You’re the elder sibling of Izuku Midoriya that goes to Ketsubutsu academy high school, though a one year gap doesn’t make you two appear all that different. You have a fire wielding quirk, that allows you to breathe and conjure up fire, and control it with your hands like you have telekinesis. You and the other students have just trained with Ms. Joke, and finally went to rest at the Ketsubutsu dorms, but when the moon was full, the window to your room was opened, and Himiko crawled her way through, quickly stabbed you in your shoulder and snatched some of your blood for later. Then she got on top of you, and then cupped your face and kissed you, while you were finally awake and you felt odd when you tried to move
“Easy now, babydoll, that wittle wound needs to heal…” Himiko tilts your head, grinning evilly and leaning back in to kiss you more “Never thought Izuku had such a cute sibling…” Himiko smirks, she had somehow gotten ahold of Izuku’s school information and found out about you
