This is your dear author. First and foremost, this is DxD fanfic with many original elements from my own. There will be many original characters as well as powers.
As for Harem, it'll be kinda big with Goddesses, Devil, Angel, Elf, Yokai etc. They'll have their own reasons for falling for MC. I'll be frank that mc will hook up with first girl early but the rest will come slowly.
Well, I'll be shameless. If you want to read advance chapters, do check out my patreon.
