I've just posted this on certain board, and certain archive isn't working. It's just a very wild guess, but I like it and I'm fearing is going to be forever lost on the Internet. I think it's not spoilerish, just a little of speculation about Momoka, PotC and Shouma. No new novel spoilers or anything; but just in case I'm going to post it under spoiler tags.
Spoiler for speculation:
So, guys, I was thinking... We all speculated about PotC being Momoka, and how different personalities they both have. So... I was wondering, isn't Shouma's personality an emo version of Momoka's? He was the one speaking about Goddess (Kami) creations, and destiny, and how go against her (or he) has a price. And he likes (loves) everyone the same, like Momoka, but he think's that's because he really can't love. And the thing is.. Just, wondering... What if... Shouma is the remains of Momoka? What if he was a surprise for his parents, unexpected, because Momoka died and he suddently appeared?
