Chained Soldier, known in Japan as Mato Seihei no Slave (Japanese: 魔都精兵のスレイブ, Hepburn: Mato Seihei no Sureibu; lit. 'Slave of the Magic Capital's Elite Troops'), is a Japanese web manga series written by Takahiro and illustrated by Yohei Takemura. It has been serialized on Shueisha's Shōnen Jump+ online platform since January 2019.

The series is set in a near-future Japan where portals to a dangerous dimension, called Mato, have appeared across the country. In response, the government establishes the Mato Defense Force (MDF), a special military unit composed of superpowered women, to protect humankind and fight the dimension's inhabitants. The story follows Yuuki Wakura, a young man who accidentally wanders into Mato and is rescued by Kyouka Uzen, a top-ranking MDF officer.

An anime television series adaptation, animated by Seven Arcs, aired from January to March 2024. A second season, animated by Passione and Hayabusa Film, premiered in January 2026.

By June 2025, the manga had over 5.5 million copies in circulation.
