Guin

The title character, Guin is a mysterious warrior with the head of a leopard. He stumbles upon Remus and Rinda being attacked by soldiers and defeats the entire unit singlehandedly. He remembers nothing of his past, knowing only his fighting instincts, what he believes is his name, and a word: Aurra. Guin is often put in position where he will suddenly have a skill he doesn't know he has. As of Vol 4 of the novels, he starts to realize that he really is part of the Destiny reshaping the land. He's inhumanly strong and knowledgeable about battle strategies, causing the Mongauli army to fear and respect him as a warrior, as he will often set up various battle scenarios and jump into battle himself and show off his inhuman skills.
