The World Behind The Arch follows the story of Griffith and his classmates who, after being taken to a fantastic world by a strange light, part ways based on their convictions, with some wanting to return to their world, others, be able to live in the best possible way and that of the rest to take it all in stride and venture out into the world to have fun. It follows from the above that the role of Griffith drags into the background so that the story focuses more on two of his companions, Ziz and Garudo, two boys who have questionable ethics and morals and lack or have very little empathy for others, which causes that their trip around the world to become a cycle of degeneration in which they do something that ends up bringing endless pain and suffering for themselves and those around them.
