Chained Soldier

The battle fantasy is set in a world where a demonic gate has unleashed monsters known as Shūki. A special peach tree is able to give special powers, but only to women. The story begins when a down-on-his-luck boy named Yūki Wakura meets Uzen Kyōka, a girl who has gained the power of the peach, and is the captain of the 7th Anti-Demon Squad.
