Well he's quite literally titled the Scarlet Crusader. He's a very serious individual when it comes to combat. But assuming he's decent friends with the people he's travelling with. Expect some amusing combats. Think of a Russian Bear. Friendly, and cheerful, giant of a person. But protective, to a point where breaking a skull into a thousand pieces to save you, is a sign of friendship.
Basically, just a very strange, and at times aloof person. Since this would be his first time, not apart of some crusade, which is a bit odd to consider, since he's around 37-40 years of age.
