AI Collaborative World Building
My Hero Academia: U.A. High School and the Age of Quirks
A complete world of Quirks generated by AI from the canon of My Hero Academia — 32 atoms, character sprites, scene art, and a playable U.S.J. Incident visual novel. The world is not the end point, but the starting point of all creation.
My Hero Academia is set in a near-future Japan reshaped by Quirks — superhuman abilities that appear in roughly eighty percent of the population. Professional heroes licensed by the state fight crime under public scrutiny, while a fractured underworld of villains seeks to tear that system down. At the center stands U.A. High School, training the next generation of heroes even as All Might’s era ends and a new age of chaos begins.
A once-quirkless boy inherits the power of the Symbol of Peace and steps into a war that will decide whether hero society survives. A society built on the spectacle of heroism is collapsing under inherited trauma, unequal power, and All For One’s long war — while the next generation must decide whether to save that system or remake it.

This world is public. You can Fork it — inherit all 32 atoms, all characters and scenes, rewrite what you want, and publish your own version.
Replace the U.S.J. with your own training ground. Add an OC to Class 1-A. Swap the cel-shaded 3D render for watercolor. The world is your asset library — rewriting is creation.
Collaborative workflow
Fork world → Edit atom cards → Generate new games/videos/assets → Publish → Others can Fork your version
Every Fork is a branch. Worlds grow through branching — there is no single canon, only infinite variants.

In Neta Studio, a world is the beginning of everything. A world contains characters, locations, events, factions, and quirks — 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 world, you can generate visual novel games, character sprites, scene backgrounds, video animations — 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 visual novel.
World → Video
Generate dynamic videos from world characters and scenes — title animations, character entrances, scene transitions.
World → Assets
Each character auto-generates a sprite, each location auto-generates a background. The world itself is an asset library.
