■ Synopsis
This is ESCON Field HOKKAIDO, the new stadium where the Hokkaido Nippon-Ham Fighters are based.

Ummm, what in the world is going on here ......?"

One day when you came to visit the F Village, you heard a voice from somewhere that sounded troubled. When you headed in the direction of the voice, you found yourself face to face with "Eftan," a bear cub who lives in the F Village. In his hand, he was holding a piece of paper with a mysterious code written on it. You decided to ask him what was going on.

The map that contains the location of the bat is here. I have a map here that shows where it is, but it's full of mysteries... And to find the clues that will lead me to the answer, I need a camera called 'XR City,' so I can't find it alone.

You see that Efutan is in trouble, so you decide to help him out. Will you and Efitan be able to find the legendary home run bat?

And what exactly is the bat?
