The main duo for "The Herald of Death" is the butler and maid team, Kyle and Selena, who each have their own signature weapons.
Kyle Concord is a bit of a gun nerd thanks to his (definitely-not-an-)obsession with airsoft. As such, his favorite pistol is a bit of an odd one: the Volkspistole, AKA The People's Pistol, is from the mid 1940's and was made to be a cheap alternative for the Germans during the later period of WWII. To Kyle, it just looks cool and underrated, so it was his sidearm of choice when he saw an airsoft replica at a tournament when he was just fourteen.

As for the main heroine, Selena is gonna end up using the Bittner Repeating pistol. She's much more of a fighter than a gunslinger, so it's not her go-to weapon, but it's always handy to have something to shoot back at distant enemies with.
It has a ring-trigger that acts in place of a hammer; it can be pulled back to charge the firing pin, and then the real trigger can be pressed to shoot, or you can pull the ring back and fire in one swift, heavy trigger pull. Fun fact, it seems these ring triggers were not unpopular during the late 1800's, but they never replaced your average hammer-fired pistols.

These weapons won't get their time to shine for a while, so subscribe here to see when they finally get called to action:
