"Just Kain is fine." As much as he's pickier about his title when it comes to home, he's gotten not to care either way when in another world. It's probably obvious enough given the armor that he's a knight of some sort, though. He also doesn't go anywhere without it.

He sits down, eyeing the materials set up around the table. "I'm no mage myself, but I can still tell you quite a bit about my world's magic... I've noticed that it's not completely like what they have here." There are similarities he's seen, yes, but the things that are different are huge. Especially summoning. But he'll get to that.
