First Rebuild World Key Visual

Akira and Alpha Lead the New Visual

The first key visual carries the line “Put everything on the line to survive.” Akira stands at the front with Alpha behind him, surrounded by a ruined landscape that immediately establishes the story's post-civilization setting.

It reflects the central premise: Akira risks his life as a Hunter to escape poverty, while his encounter with Alpha changes the path ahead of him.

Raging Bull Handles Animation Production

The new announcement also confirms the core production team.

Tsukasa Sakurai serves as chief director, with Shingo Uchida directing. Naoki Tozuka handles series composition, Hiromi Katō and others are responsible for character design, and Raging Bull produces the animation.

Akira and Alpha's Contract Starts the Story

Rebuild World takes place among the remains of the Old World, a civilization whose technology once far exceeded that of the current era.

Akira is an inexperienced Hunter from the slums who enters dangerous ruins searching for a way to change his life. There he encounters Alpha, a mysterious woman only he can see. She offers her assistance in exchange for his help conquering a specific ruin in secret.

The Three Lead Cast Members Return

The previously announced principal cast remains attached to the anime.

Daiki Yamashita voices Akira, Yurika Kubo plays Alpha, and Honoka Inoue voices Sheryl. No new cast members were announced alongside the October 2026 visual.

The Premiere Window Is Still Unknown

While the latest update finally identifies the production studio and creative leads, it does not establish when the series will air.

A premiere year, broadcast season, episode count, network, streaming service, main trailer and theme songs all remain unannounced.

Why This Matters

1) The anime project is visibly moving again

Its studio and main staff are finally confirmed more than three years after the original anime announcement.

Game Ad

Major Mutt

2) The Old World is central to the adaptation's visual identity

Futuristic ruins, technological relics, weapons and monsters are fundamental to the source material.

3) Akira and Alpha remain the core of the adaptation

The first key visual once again builds the anime around the contract between its two central characters.
