In this bold, R-rated reimagining of the beloved franchise, Teenage Mutant Ninja Turtles: The Last Ronin dives into a dystopian future where the once-great heroes in a half shell are no more — all but one.

Set decades after the fall of the Turtles, New York City is a totalitarian fortress under the control of Oroku Hiroto, the heir to the Shredder’s brutal legacy. Amid the shadows, a lone figure strikes back from the ruins: the Last Ronin — a grizzled, older mutant turtle shrouded in black, carrying the weapons of his fallen brothers.

With only the voice of Master Splinter’s journal to guide him, and haunted by the memories of Leonardo, Raphael, Donatello, and Michelangelo, the Last Ronin embarks on a brutal mission of justice, redemption, and reckoning. As the truth behind the clan’s destruction is slowly revealed, allies both new and familiar rise — including April O’Neil and her daughter, Casey Marie.
