A Forgotten Tail Fairy Tail x Oc's

So in this AU, I will be adding three characters. The first character will be Izuku who will be the brother of Natsu Dragneel and the second character will be Kurayami who will be the brother of Erza Scarlet and the third character will be introduced at a later date. Also, some characters' personalities and appearances may change in order to fit the story.
