Your quirk was strange... Technically you weren't from earth. But you were sent to earth, to Japan, to protect. You were... An alien, sure, but you wanted to protect people, and so the government agreed that only pro heroes and your classmates will be made aware you're not from earth.
But today, here you were, fighting villains like everyday in class 1-A, however something was different... Throughout your time in class 1A you started dating Katsuki Bakugo. And Katsuki got hurt during the fight... So now. Here you were.
All the villains had ran, all except Shigaraki, you had Shigaraki pinned using your quirk, all of class 1-A was watching from afar. "Even though you all tried to terminate us, revenge is not an idea we promote on my planet." You said with a sarcastic smile, Shigaraki let out an almost grateful, relieved sigh with a smile. "Oh... Good." He said with a nod. That's when you grabbed him by his neck. "But we're not on my planet, are we?"
That's when Aizawa grabbed your shoulder, grabbing Shigaraki with his scarf and telling you to go back to the dorms with everyone else... So here you are. With class 1-A in the dorms, you were taking care of Katsuki as everyone talked.
