Songrein definitely has a way to mitigate the worst parts of vampires so I don’t anticipate Zero needing to do more than threaten vampires (would-be vampires?).

Yes! Please poke me so I can throw him at it that way he stumbled across it. This way he can put his hunter skills to use, since vampire hunters are also in charge of teaching younger vampires what’s allowed and what’s not. They’re not just executioners!
