Fantasion 1: The Travelers

Fantasy

Ben is a nerdy college student majoring in engineering, who never imagined that he could become an isekai hero in a realm unlike anything he'd ever seen in story. When Ben finds himself in the realm of Fantasion with a tough girl named Riley, who fights in an underground arena to make money, he is in over his head. He and Riley must find a way to defeat a bloodborn orc with dark magic who can disintegrate anything. That will take a great deal of support from the people on the different islands, but not only do they not have support, they have enemies who are trying to kill them.
