Mana's friend Miyabi has quarreled with her mother over something trivial. When she wishes she could go back to when she was little, she suddenly finds herself lost in a forest. There live mysterious children, forest spirits, the Kinoko. They invite Miyabi to play, and Miyabi innocently joins them. In the Kinoko forest, there are no adults, no school. It's a world with nothing to tie her down. Miyabi begins to wish she never had to leave. But, slowly, Miyabi's mind and body mature while the Kinoko around her stay the same, leaving her baffled. That's when Kitaro appears after receiving a request from Mana. Will Miyabi return to her old world, or will she stay in the forest?
