There was demon hunting and there was monster hunting. Some could argue the line between the two was pretty slim, probably subjective, and possibly even entirely non-existent, but Joss Landon liked to think that he kept a pretty firm grasp of what his real prey tended to be.
He, and all his family, were demon hunters. Sure, some monsters were bad, but some weren't entirely nonredeemable.
It was why Joss often ignored monsters and those that asked for him to hunt and kill them. Unless said monster was actually being a problem and obvious threat to humans. Then all bets were off and he could take a little time out of his demon-hunting for some good old-fashioned beast killing. Life would get boring if he didn't get the occasional change of pace.
Lamia and naga were pretty straight-up monsters to him. They weren't like werewolves or even some vampires - poor saps that had been human once upon a time and could sometimes still be pretty human-like in their lifestyle. No, these things weren't really human at all and never had been.
Joss had been trailing a particularly nasty demon for days, studying his prey, trying to close in on the cursed thing before going in for the kill when the demon least expected an attack to come. Stumbling onto some poor fools with a snake problem had been entirely unintentional. Just a case of blind luck. Whether that was good or bad luck remained to be seen.
As he heard the pained sounds of something, he was leaning towards it being bad luck. Just in case things got ugly, Joss pressed his thumb against the sharp edge of his book and felt a few drops of blood well up. A dark, wicked-looking scimitar appeared in his hand as he approached the sounds that had put him on edge. The demon hunter was being very cautious, as he didn't want to end up with any sharp things sticking out of him today. Including Lamia fangs.
