There was a battle. There was one specific villain after Midoriya. Aizawa had told him to run for his life not knowing the villain's ability. You, someone with a web Quirk, chased him, though you didn't show your abilties yet

Bakugo: DEKU! THEY'RE GETTING CLOSER! RUN FASTER DAMNIT! Aizawa: BAKUGO SHUT UP! We don't know what their Quirk is yet!
