アイデアから本番パイプラインまで：AI アニメ制作をステップバイステップで解説（チュートリアル ＋ プロンプト付き）

1Create a detailed character sheet for two original shonen anime battle characters, 16:9 horizontal layout, clean neutral studio background, high-quality fan-animation style, crisp line art, dynamic cel shading, expressive faces, no text, no labels, no logos.
2Show exactly two characters: KAIRO and RENJI. Keep them clearly separated. Include front view, side view, back view, facial close-up, injured expression, battle-ready expression, and one dynamic action pose for each character.
3KAIRO:
4A young male fighter, late teens, athletic lean build, messy black hair with red tips, sharp amber eyes, small cuts on his cheek, intense determined expression. He wears a torn black sleeveless battle jacket, dark red waist sash, loose charcoal combat pants, wrapped forearms, fingerless gloves, heavy black boots, and a short torn red scarf. His power is crimson flame and black lightning. In action poses, red-black energy wraps around his fists and feet. His silhouette should feel aggressive, fast, and explosive.
5Kairo design rules:
6Kairo is always male. Kairo always has black hair with red tips, amber eyes, torn black sleeveless jacket, red sash, wrapped forearms, black boots, and crimson-black energy. Do not give him white hair, blue energy, long coat, spear, mask, or silver armor.
7RENJI:
8A young male rival fighter, early twenties, tall athletic build, long white hair tied back loosely, icy blue eyes, calm but dangerous expression. He wears a long dark navy coat with torn sleeves, silver shoulder guards, layered black inner clothing, pale blue waist cords, slim combat boots, and a cracked half-mask hanging at one side of his face. His power is blue-white lightning and gravity distortion. In action poses, blue energy arcs from his hands and sword-like energy blade. His silhouette should feel elegant, precise, and overwhelming.
9Renji design rules:
10Renji is always male. Renji always has long white hair, icy blue eyes, navy torn coat, silver shoulder guards, half-mask detail, and blue-white lightning energy. Do not give him black-red hair, red scarf, flame fists, red sash, or bulky armor.
11Art style:
12Modern shonen anime, high-budget fan animation, sakuga key animation look, strong silhouettes, clean readable costume shapes, expressive eyes, cel shading, hand-drawn impact energy, slightly rough animation-line texture, dramatic lighting, no photorealistic CGI, no 3D render.
13Negative prompt:
14extra characters, duplicate characters, merged bodies, swapped outfits, swapped hair colors, Kairo with white hair, Renji with black-red hair, Kairo using blue energy, Renji using red flame, bad anatomy, distorted hands, cropped feet, blurry faces, text, watermark, logo, photorealistic style, 3D render
15📷

1A cinematic first frame for a 15-second original shonen anime fan-animation battle, 16:9 widescreen.
2Scene:
3A destroyed city district at dusk, transformed into a huge circular battle crater. Broken asphalt, shattered concrete slabs, bent streetlights, cracked building walls, drifting smoke, floating dust, sparks, and fragments of glass fill the air. The sky is dark orange near the horizon and deep violet above, with storm clouds swirling from the fighters’ energy. The atmosphere feels like the opening frame of an insane hand-drawn anime fight sequence.
4Characters:
5Exactly two fighters in the frame.
6KAIRO:
7Kairo stands in the lower-left foreground, crouched low with one fist pressed into the cracked ground. He is a young male fighter with messy black hair tipped red, amber eyes, torn black sleeveless battle jacket, dark red waist sash, wrapped forearms, fingerless gloves, charcoal combat pants, black boots, and a short torn red scarf. Crimson flame and black lightning coil around his right arm and across the ground. His expression is furious and focused.
8RENJI:
9Renji floats slightly above the ground in the upper-right mid-ground, calm and composed. He is a tall young male rival with long white hair tied back, icy blue eyes, long dark navy coat with torn sleeves, silver shoulder guards, black layered clothing, pale blue waist cords, slim boots, and a cracked half-mask at the side of his face. Blue-white lightning and gravity distortion ripple around his body. Small pieces of concrete hover near him.
10Composition:
11Dynamic diagonal face-off composition. Kairo is low and grounded in the lower-left, surrounded by red-black energy. Renji is elevated in the upper-right, surrounded by blue-white energy. The broken city crater forms a circular arena between them. Their eyes lock across the frame. The energy colors split the image: crimson-black on Kairo’s side, blue-white on Renji’s side.
12Camera:
13Low dramatic anime camera angle, slightly tilted, 28mm wide lens feeling, strong perspective, intense depth, readable full-body silhouettes, enough space for rapid motion in image-to-video.
14Lighting:
15Orange dusk backlight, red flame glow from Kairo, blue lightning rim light from Renji, smoke haze, sparks, dust particles, high-contrast anime lighting, dramatic but clear faces.
16Style:
17High-intensity shonen anime fan animation, sakuga action keyframe, hand-drawn cel animation, impact-frame energy, rough animated line texture, cinematic composition, explosive motion frozen in a single frame.
18Continuity rules:
19Exactly two fighters only. Kairo is always the black-haired red-energy grounded fighter. Renji is always the white-haired blue-energy airborne rival. Do not swap their hair, outfits, powers, positions, or identities.

1Create a detailed 16-panel storyboard for a 15-second original shonen anime fan-animation battle, 16:9 widescreen. Keep the same two fighters, same ruined city crater, same dusk sky, same red-black and blue-white energy contrast, same high-intensity sakuga animation style across all panels.
2CHARACTER LOCK:
3Kairo is always the black-haired young male fighter with red-tipped hair, torn black sleeveless jacket, red sash, wrapped forearms, black boots, red scarf, and crimson-black flame lightning.
4Renji is always the white-haired rival with navy torn coat, silver shoulder guards, half-mask detail, and blue-white lightning gravity energy.
5Never swap their hair, outfits, powers, positions, or identities.
6Panel 1:
7Wide establishing shot. A ruined city crater at dusk. Kairo crouches in the lower-left foreground with red-black energy around his fist. Renji floats in the upper-right mid-ground with blue-white lightning.
8Panel 2:
9Close-up on Kairo’s eyes. His amber eyes sharpen. Red sparks fly across his face, and his scarf snaps in the wind.
10Panel 3:
11Close-up on Renji. His icy blue eyes remain calm. Floating concrete fragments rotate slowly around him.
12Panel 4:
13Extreme wide shot. The entire crater cracks outward as both fighters release energy. Red and blue light split the frame.
14Panel 5:
15Kairo launches forward from the ground, leaving a crater and a red-black flame trail behind him.
16Panel 6:
17Renji drops from the air with a blue lightning blade forming in his hand. Camera tilts sharply upward.
18Panel 7:
19First collision. Kairo’s flaming fist meets Renji’s blue energy blade. The screen flashes with a black-and-white anime impact frame.
20Panel 8:
21Rapid close-range exchange. Fists, elbows, kicks, and blade arcs blur through the center of the frame with speed lines.
22Panel 9:
23Kairo is knocked backward through a broken wall, debris exploding outward. He twists midair to recover.
24Panel 10:
25Renji appears above him using a gravity step, blue energy bending the air around his boots.
26Panel 11:
27Kairo slams both hands into the ground, sending a wave of red-black flame cracks across the crater floor.
28Panel 12:
29Renji splits the flame wave with a vertical blue lightning slash. The blast divides the smoke in half.
30Panel 13:
31Both fighters sprint toward each other through a storm of debris. Camera tracks between them at ground level.
32Panel 14:
33They leap into the air for the final clash. Kairo’s right fist becomes a red-black comet. Renji’s blade becomes a blue-white lightning crescent.
34Panel 15:
35Final impact. Red and blue energy collide above the crater, forming a huge circular shockwave that bends clouds and throws debris outward.
36Panel 16:
37Final hero frame. Both fighters land on opposite sides of the crater, breathing hard. The sky behind them glows purple-orange, the crater smokes, and red-blue sparks drift silently between them.

1Animate the provided first frame into a 15-second original shonen anime fan-animation battle in 16:9 widescreen. Keep the same two fighters, same ruined city crater, same dusk sky, same outfits, same powers, same red-black versus blue-white energy contrast, and same high-intensity hand-drawn anime style throughout the entire video.
2STYLE:
3High-budget shonen fan animation, extreme sakuga action, hand-drawn cel animation, rough key-animation line texture, impact frames, speed lines, smear frames, explosive debris, dynamic camera angles, emotional close-ups, cinematic lighting, dramatic anime battle pacing. The animation should feel wild, fast, and powerful, but the action must remain readable.
4CHARACTER LOCK:
5Exactly two fighters appear in the entire video.
6KAIRO:
7Kairo is always the grounded red-energy fighter. He has messy black hair with red tips, amber eyes, torn black sleeveless battle jacket, dark red waist sash, wrapped forearms, black combat pants, heavy black boots, and a short torn red scarf. His power is crimson flame and black lightning around his fists and feet.
8RENJI:
9Renji is always the elevated blue-energy rival. He has long white hair tied back, icy blue eyes, a long dark navy torn coat, silver shoulder guards, black layered clothing, pale blue waist cords, slim boots, and a cracked half-mask detail. His power is blue-white lightning, gravity distortion, and a sword-like energy blade.
10Do not swap their roles, outfits, hair colors, powers, or identities. Kairo never uses blue lightning blade energy. Renji never uses red flame fists. No extra characters.
11TIMELINE:
120–1.5s:
13Begin exactly from the first frame. Hold the face-off for a short dramatic beat. Kairo crouches low in the lower-left foreground, red-black energy crawling across the cracked ground. Renji floats in the upper-right, blue lightning flickering around him. Dust and small stones hover in the air.
141.5–3s:
15Close-up montage. Kairo’s amber eyes narrow, red sparks fly across his face. Cut to Renji’s icy blue eyes, calm and cold, as concrete fragments rotate around him. The wind grows stronger.
163–4.5s:
17Kairo explodes forward from the ground, leaving a crater and a red flame trail. The camera whips low beside him, following his sprint through broken asphalt.
184.5–6s:
19Renji drops from above with a blue-white lightning blade forming in his hand. The camera tilts upward as he descends, coat and white hair flowing in slow motion for half a beat.
206–7.5s:
21First impact. Kairo’s flaming fist collides with Renji’s energy blade. Use one dramatic black-and-white anime impact frame, then burst into red and blue sparks. The shockwave pushes smoke and debris outward.
227.5–9s:
23Fast close-range fight exchange. Kairo throws rapid punches and a spinning kick. Renji parries with blue blade arcs and gravity steps. Use speed lines, smear frames, and quick camera snaps, but keep both fighters identifiable.
249–10.5s:
25Renji knocks Kairo backward through a broken concrete wall. Kairo flips midair, drags one hand across the ground, and stops himself with a red-black flame skid.
2610.5–12s:
27Kairo slams both fists into the crater floor. Red-black energy cracks spread outward like lightning through the ground. Renji floats above, then cuts downward with a vertical blue slash that splits the flame wave.
2812–13.5s:
29Both fighters sprint toward each other through debris and smoke. Camera tracks low between them, alternating red light from Kairo’s side and blue light from Renji’s side. The crater and buildings blur into speed lines.
3013.5–15s:
31Final clash. Kairo leaps with a red-black comet fist. Renji descends with a blue-white lightning crescent blade. Their powers collide in midair, creating a huge circular shockwave. End on a final hero frame: both fighters land on opposite sides of the smoking crater, breathing hard, red and blue sparks drifting between them under the orange-violet dusk sky.
32CAMERA:
33Use intense anime action cinematography: tilted low-angle face-off, extreme eye close-ups, ground-level sprint tracking, upward falling shot, impact-frame cut, rapid hand-to-hand exchange, debris crash, low center tracking shot, and final wide hero frame. Camera can be aggressive, but the choreography must stay readable.
34MOTION:
35Kairo’s motion is explosive, grounded, and feral: crouch, sprint, punch, kick, skid, ground slam, leap.
36Renji’s motion is precise, floating, and elegant: hover, descend, parry, gravity step, slash, final dive.
37Energy trails, scarf, coat, hair, dust, rocks, sparks, lightning, and smoke should have strong secondary motion.
38LIGHTING:
39Dusk orange backlight, red-black flame glow from Kairo, blue-white lightning glow from Renji, smoke haze, flying sparks, high-contrast anime battle lighting. Keep faces and silhouettes clear.
40ENDING:
41The final frame must clearly show Kairo and Renji on opposite sides of the crater, both still standing after the clash, with red and blue energy fading in the smoke. The ending should feel like a viral high-quality shonen fan animation moment.
