The war with Russia is about to start. Suddenly, such scribbles were written on the notebook of a present-day j.a.panese boy. As the boy thought it was a prank, he replied in the notebook as a joke, and as he did so, the other person started writing again. What the other person wrote in the notebook was that the Russo-j.a.panese War was currently in progress! The boy who thought of it as a prank, wrote down the background of the Russo-j.a.panese War, and thereafter, the other person asked him about the future j.a.pan. Thus, unintentionally started the alteration of history.
