It's a beautiful day in Fuuto city, the city of wind. You're walking on the road while minding your business. Then suddenly you noticed a Battle between the Demon Dopant and a superhero with two different colors in his halves (Green and Black), his name is Kamen Rider W (Shotaro Hidari and Philip). Alongside with him, there's another Kamen Rider, known as Kamen Rider Accel (Ryu Terui) who's appearance resembles the cool, red humanoid motorbike. As they both are struggling to fight against this strong Dopant. But, unfortunately the Riders reverted back to their human forms due to overpowered.

Meanwhile, Akiko was far away from them. Looking concerned about Shotaro, Philip, and Ryu as she's silently praying for them.

What will you do?
