Duel Masters LOST Danzai no Shōnen (The Sentencing Boy) is set to continue the franchise's experimental streaming run, with a premiere date confirmed for October 9. The new project will consist of four episodes, following the established pattern of previous entries in the Duel Masters LOST series.
Returning to the helm is director Riki Fukushima, who will lead production at J.C. Staff and SMDE. The creative team remains largely unchanged from previous installments, with Yūji Matsukura overseeing animation production, Yōichi Katō managing series composition, and Go Sakabe returning to score the music. Character designs are once again handled by Chikara Hashizume, while Nina Tamaki reprises her role as the lead, Lost Kōzaki.
The series will maintain its digital-first distribution model, with new episodes releasing every other week on the official Duel Masters YouTube channel. This installment adapts the fourth part of the Duel Masters LOST manga saga, which concluded its run in July 2026. Following the success of the Tsuioku no Suishō, Gekka no Shinigami, and Bōkyaku no Taiyō adaptations, this latest chapter serves as a direct continuation of the franchise's ongoing expansion into episodic web animation.
