Mayonaka Garan is set in the rural Japanese village of Daiusu, where a community of Christians has lived in seclusion for many generations. Hamomoru Tachibana is invited to this village as a guest. The village has just finished building its long-dreamed-of cathedral, and the mood is celebratory. The villagers wish to use this moment to enter the modern world of the 1920s. As part of this, Hamomoru is tasked with archiving the history and legends of Daiusu.

Located in a secluded part of Japan, the village, due to a long history of oppression, has seen its faith take a peculiar turn.
The Faith of the Saint.
The villagers have come to project their hopes for salvation onto a "Saint" who came from the outside world.

This tradition of treasuring friendly visitors seems perfectly suited to modernizing the village.
And yet.
Just as the village begins to come together, a restless shroud still hangs over it. Individual motives begin to clash, and miracles occur as if to make a mockery of everything...

What will become of Daiusu's attempt to enter the wider world?
