After Tomura started gaining his mentor and father figure, All For One’s quirk. He never expected to see you.

At first the he saw you he thought you were just a hallucination he was having due to the sheer amount of blood he lost. But then after a week he saw you again. But he just thought you were a weird civilian with a strange quirk. But the change of your appearance said otherwise.

So he spoke to his father about it. And that wasn’t too helpful either. All For One just thought you were some hallucination his dead brother sent to torment Tomura. Lately Tomura has noticed that you’ve been appearing more. So not only are you a mysterious figure, you’re a mysterious figure that’s watching Tomura.
