Sachi Yamamura

is a canteen employee and the user of Virus Gaia Memory.
==History==
After Sachi uses the Virus Gaia Memory to save herself from a hit and run, the transformation into the Virus Dopant is interrupted leaving only her consciousness fully enveloped in the Gaia Memory's corruptive influence. These events weaken the Virus Dopant, but also enables it to infect inanimate objects and electronics to compensate. 
This ability leads to the creation of the "Infected Car", a formerly wrecked SUV that infects a human with its deadly virus when phasing through its victims. When the car is wrecked by Kamen Rider W, the Virus Dopant begins using its physical form to exact Sachi's revenge on her ex-fiance who she learned was only a con man.
After discovering the Virus Dopant's vulnerability to heat, Kamen Rider W unleashes HeatTrigger's Trigger Explosion Maximum Drive to destroy the Dopant's physical body, causing the Virus Gaia Memory to eject from Sachi's body and shatters.
