When it comes to beauty, the differences between male and female are meaningless. In fact, it’s completely natural for a beautiful boy to love both men and women. I’ve been studying history, and the moral standard that only a man and women can have sex was a later addition.

I thought I might find someone like me if I could see the data on every imperial citizen. I had hoped to find someone who could understand me even a little, but this is amazing. There isn’t anyone. I’m the only one like this. I feel like I’m standing all alone below a never-ending expanse of blue sky. It’s refreshing but horribly worrying. So this is what it means to see everything.
