Synopsis

Atlas, the emperor of Ceria, invaded the once prosperous planet of Rennaya, searching for the Legendary Rennayan, one who could bend the will of all four elements, fire, ice, earth, and electricity.
Before the invasion, King Zenu gathered the blood of a billion of his people. Synthesizing and experimenting with it, all to create the perfect serum. Entrusting his young son, Osei, with the task of bringing his sibling to life, on Earth, by finding a human mother nearly as identical to his and giving her the serum.
Osei managed to accomplish the mission and kept the Earth safe, but he was captured in the process. Twenty years passed and Osei returned to Earth, as a runaway slave. Shaking Tobi's world with his real identity and awakening the dormant powers within him.
The only thing problem is, Earth is no longer safe...
