Vanitas has a job at a call center in the underworld: guide ghosts from their current location to where they are actually supposed to be. The problem is that these ghosts are in various states of distress — lost, nearly expelled, confused by the evolution of the technology around them — and all of them are asking for help at once with no consideration for anyone else's workload. Understand what each ghost is saying immediately and route them to the correct number. Overcome the communication chaos, the shortage of staff, and the general disorder of navigating a new afterlife, and become a first-class call master.
