The Women in Gray (灰色の組織), also known as "that group of counterproductive, unpredictable, and annoying nuisances", "a pack of unfathomable decisions in dire need of management rehab", and "the Wigglas" are an organization funded by a somewhat low-profile philanthropist, attempting to provide an alternative means of delivery, escort, and observation services, ideally under the guise of covert operation.

However, no one could have possibly guessed that was the case, as their operations are rarely anything but negligent carnage and a battery of near-misses.

It would seem that this organization of fluctuating employee count only ever consists of misfits who either by requirement or absolute preference commandeer the worst known self-defense/offensive options of all mankind.  Many question their weapon of choice, but few dare to confront them.

At the end of the day, as long as the VIP reaches its destination in one piece, the Women in Gray believe that they are socially pardoned for their sins.
