I've never heard of any 'Sparda.'

As for a Demon Hunter... I assume you aren't referring to Devil Slayer magic. As far as I am aware, the worst of the demons are gone, and the rest have been relatively well-behaved. Our main problems, aside from the fissure, are a group of anti-magic radicals, and an insane vampire who is angry over an unfavorable election result.
