The Duel Masters LOST anime's fourth part, Duel Masters LOST: Danzai no Shonen, streams from October 9, 2026, with a fifth manga part announced and the fourth manga part concluded.
The Duel Masters LOST franchise is in the middle of a rapid expansion across anime and manga. The fourth anime part, Duel Masters LOST: Danzai no Shonen, debuts October 9, 2026, with a four-episode run on DueTube and other streaming services. New episodes arrive every other Friday at 9:00 p.m. JST. The key visual places protagonist Zanba Win reaching toward the mysterious boy Kami Misaki Lost, who holds the Crystal Card. The story follows Win after he leaves a lighthouse carrying the sensation of having taken a life through further assimilation with the Jashin Emperor, leading into a battle over the Crystal Card in Shinjuku, where suspicious deaths continue.
The production team returns largely intact. Riki Fukushima directs at J.C. Staff and SMDE, with Yuji Matsukura supervising animation production. Yoichi Kato writes the scripts, Chikara Hashizume designs the characters, and Go Sakabe composes the music. Nina Tamaki voices Lost, having previously voiced a mysterious boy in the earlier anime. The announcement also included Return of Duel Masters Lost Mini shorts and recap videos, framing the fourth chapter as an event with its own marketing cadence.
The manga side mirrors the anime's progress. The fourth manga part, Duel Masters LOST ~Danzai no Shōnen~, ended with its 11th chapter on July 2. The same chapter revealed a fifth part, Duel Masters LOST ~Shitsuraku no Duel~, is coming, continuing the pattern where each part receives a separate anime adaptation. No release date for the fifth part's anime has been announced. The serialization pace across both GT and LOST keeps the trading card game's storylines active.
