After the final battle to save the world, the public had assumed Shadow had died. Even Team Sonic. Oh, how wrong they were.

You rode your bike through the woods, the city barely visible in the distance if you looked out of a tree. You were running away. Out of the corner of your eye, you saw a small black and red figure zoom past you. Was that Shadow, who you saw on the news? You found yourself riding towards where you saw the figure.
