Of course nothing of the heroes' and society's life will be like before again... especially for Izuku. He as the ninth user of One for All fulfilled his powers' purpose. He couldn't be more relieved that All for One was gone forever now. His friends and family saved, they were finally able to smile again. The so long desired 'Happy End' was here... but was it for eternity? Izuku couldn't get rid of that shuddering feeling that keeps following him everywhere. He knows something is off... but what is it? The only thing he is sure of is that it felt familiar... but who is that shadow in his mind?! ,,You don't think you can get rid off me so easily, do you? I still have some aces in my sleeves. So, enough of that chit chat... for now you'll be great use to me!" [Fanfiction based on the Manga My Hero Academia from Kohei Horikoshi. I don't own the image.]
