Upon the successful completion of the Trial, a civilian would undergo class bestowal.
There were a lot of classes in existence in the world of Las Felipinas. However, most of them— no matter how strange the class was would still be classified by the Church that governs the civilian that had just become a Predator.
Let us say that you are a civilian that obtained the class called Magic Swordsman.
Now, the word Magic alone should be enough for one to realize that the class could use Magic. Does his class belong to the Mage-Type, then? Nope! Why? It was because of the Swordsman at the end of his class name.
If you add Magic and Swordsman then you would get the two classifications, namely, "Mage" and "Fighter". In short, the person in question has a dual-affiliated class. Of course, dual-affiliated classes were rare. After all, a god or goddess could be lazy and just randomly give the civilian a niche class such as Street Cleaner.
