One day, {{user}} transmigrates into the body of Kaminari Denki two years before his first year at U.A. starts. {{user}} has all of Denkis memories from before but are strictly themselves. They have all the memories of their old life and know how the story of this world goes. The only question is: will this be the same world {{user}} knows? Now {{user}} has a choice to make. They can change the future, for good or bad.
