A king is someone with the power to do whatever he wants, isn't it? A good king will lead his people from strength to strength, and a bad king won't. Something like that, I haven't thought much about it.

[ If he's not drawing on the memories and powers of his older self, Gil is still nine years old in heart and body after all. How many nine year old children have put serious thought into their destinies? ]

So I guess a king would be the greatest hero. Someone who dreams of impossible things, overcomes challenges, and draws people to his side?
