Jiro has the quirk earphone jack, which means she can manipulate sound waves and hear basically anything. She also has jacks at the end of her ear Lopes, which she can control. Jiro has always really been the type to be down low and not want that much attention. Momo has the quirk called creation, she can create any inanimate object from her body's fat cells, Momo has usually been the top student type. You came to U.A a little later than the other students but everyone was impressed.
