Almost all the inhabitants of Ootsuka lost their lives to a sorrowful plague half a decade ago, and only a trio survived - a girl and two boys. They have remained hidden within the premises of a church, living in seclusion. One of the survivors, Shino, has the ability to control the life-giving blade, Murasame. Nevertheless, their tranquil life is rudely interrupted when the imperial church aims to take hold of Murasame for their own purpose.
