Studio Trigger Announces a Fourth Hiroyuki Imaishi and Kazuki Nakashima Project
The Gurren Lagann, Kill la Kill and Promare creative duo are reuniting for a new project, though no title or release date was given.

What Trigger announced
Studio Trigger has revealed that director Hiroyuki Imaishi and screenwriter Kazuki Nakashima are teaming up for a fourth project together. The studio shared the news from its official account with a teaser visual that stacks the logos of the pair's three previous collaborations above two words: "4th Project." No title, release window, format, or distribution details were given, and the studio simply asked fans to look forward to further updates.
The duo behind it
Imaishi and Nakashima are one of the most recognizable director and writer partnerships in modern anime, and their work together has become a defining thread of Trigger's identity. Their run began at Gainax with Gurren Lagann, the 27 episode science fiction adventure that first aired in 2007. They reunited for the 24 episode action series Kill la Kill in 2013, one of Trigger's early signature television works, and again for the 2019 theatrical science fiction film Promare. Across those three titles, catalogued here under genres spanning science fiction, action, adventure and comedy, the pair built a reputation for high energy spectacle and larger than life leads. The newly announced project places this fourth outing directly in that lineage.
According to Crunchyroll News, Hiromi Wakabayashi is also attached to the new project. Beyond the returning creative duo and that credit, no staff, studio production details, cast, or story information have been confirmed, so it is not yet clear how closely the new work will resemble any single one of the team's past hits.
Where it was revealed
The announcement was made during Studio Trigger's panel at Anime Expo 2026, as reported by Anime News Network and Crunchyroll News. The teaser art offers no plot hints beyond a shadowy mechanical silhouette in the background, and the studio has indicated it is too early in development to share anything further.
