Ayuma is a world full of fairies and magic. Here, Crystal, Knight, and Forest Fairies live harmoniously together in a fairy community, if it weren't for the Bat Fairies. They are always trying to steal the energy crystals from the magical source and use them for their own purposes. In the enchanting fairy world of Ayuma, it rains continuously. The fairies watch the developments with concern, and soon disaster strikes. The river that flows through the entire land and distributes the magic and life force of the crystals has overflowed its banks. Now everyone must work together to save the Tree of Wisdom from the floodwaters. But how did this happen, and what do the Bat Fairies have to do with it?.
