In 2026, it seems like TMNT: The Last Ronin mania is burning brighter than ever. The original series is set to receive a novelization soon, and we just learned that PlatinumGames has now taken charge of The Last Ronin video game. Meanwhile, on the comic book side of things, IDW is gearing up for the release of the latest spinoff, TMNT: The Last Ronin: Training Day.
With today marking the final order cutoff for TMNT: The Last Ronin: Training Day #1, IGN can exclusively debut a new preview of the book. Check out the slideshow gallery below to see two new pages of interior art, along with the previously revealed covers:
Training Day reunites the original Last Ronin creative team, including writers Kevin Eastman and Tom Waltz, artists the Escorza brothers and Ben Bishop, and colorist Luis Antonio Delgado. Here's the official logline for the issue:
The training mission you didn’t see!
Michelangelo only has a short time to get young Casey Marie Jones prepared for battle against Oroku Hiroto. How can the Last Ronin distill a lifetime’s worth of training and knowledge into one day? Read the epic tale of action and legacy too big to fit into the pages of the original book, written and drawn by the original Last Ronin team!
This makes Training Day the fourth book in the Last Ronin saga, following the original 2020 miniseries, 2022's TMNT: The Last Ronin – The Lost Years, and 2023's TMNT: The Last Ronin II – Re-Evolution. Eastman and Waltz confirmed to IGN that another direct sequel is in the works, though we don't know the release date yet.
TMNT: The Last Ronin – Training Day #1 will be released on July 15, 2026. You can preorder a copy at your local comic shop.
