Based on the game by Studio Mirisu.

Taishou era. The interval between Meiji and Shouwa.
A season where yellow and red petals swoop down from the trees.
A young man comes down from the Imperial city, clinging to a large trunk, faintly smiling at the sight of the streets, a suitable young man indeed.
Just as told by his father, he reached to this town to help for an autumn festival. Walking down the streets brings a surge of nostalgia.
Encounter with a girl. Two girls.
As days drift by, the young man soon links with one of the girls. Not a love by chance. It was a fated love.
Was it the reason this young man was made to come to this town?
