The identity of the Road Dopant has been made clear, and Kamen Rider W is here to save the day. But questions still remain. Who is Tokime, and what happened to her memories?

When a popular video game company's idol-spokeswoman/head developer starts receiving death threats, the Narumi Detective Agency is brought in to protect her.

The final confrontation with the Meganeura Dopant is at hand, and just as Tokime starts to settle in at the Narumi Detective Agency, a threatening force in the city's underworld begins to stir.
