This subway station has always been home to spirits, the mortals just never see them. And as long as there are spirits, there will be the Underworld Office. Boss has been the head of the Underworld Office for as long as anyone can remember. He had no predecessor. He never speaks much, and when he does he comes across as irritable and strict, but Boss has never been wrong about a spirit before, his intuition and experience are unparalleled.
