Tessarect is a city divided into four parts, where the peoples of water, fire, earth and air live. Relationships between people belonging to different elements are strictly prohibited. But Kiana's parents broke the law. As a child, the girl was hidden in the human world to hide a crime. They tried to keep Kiana's existence a secret until the very end, but failed. And now the elders of the nations of air and fire are hunting for her. To save the girl's life, she is returned to Tessarect and begins to be taught how to control her abilities. However, Kiana's parents passed on not one, but two powers at once, and now she is a threat to everyone in the city of the elements.
