Mato Seihei no Slave Episode 6 English Subbed

Chained Soldier

After his graduation of the high school, Yuuki Wakura realizes that five years have passed since his sister's disappearance during a "Mato disaster ". In all Japan, mysterious entries have opened to a dimension called "mato ", a demonic metropolis full of disastrous monsters known as "shuuki " that threaten the safety of humans. However, a new hope arose, since the discovery of a mato fruit that gives supernatural skills exclusively to women allowed them to fight Shuuki. Because of this, a new matriarchal government was formed, establishing a female organization called Anti-Demon Corps, which caused men to fall to the bottom of society.

When Yuuki is suddenly in Mato, he can't escape on his own. But just when he anticipates a horrible end of Shuuki, a girl appears in a militia outfit and protects him. As head of the seventh unity of the anti-demon body, Kyouka Uzen is ambitious but devalued by his own companions because his power is considered unusual. Now in a life or death situation, Kyouka takes the opportunity to discover the true potential of his superpower using Yuuki: to defeat Shuuki, he has to become his slave.
