The official website for the Duel Masters LOST anime initiative has confirmed that its fourth installment, Duel Masters LOST ~Danzai no Shōnen~ (The Sentencing Boy), will begin streaming on October 9. The upcoming release follows the four-episode structure established by earlier entries, with new installments launching every other week on Fridays at 9:00 p.m. JST via the official Duel Masters YouTube channel and related digital platforms.
Established Production Team Returns
Animation production remains in the hands of joint studios J.C. Staff and SMDE. Director Riki Fukushima returns to lead the project under the animation production supervision of industry veteran Yūji Matsukura. Script composition is once again handled by Yōichi Katō, with Chikara Hashizume returning for character designs and Go Sakabe providing the soundtrack. Voice actor Nina Tamaki is set to star as Lost Kōzaki, following her earlier performance as the mysterious youth in preceding chapters.
This fourth anime arc directly adapts the manga created by Yō Kanebayashi and Shigenobu Matsumoto, which debuted in March 2026 following previous installments Tsuioku no Suishō, Gekka no Shinigami, and Bōkyaku no Taiyō. The multimedia project continues to expand the trading card game's lore into darker narrative territory through tightly structured web animation releases.
