A wonderful and mysterious birthday adventure, one that you will never forget. Beyond the basement door in Aunt Chi’s antique shop lies a world beyond your wildest imagination…

Akane Uesugi is a shy 6th grader who has trouble telling other people how she feels.

The day before her birthday, her mother, Midori, sends her on an errand: to go get her birthday present from her free-spirited Aunt Chi’s antique shop. But a strange man named Hippocrates the Alchemist, who calls her the “Green Goddess,” together with Pipo the fairy, takes her on a journey to “The World Beyond” from a door in the basement.
There, the water has dried up and the trees are losing their color. Can she save it with the help of her free-spirited Aunt Chi, the stern Hippocrates, and his apprentice Pipo?
