Story
Arga, who was expelled from the party he belonged to for the reason that he was "a Tamer, an unloved class," took this opportunity to have his level and such re-examined at the Adventurers' Guild, and there, he learned that he was a possessor of a second job that appears only once every thousand years. "Tamer," which makes monsters into allies, and "Fusionist," which combines and strengthens monsters - through these two jobs, Arga goes on to build the strongest party with monsters, the world's strongest female adventurer, and the vampire princesses!
