Search For The Lost God

A boy named Hyuma who was separated from his sister, Yuna, due to the appearance of a mysterious magic circle and forcibly brought Hyuma to another world.
To return to his world, Hyuma must find The God Eaft, but the possibility is very small because God Eaft has never shown his existence in the world, even after the world was colonized by Foreign Gods, God Eaft still doesn't appear to save his world.
On the other hand, Hyuma also has to adapt to his new life in the world he currently lives in, starting from the Level System, Super Powers, Monsters and Life bound by Mana, but Hyuma's condition is unlucky because his level cannot rise up and he stuck at Beginner level.
