Worldview

The sea is the only law. In a world of islands, currents, and dreams, pirates, Marines, revolutionaries, and the World Government all fight over the same blue frontier. Devil Fruits grant supernatural power — and exile their users from the sea. The Grand Line is a gauntlet of impossible weather, ancient ruins, lost history, and the legendary treasure that started it all: ONE PIECE.

A boy in a straw hat laughs from the bow of his ship. Behind him: crewmates, a flag, and an endless blue. Monkey D. Luffy and the Straw Hat Pirates sail island to island, tumbling into the oppression, war, and dreams of every shore — while the World Government buries the truth of the Void Century beneath the waves.

Visual style: cel shading, sharp shadows, flat color — a bright, saturated pirate adventure with bold anime linework. Kimi K3 GPT Image 2

Studio Interior

World, Not Work

In Neta Studio, a world is the beginning of everything. A world contains characters, locations, events, factions, and ability systems — all generated by AI from a single sentence, all referenceable, rewritable, and expandable.

A world is not a game, a video or an image. A world is the source of all of these: from the same Grand Line, you can generate playable adventures, character portraits, newspaper spreads, video vlogs — each inheriting the same worldview, the same settings, the same conflict.

World → Game

Select a storyline from world cards, AI auto-writes game logic, generates art, builds a playable adventure on the Grand Line.

World → Video

Generate dynamic videos from world characters and scenes — crew vlogs, deck moments, island reveals.

World → Assets

Each character auto-generates a cover, each island auto-generates a background. The world itself is an asset library.
