Free · the ANIME prompts

Your favourite anime,
as tiny 3D worlds.
But you only need one prompt.

Attack on Titan, One Piece, One Punch Man, Naruto, Demon Slayer, Dragon Ball and Jujutsu Kaisen as living voxel dioramas, written entirely as code. No Blender, no 3D models, no animators. Every character moves, and the big moments play out on a loop. Here are the exact prompts.

STEP 1Pick a world below and hit Copy full prompt.
STEP 2Paste it into Claude Code (or any coding agent) in an empty folder.
STEP 3Let it screenshot its own page and fix what it sees. Then swap in your own world.

The base spec shared by every world

Build a living anime diorama as ONE self-contained HTML file using three.js (r170 via an importmap from jsdelivr). Everything in the world must MOVE, and the iconic moments of the anime must play out on a loop.

Small-block characters (this is what makes it look good):
- Build every character from a dense voxel grid (~30 voxels tall, voxel size ~0.03), NOT from a handful of boxes. Write a Vox grid class (set/box/ellipsoid/cylinder/paint) and turn each grid into ONE merged, face-culled, vertex-coloured BufferGeometry with a tiny per-voxel colour jitter.
- A character = separate parts (head, torso, two arms, two legs, optional cape and held props), each its own merged mesh on a pivot, so they can walk, run (arms-back ninja run), punch, swing and fall.
- Anime faces: big 2x3-voxel eyes with a dark lash row, a coloured iris and a white highlight voxel; small mouth. Real hairstyles made of voxels around the head: spiky (cones of voxels leaning back), bob, long, messy, bald. Hats, headbands with metal plates, scarves, capes with emblems, outfit details painted voxel by voxel (straps, belts, open jackets, logos).
- Giants (titans, monsters, tailed beasts, spectral warriors) use the same builder with a bigger voxel size.

The world:
- A floating island: a grass slab on a dirt band with a jagged voxel underside (InstancedMesh columns, deeper toward the middle), small mini-islands bobbing around it, drifting clouds and birds.
- Flat-shaded props built as merged voxel meshes or InstancedMesh (keep draw calls low). An InstancedMesh particle system for steam, smoke, dust, splashes and debris.
- Each signature moment is a state machine on a timeline (the first big moment within ~5 s), with its own camera preset that frames it.
- Day/night: a time slider sets the sun, sky gradient and hemisphere light; at night windows, lanterns, torches and energy attacks glow (emissive + UnrealBloom) and stars fade in.
- UI: a small frosted panel with a serif title, time and speed sliders, Day cycle and Orbit toggles, camera preset buttons, a stats line. ?clean hides it, H toggles it. OrbitControls with a slow auto-rotate; the default view is the whole island, zoomed out.

Quality bar: dense, tidy, toy-like, every character readable as who they are. No console errors.

Titan Wall

Scouts swing on ODM gear and slash titans, cannons fire from the wall, and the Colossal Titan grabs it in a lightning flash.

The world: a walled town on a round floating island. A circular stone wall (instanced stone blocks, crenellations, a gate that lifts) around a dense medieval town (timber-frame houses with red/blue/purple roofs, a church with a bell tower), fields and a forest of giant trees outside.
- Titans (big voxel humanoids with grins full of teeth, different proportions: big-headed, thin, bulky) walk around outside the wall, heads turning, sometimes reaching up at it.
- Survey Corps scouts (Eren, Mikasa with her red scarf, Levi, and others: cropped tan jackets, harness straps, white trousers, tall boots, green cloaks with the two-wing emblem, gas canisters, a blade in each hand) perch on the wall and the giant trees, fire grapple lines and swing on arcs with gas trails to a titan's nape, spin-slash it, and the titan falls forward and dissolves in steam, then respawns at the edge.
- Every ~26 s the Colossal Titan (skinless, red muscle stripes, a wall of teeth) appears in a lightning flash, grips the top of the wall and stares in while the townsfolk panic and run.
- Cannons on the wall turn to aim and fire at the nearest titan (smoke, shells on arcs, hits). Garrison soldiers patrol the top.
- Night: torches ring the wall, windows glow.
Default time 15:00.

Pirate Seas

Luffy goes Gear 2 → 3 → 4 → 5, punches a giant dragon into the sea, and the whole Straw Hat crew is on deck.

Read the world prompt
The world: a floating island whose middle is open sea (an animated wave shader with foam; boats bob and roll on the same waves sampled on the CPU). A port town island, a Marine fortress with a beacon tower, a palm beach islet.
- The Straw Hat ship (Going Merry: sheep figurehead, striped mast, straw-hat Jolly Roger) sails a loop with the full crew doing things: Luffy, Zoro (three swords), Sanji, Nami, Usopp, Chopper, Robin, Franky, Brook, Jinbe.
- A Marine warship chases it and fires cannons (smoke, splash columns).
- Luffy's GEAR cycle is the storyline, each stage on a close camera on the open foredeck:
  Gear 2 (pink skin, thick steam, afterimage punches) → Gear 3 (bites his thumb, one arm inflates to a fist bigger than the hull, Gigant Pistol on a Marine admiral, then he shrinks chibi) → Gear 4 Boundman (twice-as-wide torso, black and red banded arms and legs, a cloud scarf, bouncing high, Kong Gun) → Gear 5 (white hair and clothes, a cloud ring, bright white glow and a drumbeat pulse, cartoon rubber bouncing, grabs lightning).
- A Kaido-style giant blue Eastern dragon (24 undulating voxel segments, horns, mane) arcs over the sea and breathes a fire beam; Gear 5 Luffy punches it down into the sea with huge splashes.
- A Sea King rises out of the water, roars and sinks. Gulls and a News Coo.
- Night: ship lanterns, port windows and the fortress beacon glow.

One Punch City

Saitama one-punches monsters into the sky, the boss gets a Serious Punch, and Genos fights with fire blasts.

Read the world prompt
The world: a city on a round floating island: voxel skyscrapers and apartment blocks, ring roads with traffic, a supermarket with a SALE banner, the Hero Association tower, a park, and a wrecked district with craters and rubble.
- Giant monsters (an ogre, a giant crab, a deep-sea king, a meteor golem) smash through buildings (debris, dust, then the building rebuilds later) while civilians flee.
- Every encounter happens on a cleared central plaza: Saitama (bald, deadpan dot eyes, yellow suit, white cape, red gloves and boots) walks in carrying a grocery bag, thinks "Sale ends at 8...", puts the bag down and throws ONE punch: a short slow-mo, a white flash ring, speed lines, the monster bursts into voxel chunks flying up into the sky, the clouds part. He picks up his bag and walks on.
- Every third cycle a Boros-like one-eyed armoured alien boss says "Finally, a challenge" and gets a SERIOUS PUNCH: a far bigger blast that punches a hole through the clouds.
- Genos fights another monster with orange incendiary blasts, gets knocked back sparking, then finishes it.
- Other heroes, a hero blimp, a helicopter, police and fire trucks with flashing lights.
- Night: thousands of lit windows, neon, sirens, glowing monster eyes.

Ninja Village

Pain flattens the village, Naruto becomes Kurama, and Madara’s Susanoo clashes with it over the Hokage faces.

Read the world prompt
The world: the Hidden Leaf village on a big floating island: a cliff with four carved Hokage faces, the round red Hokage tower, warm orange/red/cream houses, the big gate with green doors and the leaf emblem, Ichiraku ramen with its curtain, a training field with three posts, a river with a red bridge and a waterfall off the edge, forests.
- Ninjas dash across rooftops in the arms-back run and leap roof to roof; others hop between treetops. Kakashi reads on a roof.
- A 50 s story loop:
  Pain (orange spiky hair, piercings, Akatsuki cloak) floats above a district and casts Almighty Push: an expanding sphere that blasts the houses into voxel debris and leaves a crater →
  Sage Mode Naruto arrives and fights him with Rasengans →
  the orange Nine-Tails chakra cloak forms, and Naruto becomes the giant Kurama (nine swaying tails, red slit eyes, a Tailed Beast Bomb) →
  Madara (long spiky black hair, red armour) summons a Susanoo (a giant translucent violet spectral samurai with a glowing sword) and they clash with flashes and shockwaves →
  everything fades, the district rebuilds, and the shadow-clone army and Rasengan vs Chidori play on the training field.
- Night: lanterns, windows, the ramen stand, fireflies, and the giants glowing over the village.
