepping platforms in the air. 9–10.5s: Ren leaps upward from the first golden platform to the next. His katana leaves a blue arc through the air. The camera tilts upward to reveal the enormous serpent above him. 10.5–12s: The serpent strikes with lightning. Ren blocks midair with the blue katana. Blue sparks explode outward. Mira below holds both hands forward, maintaining the golden charm path. 12–13.5s: Mira releases a spiral of golden talismans. They wrap around Ren’s blue sword trail and form a huge circular seal pattern in the sky. Camera briefly orbits around the glowing seal. 13.5–15s: Final climax shot. Ren raises the katana in midair while Mira stands below with robes and hair flowing. Blue sword energy and golden talisman light combine, freezing the celestial serpent inside a massive seal above the broken torii gate. The storm clouds part, sunset light floods the shrine, and red leaves drift peacefully. End on a powerful final anime hero frame. CAMERA: Use cinematic anime camera language: low-angle hero shot, emotional close-ups, wide scale reveal, fast but readable action tracking, upward tilt, brief orbit around the seal, final pullback hero frame. Avoid chaotic cutting. Keep action readable. MOTION: Ren’s motion is sharp, athletic, and explosive: draw sword, sprint, leap, block, raise blade. Mira’s motion is graceful and controlled: raise hand, summon charms, sustain magic path, release seal. The serpent’s motion is massive and slow: clouds coil, eyes glow, lightning strikes, body freezes inside the seal. Hair, scarves, robes, leaves, dust, talismans, lightning, and glowing particles should have natural secondary motion. LIGHTING: Warm sunset backlight, blue lightning flashes, golden talisman glow, blue sword rim light, lantern flicker, dramatic clouds. Faces must remain clear and expressive. ENDING REQUIREMENT: The final frame must clearly show Ren in midair with the blue-glowing katana, Mira below with golden talismans, and the celestial serpent trapped inside a blue-gold seal over the ruined shrine. The ending should feel like the climax of a masterpiece anime trailer.
