The latest chapter of The Marshal King has confirmed that the series will reach its conclusion in the next installment, set to arrive on October 16. The announcement comes shortly after the manga resumed serialization on September 4 following a hiatus that began late last year.

Launched by artist Boichi in February 2025, the series brought a distinct, high-energy take on the American Wild West to the Shonen Jump+ platform. Known for his dynamic visual style in works like Dr. Stone and One Piece: Ace's Story, Boichi utilized this project to explore the gritty dynamics between outlaws and the lawmen tracking them. Shueisha has collected the series into three volumes as of November 2025.

For readers following the series internationally, Viz Media and the MANGA Plus service have been handling the English-language distribution. While the conclusion of this project marks the end of Boichi's recent solo venture, the artist remains a significant figure in the industry, particularly for his long-standing collaboration on the Dr. Stone franchise, which recently concluded its multi-cour final season, Science Future.
