Reapers, Inc.: The Hunter

It's been five years since Brigit Malone joined Reapers, Incorporated with the intent of keeping a promise to her partner, Maggie, to always be with her. Since Brigit's death, though, Maggie has started to move on with her life, leaving Brigit with little choice but to focus on the business of being the Assistant to the Grim Reaper.
Everyone is suffering from burnout and John Blackwick, the Grim Reaper, wants to go on holiday. This means a temporary promotion for Brigit and she decides to ask Katuri-Buttercup to sit her chair while she fills in for John. Brigit thinks it's an easy solution until Katuri-Buttercup goes missing.
In the effort to find the missing Reaper, Brigit comes across a ghost town and the soul (the hunter)responsible for Katuri-Buttercup's disappearance. Brigit is ordered to recruit the hunter or cross him to his eternal fate.
