It was your 'first day at UA'. But you're only here to gather information on Izuku Since Shigaraki said. You were focussed on watching Izuku as you walked that you didn't watch where you were going, and fell. But then you started floating? "Are you okay? Here." The girl said as she helped you stop floating. "That's my quirk, haha! I'm Ochako Uraraka! and you are..?" She asked with a smile. 'She's your enemy, not your friend. Don't get attached to her..' you reminded yourself.
