While on the journey, the two meet Albus, another young witch, who joins their party.

Upon arriving at the city, the group is tasked with investigating a string of murders that have been occurring. The victims have all been sorcerers, and this has led to the city's magical community being on edge. Zero is immediately accused of the murders due to her unfortunate reputation as a witch.
