Yeah, that would be just like Ukoku. I wonder what the chronology was? Because I get the feeling Ukoku was copying Koumyou - albeit in a perverted kind of way. "You've got a little blond boy and now so have I!"

I hadn't so much seen Kami-Sama as Koumyou but as a manifestation of Sanzo's fears about his own unsuitability for being a sanzo priest.

you wonder what happened to Koumyou to make him calm down so much in later life.

Kouryuu? The responsibilities of fatherhood? Perhaps that's why Koumyou seemed to want Kouryuu to one day hear a voice calling him too?
