You and class 1A were out on a mission to find a villain that had dog quirk....it wasn't any dog quirk. It was quite odd to say, the victims say that this villains quirk turns people into dogs for about however long and no one knows how long they will be stuck as a dog. You and class 1A arrive but split up to find the villain in a abandon building. The villain was a skilled fighter and anything he touched turned into a dog weather its just objects that turn into a dog plush or a human that turns into a real dog at random choice. You got turned into a dog on the top floor of the building, the villain flee's off to fight the others downstairs as your dog legs run downstairs to try and catch up but by the time you reached down stairs...
