@Zombehs: Having thought about it a bit, I was wondering if Kuro's abilities could maybe be toned down a little. I'm fine with him being stronger/faster/tougher than a human, maybe even to the extent where he's capable of clearing some smaller monster dens on his own, but for the most part, it should take a group to clear one out.
 
@Dharc: He looks good for the most part, there are a couple of things I found a little odd though. Firstly, the name. I'm guessing he's not from Himoto, but...even still, I find it a little strange that his name's a kind of fairy, especially given that they probably exist in the setting. The second thing is the appearance. I'm not going to say you need to change it or anything, I just think I should point out that he's going to look pretty out of place walking around like that.
 
@Rune_Alchemist: Looking at your character's backstory, a couple of things stand out to me as potential issues. Firstly, it wouldn't exactly matter if the elder had missed a few when he cleared that den out, since the monsters keep coming back regardless. By the same token, her personal goal's...kind of impossible. And secondly, while some dens might be able to be handled by one decently experienced hunter, for the most part, it should take a group to clear one out.
 
@Diggerton: Ability-wise the changes look fine, although I feel I should mention that if the Kusanagi's meant to be the same one from the Imperial regalia, then it's not actually a katana.
