Whether we like to admit it or not, nothing lasts forever. The world slowly came to realize that as the turn of the century came, and so came the rise of Demiases. People were being born with developing abilities and we didn't like it. Humanity was afraid. So, as expected, we began to riot. Riots, murders, protests, everything to stop the protection of these new beings. Humanity doesn't like what it can't understand. At the head of it all, new tests are being done to try and convert the Demiases into normal human beings. Not unique, not beautiful. Now the world will have to deal with what happens when the most powerful Demias alive slowly starts learning to control his abilities, and they're in for a hell of a ride. The heartbreaking reality will finally settle in and the cruelty of humanity will still refuse to cease.
"Don't say that. Everyone leaves eventually, just..."

"Okay... I'll stay. I promise."
