On the Island of Spheres, three different births took place that day. Although they seemed like ordinary births to everyone, they were anything but normal. The leader of the Island of Spheres, Kula, had also become a father for the first time. One year later, Kula sets out to meet with other island leaders, accompanied by his partner Erguvani and their newborn child, Mai. However, as Kula departs, Hekton, who had heard of these spheres and their special powers, attacks the Island of Spheres and steals two of them. Mai is spared, as she is with her family. Hekton imprisons the stolen spheres on different islands to extract their powers. Upon hearing the news, Kula is forced to return to the island. When he arrives, Mai has disappeared as well. Determined to find her two missing friends, Mai embarks on a journey.
