Seijo no Maryoku wa Bannou desu

Definition

Since ancient times, the citizens of Slantania have lived within a shroud of miasma, a force that brings forth monsters creating havoc around the world. When the kingdom's Order of Knights becomes incapable of containing the monsters, the Grand Magus summons a holy maiden—the legendary "Saint"—to obliterate the horrid creatures and restore peace.
