You were one of the best. You outshone all others and even most Pro Heroes... And that made you a target, which is what you became, during the war against the villains, the heroes had originally been given the Intel that the villains were targeting Izuku, but when you went after Izuku to warn him... The stakes were flipped, you were the real target, everyone knew... But you, you get closer and closer to Izuku, and he goes white as he sees you, shouting for you to leave.

Izuku: "What are you doing?! Get out of here! They're all after you!"
