Kohaku doesn't have any gender.He admits it himself.So it's up to ther reader whether they want to portray Kohaku as a he or she.
Yeah that's right, I think it's mainly because angels don't need to reproduce
Kohaku is a female :) same with the arch angel of wind is. Got confusing when the books I have say her but on this it switches to he so even I was confused but the ending is heartbreaking but I'm glad they're together. :)
