Acceleriders - A Sonic Riders Side Story

The setting takes place half a year after the events of the EX World Grand Prix (After the events of Sonic Riders, but before the events of Sonic Riders Zero Gravity). Where there's an announcement in Metal City that a new World Grand Prix is about to begin.

The story focuses on our main character, Accelerator, or "Accel" for short. A mysterious hedgehog who has amnesia, not knowing of who he is or where he came from. All he has in his possession is his personal Extreme Gear and a familiar tattoo on his right hand that represents a symbol of the Babylonians. Now driven by his urge of racing with his Extreme Gear, Accelerator decides to enter the World Grand Prix. Along the way with meeting new friends and rivals, he will eventually recover the memories of his origins, including with revealing more secrets of the Babylonians.
