Mato Seihei no Slave

Chained soldier

After his secondary school diploma, Yuuki Wakura realizes that it’s been five years since the disappearance of her sister during a “Mato” disaster. Throughout Japan, mysterious entrances have opened up to a dimension called “Mato” – a demonic metropolis filled with disastrous monsters known as  “Shuuki ” which threatens human safety. However, a new hope has occurred, because the discovery of a Mato fruit which exclusively grants supernatural capacities to women allowed them to fight against Shuuki. For this reason, a new matriarchal government has been trained, establishing a female organization called the anti-emotional body, which brought down men at the bottom of society.

When Yuuki suddenly finds himself in Mato, he is unable to escape by himself. But just as he plans a horrible end by the Shuuki, a girl in a militia outfit appears and protects him. As head of the seventh unit of the anti-Demon body, Kyouka Uzen is ambitious but devalued by his own peers because of the unusual judgment of his power. Now in a life or death situation, Kyouka takes the opportunity to discover the true potential of his superpower using Yuuki: to defeat the Shuuki, he must become his slave.
