Hakkenden: Touhou Hakken Ibun

Five years ago, almost every villager of Ootsuka died due to a tragic
plague. But mysteriously enough, three survivors: a girl and two boys,
emerged. Now living in a church, the three live in isolation, hidden
from those who may seek to find them. Shino, one of the survivors, has
control over the power of Murasame, the blade of life. But when the
imperial church seeks to take the Murasame for themselves, their
peaceful life becomes a thing of the past...
