There are yes. They are very thorough, they'll teach you how to fight the things we face here. Teach you what it is exactly you're up against. There is even a camp for those who want to become hunters and take those things head on after they have taken the classes.
I'm Juliet by the way. I've been here for quite some time so I'll try to answer you're questions as well as I can. My fiance wasis one of those Hunters.
