A young woman sets out to bring the art of tea to the stars!

In the not-too distant future, mankind has colonized space and achieved utopia as a civilization.

Volunteers work 25-year shifts at the edge of the explored galaxy to gather resources for the peaceful world of Earth. These workers live in makeshift colonies on the asteroids and moons where they labor. In one such colony, a melancholy woman from Neo-Kyoto opens a traditional Japanese tea room. This is her slice-of-life story as she tries to bring a little bit of Chanoyu to the distant stars.
