Shadows, Before Dusk

The story follows Ares Buchanan, the ordinary young man who remained behind on earth as the rest of humanity chose to disappear into far realms to escape the disasters encroaching the planet at the world's sudden end. In far realms, it is peaceful but the races long settled there cannot be any more hostile to the sudden, uninvited guests. Realms are hurled into chaos as the flames of war are ignited. Meanwhile, Ares refines his skills defeating the disasters that were supposed by fellow humans to be undefeated. For him, it is a mere pastime. What will humanity have to say when they return and find Earth has been utterly rid of the dangers they were escaping? All that remains on Earth is a black-haired monk in a straw hat who seeks revenge against the people who deserted him and murdered his loved ones. Of course, vengeance itself can wait when danger is more than meets the eye. Here comes a danger that rivals Ares and the entire mankind.
