Create a 15-second trailer for a Japanese youth baseball animated film. The story unfolds in the 1990s, set at an ordinary high school in a small coastal town in Japan. The school’s baseball team has been knocked out in the first round of the summer tournament for three consecutive years, and third-year ace pitcher Akiyama Shun is facing his final high school summer season. If they fail again, his and his teammates’ high school baseball careers will come to an end.
The visual style should capture the authentic 1990s Japanese cel‑animation aesthetic: hand-drawn lines with crisp dark outlines and flat shading; traditional two‑tone cel lighting; watercolor backgrounds with slightly faded blue‑green and golden hues; simulated 35mm film grain, subtle camera shake, occasional tiny scratches, and flickering exposure. Animations should feature the classic frame‑by‑frame tension of old-school anime, with exaggerated speed lines, splashes of sweat, and brief freezes on key moments. Avoid any sense of 3D modeling, modern digital illustration, or neon‑style effects.
The atmosphere must blend bright, scorching Japanese summer sports vibes with the tense, thrilling, and passionate energy of knockout tournament matches. Intense summer sunlight bathes white baseball uniforms, while the sky is a deep azure, dotted with slowly drifting cumulus clouds. Around the field, green protective nets, utility poles, low school buildings, and leaves swaying gently in the breeze create a vivid backdrop. Heat waves distort the air, characters are drenched in sweat, and cicada chirps fill the first half of the scene.
Main Characters
Protagonist Akiyama Shun, 17, a third-year Japanese high school boy and the team’s star pitcher. Standing about 178 cm tall, he has a lean yet sturdy build, with well-defined muscle lines from years of training. His skin is lightly tanned by the sun, his short black hair slightly disheveled, strands of forehead hair dampened by sweat. He has deep brown eyes, usually calm and composed, but sharp and resolute during games.
He wears a white short-sleeved baseball uniform with navy blue piping along the collar and cuffs, bearing the fictional school name “Aonagi” on the chest and jersey number “11.” His white pants have red clay stains on the knees, paired with a dark blue cap, black pitching glove, and black cleats.
Catcher Mori Daichi, 17, Akiyama Shun’s close friend. Stocky and strong, with a buzz cut, thick eyebrows, and sun-kissed skin, he has a straightforward, no-nonsense personality. He dons the same white uniform, wearing jersey number “2,” along with dark blue catcher’s gear and mask. At crucial moments, he crouches behind home plate, clenching his fists to encourage the protagonist.
The opposing batter is tall and imposing, clad in gray away‑team attire, gripping a metal bat with both hands, his expression tense yet focused.
Storyboard and Sound Design
0–2.5 seconds: A hot, quiet ballpark
An overhead shot reveals a summer high school baseball field. Golden sunlight slants across the diamond, turning the red infield soil pale and dry, while green protective nets shimmer faintly in the heat. Massive white cumulus clouds loom against the azure sky, leaves rustling gently in the breeze.
The camera quickly zooms in toward the pitcher’s mound. Akiyama Shun stands alone under the sun, practicing his pitches. He slowly lifts his left leg, rotates his waist, and swings his right arm with force. Beads of sweat fly off his chin and hair tips as the white baseball hurtles toward the camera.
Close-up of the catcher’s mitt: the ball smacks into the glove, leaving a temporary dent, dust and sweat scattering in the sunlight.
Sound:
At the start, only loud, continuous cicada chirps and distant rustling leaves can be heard.
As the pitch is thrown, add the sound of fabric rubbing against the uniform and sharp wind slicing through the air.
The catch must sound heavy and crisp: “Bashin!”
A deep, resonant male narrator intones:
“Three years running—first-round defeat.”
English translation: “Three years in a row, eliminated in the opening round.”
Music: One or two subtly melancholic piano notes, followed by very light, low-frequency drum beats.
2.5–5 seconds: Memories of failure and the final warning
Set to the drumbeat, three brief flashbacks unfold:
An old mechanical scoreboard displays “Aonagi 0 — 1,” with the last red “out” light glowing brightly.
Akiyama kneels on the red clay of the mound, his cap shading his eyes, fists tightly clutching handfuls of dirt.
Teammates sit in the dimly lit dugout, their uniforms soaked with sweat, silence hanging heavy in the air. Bright sunlight streams in through the dugout entrance, casting them in shadow.
Coach stands at the dugout doorway. About 50 years old, with short gray hair, a stern face, and sun-tanned skin, he wears a white training jacket. Without shouting, he speaks in a low, firm voice:
“If we lose, your summer ends here.”
English translation: “If we lose, your summer ends here.”
As the final word “ends” fades, the screen briefly goes black for half a second, leaving only cicada chirps.
5–8 seconds: The team rallies
Suddenly, snare drums, bass, and electric guitars with a distinctly ’90s youthful anime vibe kick in, accelerating the tempo.
Quick, successive close-ups:
Akiyama tightens his shoelaces, veins bulging on his hand.
Mori snaps his catcher’s mask onto his face, staring straight ahead through the protective gear.
A teammate slaps his cheeks to wake himself up.
A practice swing sends white dust flying from the glove.
The entire team gathers in a circle in the dugout, stacking their right hands atop one another.
Sunlight filters through the fence, creating dancing patches of light and shadow on everyone’s faces.
Akiyama lowers his cap brim, lifts his head, his gaze shifting from exhaustion to determination. In a slightly hoarse, restrained yet powerful teenage voice, he declares:
“We’re not done yet. One more win—we’ll definitely take it.”
English translation: “We’re not done yet. One more win—we’ll definitely take it.”
Teammates shout in unison:
“Ooh!”
English translation: “Yeah!”
8–12.5 seconds: The decisive game
As the match reaches its climax, rapid cross‑cuts heighten the tension:
The packed stands erupt as students wave towels, summer sunlight painting every face.
The scoreboard reads “1–1” in the bottom of the ninth, with two outs and a full count.
Catcher Mori crouches behind home plate, pounding his glove with his fist and shouting:
“Akiyama! Give it everything you’ve got!”
English translation: “Akiyama! Throw everything you’ve got!”
Akiyama stands on the mound, gasping heavily. Sweat pours down his cheeks and neck, his right fingertips stained with red clay.
He closes his eyes for a moment, memories flashing back of training under the setting sun, running together, laughing side by side.
Then he opens his eyes sharply, his pupils reflecting the catcher’s mitt.
The camera circles around the pitcher’s swift motion. Akiyama lifts his left leg high, arching his body like a drawn bow before lunging forward. His right arm swings with all his might, cleats kicking up clouds of red clay, sweat forming bright arcs in the intense backlight.
The baseball spins rapidly toward home plate. The background transforms into hand‑drawn blue‑white speed lines, the camera tracking the ball’s relentless advance. The opposing batter grits his teeth, swinging with everything he’s got.
Sound:
The crowd’s cheers gradually fade into muffled ambient noise.
Akiyama lets out a short, urgent shout as he throws: “Goe!” (Go!)
Two strong heartbeats echo repeatedly.
The crack of the ball cutting through the air grows louder and louder.
Just as the ball is about to meet the bat, the music abruptly stops.
In the instant before impact, the screen flashes brilliantly white and freezes—but do not reveal the outcome.
12.5–15 seconds: Title and lingering summer vibes
After the freeze, a brief blackout, leaving only a crisp, suspenseful metallic clang:
“Kakīn!”
The scene then shifts to the sunset‑lit ballpark. Akiyama and his teammates walk shoulder to shoulder, silhouetted against the orange‑gold glow of the setting sun. Long shadows stretch beneath their feet, white uniforms fluttering gently in the evening breeze, while massive summer clouds turn a fiery orange‑red.
The male narrator’s tone grows impassioned yet warm:
“Our summer isn’t over yet.”
English translation: “Our summer isn’t over yet.”
In the center of the screen, the hand‑drawn title appears:
“The Last Summer, The Last Game”
Below, in smaller letters:
“This summer, let the game begin.”
English translation: “This summer, let the game begin.”
The music peaks with soaring electric guitar and brass, then concludes cleanly at the 15‑second mark.
Voice Acting Requirements
All characters and narrators must speak natural Japanese—no Chinese dubbing allowed.
Akiyama Shun: A 17‑year‑old Japanese high school boy with a clear, slightly husky voice—restrained in the first half, bursting with youthful intensity during the game.
Mori Daichi: A loud, direct voice, radiating the passion and trust of an athlete.
Coach: A deep, measured male voice in his fifties, speaking slowly and solemnly, without anger or rage.
Narrator: In the classic ’90s Japanese sports anime style—deep, weighty, and deeply moving, building to an uplifting crescendo at the end.
Dialogue must closely match lip movements, avoiding mechanical delivery.
Background Music Guidelines
Original score inspired by ’90s Japanese youth sports anime—no imitation of specific works. Begin with cicada chirps, gentle piano, and steady heartbeat drumming; gradually introduce fast snare rolls, melodic electric bass, bright electric guitar, and warm brass sections. During the climactic battle, accelerate the tempo dramatically, capturing the tension of a dramatic comeback and youthful fervor. Stop the music abruptly at the moment of impact; conclude with soaring electric guitar, brass, and drums when the title appears. Aim for a warm, slightly compressed texture reminiscent of analog tape recordings.
Negative Guidelines
Avoid modern digital anime styles, 3D characters, CG stadiums, plastic skin, overly smooth textures, neon cyberpunk aesthetics, fantastical abilities, glowing baseballs, superhero tropes, exaggerated muscles, professional adult players, Western characters, modern smartphones, contemporary stadiums, garbled text, incorrect Japanese, deformed fingers, extra limbs, inconsistent character costumes or numbers, sudden changes in appearance, unnatural pitching mechanics, slow pacing, comical expressions, chibi designs, excessive sadness, graphic injuries, or premature reveal of the game’s outcome.
