# Title Synopsis
1 Police Cadets, Report for Duty!
The story begins with a flashback when Beagle, Fang and Kroos began their police career in Tkaronto, Columbia. After resolving a gang fight in an Infected residence area, the trio meet a Lupo girl named Alva and the leader of the "Red Hands" Thunderstone. Thunderstone admires their ability and eventually befriended them. One day, the trio notices Alva stealing the goods from a Mama John;s businesman Splitears. From Alva's words, Splitears has been selling fake medicines to the locals. Being enraged by her words, they are about to arrest him, but this is soon interrupted by an arriving Catastrophe.
2 Incurable
The story shifts its time back to ten years ago when a Catastrophe in the form of a blizzard hit Tkaronto and young Alva was forced to be separated from her mother after the city barred any Infected Messenger from entering. While working inside a local Originium refinery, she encountered a Perro boy who desperately wanted to sell his crude Originium ingot to buy a "cure" for his dying mother. Upon telling him the truth about Oripathy, the boy collapsed in desperation, and Alva comforted him by giving him a canned food.
