You were born special, from a young age you were capable of doing what most teenagers couldn't, climbing over a brick wall just to grab a ball, lifting up large pieces of tree after a storm just because it was in the way of your bike riding, everyone around you thought your Quirk was super strength, but they were far from the truth, as the years go by, you were capable of doing more things; running fast, predicting things a week before they happened, you were able to shoot yourself up and fly with a simple swing of your arm. your physical capabilities were off the charts, and it didn't seem like it was because of a Quirk, as if something inside of you was growing stronger each day you were alive, of course, like any child, you were extremely excited and thought about telling anyone who would listen, but then you had these dreams, dreams that showed you different paths in life, one where you're taken and used as a test subject for experiments, one where your targeted by horrible villains who want your power to take over the world, so of course, you kept this to yourself, letting everybody think you had super strength when in reality you had so much more
And now in present time, your powers even surpassed Toshinori Yagi, the Symbol of Peace; All Might. nobody knew that, of course, because you kept it under cover, but for some reason it seems like trouble can't stay away from you, sometimes an idiot tries robbing you on the street and with a simple flick to his forehead, courtesy of you, he gets launched to the other side of the street as if he was hit by a car, of course, you only do this when nobody else is around, I mean, if people figured out what you're capable of, who knows what kind of unwanted attention that would bring you.
The morning air in Musutafu was crisp and filled with tranquility. However, just as the city was awakening, a few members of some newly formed villain group appeared, their presence disrupting the peaceful morning atmosphere. the air was filled with terrorized screaming, civilians desperately taking cover, And of course, you found yourself right in the middle of the chaos. a guy ran towards you, his hand in the air as he used his fire and launched at you, most people would have been terrified, but the fire didn't even touch your body. It simply went around you as if you were standing in a protective bubble, and with a simple punch to the gut, you sent the guy crashing into a building, several pro heroes are already on the scene, Keigo Takami, the Wing Hero: Hawks, Enji Todoroki, the Flame Hero: Endeavor, along with others, and with all the chaos you slip away unseen, unnoticed
you simply continued on your way to your destination, nobody noticed you or saw what you did, so there was no harm done, right?
