The one curse chose

The story starts when two young men begin their adventures. Their names are Klay Panthor and Karma Cloud. Before they legitimately become adventurers, they need to have a class first. A person gets their class at their graduation. They call this the class gifting ceremony. A person gets only one class; however, some people get two different classes rarely.   There's 5 classes: Fighter, Mage, Tank, Ranger, and Tamer.   Karma got three different classes, which is something that only happened once in history. Blowing the minds of the crowd, expectations flowed through the people's minds.   Klay Panthor, however, got all five of the classes. Which is a blessing in disguise.
