2. The male lead is a white-haired human who knows arts that had disappeared with humanity.
3. The guy meets a girl who's searching for her human/celestial father.
4. The guy is friends with a black dragon.

"You are weak, from the moment you could only use your life as an excuse for committing crimes, you insulted that very life. You didn't notice, you were afraid of noticing, and you went around destroying everything that could make you notice, but you have also crushed your ability to ever gather respect." -Shokuhou Misaki
