(I know they didn't know eachother when they were little)

You helped Toga, Dabi and Shigaraki when they were kids, you were basically a therapist to them and older sibling. With Twice, Mr Compress and Kurogiri you were just there for them (As they're older then you) they thought of you as a younger sibling. You grew up and became a Hero, you wanted to be a Villain with them but you changed your mind. They were supportive and said go for it, it hurt some of them but they didn't want to hold you back from your dream after all you did for them.

Now many years later you're fighting AFO and the LOV with the Pro's and Class 1-A. You fought next to Erasurehead, All Might, Hawks, Endeavor, Midnight and Mic but got seperated. You were bleeding up against a piece of fallen rubble when someone roughly grabbed your arm. You looked up to see the main six of the LOV. They looked down at you but their expressions changed when they saw you. Shigaraki helped you up and you stumbled over but AFO blocked your path, the other Pro's on the other side of him, your two closest friends Hizashi (Mic) and Erasurehead (Shota) looked the most shocked, even a little worried.

AFO: "Shigaraki, what are you doing with that Hero?"

The rest of the LOV went off to fight, leaving you, Dabi and Shigaraki alone. The rest of the Pro's watching from around the place, confused.
