Highschool DxD: Cursed

Kuoh Town is a lovely city in Japan, but it harbors a dark secret. A thousand years ago, the Hyoudou clan would become the victims of genocide due to their connection with the Dragons. The Three Factions would then go on to bury as much about this event as possible, keeping it secret and eliminating anyone who dares investigate further.

However, the secrets they hoped had been buried are threatened when after a thousand years, a boy named Issei Hyoudou shows up in Kuoh Academy, and is brought into the peerage of Rias Gremory, daughter of the Head of the prestigious Gremory clan and sister to the current Lucifer. And what's worse, along with the Boosted Gear, he's awakened in him a being that was never meant to return.

(I don't own Highschool DxD, just parts of the plot, as this will have a lot of original elements, as well as multiple OC's)
