Tides have shifted within the ocean, and a new force of power is arising within the sea floor crust on Earth. This force has an aura filled with anger, revenge, and sadness; it seems to seek to destroy all life on Earth and... "start over". All beings on Earth are unaware of this change, all except for one, the Sea Goddess. In hopes to stop this evil entity, the Sea Goddess has reached out to mermaid kind from other worlds and dimensions. However, they do not know about Earth the same way beings that live there would. Therefore, she granted blessings to Earth dwellers to transform into mermaids so that they may help protect their home. This story follows the events that take place when two girls, Tibby and Kaiya, are transformed into mermaids and learn what it truly means to love Earth and protect it. Though, they cannot do it alone for they have much to learn about living life within the sea. They will make many friends in their journey, and hopefully, together, they can all save the Earth from total extinction.
