At the beginning, the world had only one season, Winter. Winter, unable to bear its loneliness, gave up part of its life to create Spring. Eventually, the earth's wish brought Summer and Autumn into being, completing the four seasons. The changing of seasons was to be carried out by human children, and those who fulfilled this role were called "avatars of the four seasons."

Hanaha Hinagiku, the incarnation of Spring, together with her escort Sakura Himetaka, begins to travel around the land of "Yamato" in order to bring about the spring season for the first time in ten years...? The sad but beautiful "Tour of Spring" chapter of the story about living deities and their guardians, who are responsible for bringing the seasons into the world, opens here.
