To the distant future. In the distance of the future.

In 2024, in a rural village called Kumano in a certain prefecture in Japan, two twelve-year-old childhood friends, Haruka and Mirai, were deeply wounded in both body and mind due to abuse from their families. Because of the abuse, both girls were constantly covered in injuries, and no one wanted to approach them. Living in the same circumstances, the two naturally spent long hours together, becoming each other's emotional anchor. In the midst of this, word comes that a volcano near the village is about to erupt. "If the world were to end tomorrow..." A quiet love story that two young girls secretly weave together.
