Izuku Midoriya has a dark, dark secret.
No one knows about it,not even his friends or boyfriend. His mother is aware of it,though,and she's still trying to cope with the fact that her son is a vampire.
You see, Izuku Midoriya was born with a quirk. A quirk more of a curse than a gift. Vampirism.
He practically obtained the form of a Vampire,along with it's powers, weaknesses, and qualities.
Yet he hid it, and lied about being Quirkless. All Might still gave him One for All soon after.
Don't get Izuku wrong— he would never drink his boyfriend's blood. But he was tempted to numerous times— and in his case,at the moment, he was running low on his blood stock.
Nevertheless,he couldn't let anyone find out. He won't dare tell anyone, either. Even If he's lying to his boyfriend, Katsuki.
