The Scarlett Family of the Lockman Kingdom itself had a fully formed team composed of auxiliary professionals. They could create any magitech item that any reigning ruler desired, such as the Merit System and Demon Hunter Monument that His Majesty Mureya wanted for the Demon Hunting Team.
Every member who joins the Demon Hunting Team can receive a piece of jewelry similar to a Battlefield Recorder. It can be a belt, a wrist guard, a forehead ornament, or any other item that doesn't affect combat power.
These Battlefield Recorders can record all the information after the wearer kills a demon. After evaluation, it converts into merit, then the data is transmitted to the nearest Demon Hunter Monument, and finally synchronizes to all the Demon Hunter Monuments so that the kingdom's residents can see it.
