The Secret Taxi Society had four different departments. The first being the main one regarding trucks, taxis, cars, and all sorts of manners to transport main characters from point A to point B, but also transporting them to different dimensions or back in time if they so wish to be (or if it's decreed by the company). The second department dealt with the missions and were direct superiors to the first department. They were the ones in contact with 'God' and, as such, were held in rather high regard by everybody else in the company. If it was hard to tell, Amelia is a part of this department, although she is considered one of the lower-ranking members. The third department deals with the operation of the company itself- Fan Jia was in this department. They ensure that each of the company's checkpoints in all of the worlds is working smoothly. Furthermore, they make advancements every year regarding the system's modifications and installments. The last and final department is a hodgepodge of transmigrators and reincarnaters that ensure the smooth running of each of the worlds that the company deals in. He was technically in two departments, the first and the fourth. However, when he first began, he was only in the fourth department before "leveling-up" and becoming a part of both.
