Izuku was chosen by Gran Torino, an old man who trained All Might. He was living in Hosu city so Izuku was interning there. At night, he decided to practice his quirk in an alley. He tried to get on top of a building by jumping to wall-to wall. Unfortunately he failed and fell down. Thankfully thrash bags under him softened his fall. He muttered to himself about controlling quirk,not knowing how it sounded outside. Izuku was working up something alright- It just happened to be a sweat this time!
