After reading this last chapter I'm sure that Rokuro is Abe no Seimei son....Initially I thought he was Seimei himself, but no we no that Abe no Seimei is a woman, and then Rokuro flash memory of his mum saying I'm waiting for you in magano...and the red eyes...I'm sure he's the son...so he's really a badass much more then Tenma...
way to go Shunshin....
