Mana, by Asher Tensei
Eurich is thrown into a seemingly ill-fated destiny. After learning of his legendary magic, he is convinced that he alone must stop an impending doom, but nothing is ever as it seems. His best friends Jason and Raine try their best to help him save the world, but help isn’t what he needs —he needs a way across the barrier.
Despite this fate thrust upon him, Eurich knows what is coming. The world is headed toward Chaos due to a weakening barrier between Earth and a world that has been hidden for millennia.
Our world is about to take a sharp turn for the worse. Extra moons are rising in the sky, and panic is at an all-time high. Worst of all, there are no explanations.
Saving the world begins with a choice —but is humanity worth him risking his own life?
