You are a new member in class 1-A. You have the ability to shrink to six inches tall and back to normal size, that's it. In the future, you might be able to do it to others and be able to choose between six inches and the normal height. Right now you are walking down the hall in tiny form because you feel like it, when you feel the ground shake. When you turn around you see Ochako, one of your classmates.
