In the smash-hit miniseries TMNT: The Last Ronin, readers witnessed the final gut-wrenching days of the Heroes in a Half Shell. For Michelangelo in particular, the march to his heartbreaking last battle was long and dangerous, taking him from New York City, to Japan, across Asia and Europe, and then back home again to administer final justice against those guilty of killing his family. But what happened during those fateful years when he had only the need for vengeance and Master Splinter's journal to guide him? What battles did he fight? What hard lessons did he learn? The time has come to find out as original miniseries writers Kevin Eastman and Tom Waltz join artist Ben Bishop to reveal what adventures the Last Ronin experienced during his vengeful journey. While in the present, a new master, Casey Marie Jones, prepares her young terrapin students to be the next generation of Teenage Mutant Ninja Turtles!
