Worldview

Death Note is a psychological thriller set in contemporary Japan, where the boundary between human justice and divine murder collapses. When Light Yagami discovers a notebook that kills anyone whose name is written in it, he adopts the identity of Kira and begins purging criminals to create a new world. Legendary detective L, later succeeded by Near and Mello, leads a secret investigation to unmask him, while the shinigami Ryuk watches from the shadows. Every move is a duel of intellect, morality, and absolute power.

In a world that looks almost ordinary, a black notebook falls from the realm of gods of death. Whoever writes a name inside it can kill — and a brilliant student decides that the power belongs to him alone. What follows is not a crime wave but a philosophical war: Light believes he can become the god of a new world; L and his successors fight to prove that no one has the right to judge humanity through murder.

Studio Interior

This is the actual studio workspace for the Death Note world — the Board view with every atom card, the Gallery of generated art and works, and a character detail overlay. The world is not the end point, but the starting point of all creation.

World, Not Work

In Neta Studio, a world is the beginning of everything. A world contains characters, locations, events, items, and rules — 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, and video assets — each inheriting the same worldview, the same settings, the same duel of justice and absolute power.

World → Game

Select a storyline from world cards, AI auto-writes game logic, generates art, builds a playable visual novel like Death Note: First Judgment.

World → Video

Generate dynamic videos from world characters and scenes — first-person POV shorts, 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.
