We...Hunger (Highschool DXD x Venom Male Reader)

Everyone knows you by Y/N Warmonger. Your not entirely sure how you got that last name but your first name has been with you since you were little. You remember your childhood being full of family and fun. But then, at a certain point in your memory, you don't remember anything. You go to Kuoh Academy in Japan and don't talk to anyone because, as far as you could remember, if you are friends with other people...it doesn't take long before their gone thanks to your partner. One day, you find yourself walking home before seeing a boy killed by a woman with black feathery wings. Your not sure what is happening, but what happens after that, will change Y/N Warmonger, and his partner, forever.
