A war with Russia begins.

Suddenly, such a scribble appeared in a modern Japanese boy's notebook. Thinking it was a prank, the boy wrote a joke reply in the notebook, and then the other party wrote back again.

Amazingly, the person writing in the notebook was in the midst of the Russo-Japanese War!

The boy, still thinking it was all a joke, wrote down the historical progression of the Russo-Japanese War, which led the other party to ask for advice regarding Japan's future. Thus began the boy's unexpected alteration of history.
