Reincarnated as a black dragon, all for freedom!

Reincarnated as a black dragon, I arrived in a Western fantasy world. Starting with ancestral traits and a talent for devouring, my growth rate was maxed out! Dragons reach adulthood in a thousand years? I directly broke through to become a legendary black dragon in five hundred years! From Dragon Valley Kindergarten onwards, everything is for freedom! Female dragon cubs want to cuddle? Sorry, I'm too ugly to refuse! Dragon Girl Sister!! Mine! All mine!! "I was born to the sky, I pursue freedom!" Dragon Valley too boring? I simply left for the continent. Elf Saintess, Imperial Princess, Shadow Queen, I just want to give them freedom!
