Synopsis
According to legend, Atlantis was a civilization blessed with extraordinary paranormal abilities far beyond human comprehension. Their arrogance led Zeus, the almighty god, to sink the island. Even after the fall of their society, the descendants of the "Nereus" survived, adapting their powers to live underwater and establishing the Nereus Kingdom. The royal bloodline of the Nereids has transformed into spiritual beings, and their fifty offspring, called "Nereids," wield magical powers similar to those of fairies. However, the kingdom now faces a threat from Poseidon, the sea god, who considers their military strength a menace. To secure their survival, the king of the Nereids uses his unique abilities to send the Nereids back in time, though this causes them to lose most of their memories. Sadly, four of the younger sisters end up in the same era. This tale follows the carefree daily lives of these Aqua girls as they navigate their new world without much concern.
