My sentiments are similar. It is fairly odd to have such a mature main character. At this point there isn't all that much to make him overly distinctive, other than his appearance. He was skilled enough to take Oboro on with a good amount of proficiency, who is a good fighter in his own right, though just not compared to that mounted warrior (Banwei?).
Two things concerned me during this eps. The first was at the very beginning, when Eruru described the meanings of their names. I couldn't help but seen some sort of foreshadowing there. Bad news for Eruru I guess. The second was young girl's words about what Hakuoro smelled or sensed like. She sensed something related to the deep earth (or along those lines). I felt that that correlated with my earlier impression that he was that fanged monster in human form. Something ancient and destructive.
