God of Death's Academy

The world you all know has long since fallen apart, your friends and family are now either vacationing in Heaven or rotting in Hell. But for the chosen ones, the Creator has awakened a new World for them based on magic and science. A world occupied by three nations, with different homes and bodies. Intelligent scientists in the sky, creative craftsmen on land, and artists bathed in beauty below the ocean. 18 years have passed since the birth of the first generation of the Island of Kaput. At the age of 5, everyone was to be sent to the Main Island for our study since there was no school here when we were a kid. But now, the God of Death made us a college to prepare ourselves for the unending danger brought by the people from the unknown world filled with nothing but the Void. This is the story of me and my classmates trying our best to be graduated as members of the Guild, an official organization handling the matter of monsters and dangers from the Void.
