{Izuku}
Izuku wakes up. Or more accurately, Izuku is woken up. By a dreadful pounding in his head and so, so many sore muscles. The muscles at least can be ignored with the ease of long practice.
As he sits up he thinks he sees somebody out of the open window, and tries to sneak his way to the door of the cabin, electrical arcs jumping around his body in preparation.
As soon as he leaves the building an old man with a walking staff sees him and walks over to him, rambling gibberish. "I don't know what you're saying." As the stranger reaches for him while saying something else in gibberish, Izuku darts away, One For All ramping up until his entire body feels like pins and needles.
As soon as he's out of sight Izuku releases his quirk, nearly crying in relief when the pins and needles partly fade away. He stays in the abandoned building he ran to for a bit, hoping that the stranger doesn't follow him.
Maybe he shouldn't have run like that. Or at least not use that much of his quirk. Maybe he can get to a point that it's painless to use that percentage. How much was that anyways? Five percent? Probably not. It's All Might's quirk after all. 'In all probability I used maybe a percent' Izuku thinks, not realizing that it was closer to three.
As Izuku explores his surroundings to try and figure out where he is, he's suddenly jumped by another of those red goblin creatures. Izuku manages to clumsily move out of the way of its wild swing, wincing at the sound of the wooden club hitting the ground with a force that could break a bone, if not outright kill if the blow lands in the right spot. Izuku swings a sloppy, desperate, wild punch in return, making contact with the creature's large nose, making it flinch back.
Izuku starts to run away, only to see five more of the goblin things running towards him in a wide semicircle. Panicking, Izuku keeps running towards the closest one, hoping that it will slow down enough for him to run away. It doesn't work. The goblin thing jumps at him instead. So Izuku does his best to duck under the flying pig creature, flinching as grasping hands pull on his hair, pulling him to the ground. A green spark reminds him that he has a quirk now, so he pulls on the newly familiar hot-cold-static of One For All. He kicks at the goblinoid and scrambles to get away from it, dashing deeper into the forest.
He sees a girl standing at the edge of a clearing with a pile of rocks in the middle. She looks about his age, if maybe a year older, with blue hair done in a simple ponytail, and is squatting in front of a weird plant, collecting it.
"Hey!" He calls out to her, running towards the stranger. Apparently this spooks her off, and she leaves, almost forgetting to grab her basket of plants. Soon, though, Izuku understands. The boulders move and shift, pulling together under some unseen force as it staggers to its feet. Izuku bolts in a different direction than the girl, if shes running then she probably won't be able to fight it!
