That reply by the anonymous, me, below was meant to go here. Mamiya...
Sadly we don't know but some in the comments said it's another shims warrior. But he has black hair and other than Raki no one else has black hair . It could also be a new threat because after the gate was sealed there hadn't been an enemy yet so I'm guessing it's about time for them to have one. But that's just my theory . I have read this story over 3 dozen times along with the raw and still have no clue of who he is. He only shows up at the very end of chapter 108. But I really hope it's another guy who wants Kou
suspicious indeed. but good looking and nice body built. just hope the update coming soon
