Mato Seihei no Slave/Chained soldier is a serialized manga and anime series created by Takahiro. When entries to a different dimension, known as "Mato," appear throughout Japan, a new resource, known as "Peaches," is discovered, granting unique abilities only to women. However, dangerous monsters called "Yomotsu Shuuki" also roam Mato and have been responsible for several disasters since then. To combat them, the government formed the Anti-demon Corps, an elite group of women who received power from the Peaches.
