Chained Soldier is based on the popular manga series written by Takahiro, known for Akame Ga Kill!, and illustrated by Yohei Takemura. The manga has been serialized on Shueisha’s Shonen Jump+ online platform since January 2019, with Yen Press publishing the series in English.
The story is set in a world where mysterious gates to a dangerous dimension called “Mato” have appeared, unleashing monsters known as Shūki. Unique abilities are granted to those who partake in “peaches” growing there, but only if they are girls. The plot follows Yuuki Wakura, a high school boy who finds himself caught in a Mato gate and is saved by Kyouka Uzen, the beautiful commander of the 7th squad of the Demon Defense Force, who subsequently orders him to become her “slave” to harness his unique power.
The first season of the Chained Soldier anime premiered in Japan in January 2024 and was streamed on HIDIVE. The second season is set to stream worldwide from January 2026.
