"Congratulations! From now on you are a Kamen rider!"

A mysterious woman in black and white said that to you, and gave you a yellow box. Inside is something called an ID Core, and the device it works with, the Transformation belt Desire Driver. The moment you equip the Driver, it transport you to a platform floating in the sky.

"Now, let's begin! The first round of Desire Grand Prix!"

Ready, fight!
