For me this instantly read Buffy the Vampire Slayer (if it weren’t for the change of town name, I could have thought this was for the Examples section):

• Highsdale – Sunnydale
• Demonic visitors – demons and vampires
• Hellgate – Hellmouth
• High school student – as per
• Lineage of the Huntresses – lineage of the Slayers
• Apolcalypse – as per

You didn’t mention a gender, but Richiev used ‘her’ in his rewrite and I wonder if this is because it suggested the same to him.

Don’t get me wrong, this is the kind of thing I can watch over and over again – in fact it’s the type of thing I’m trying to find an angle on at present. ?I suppose that’s my point, I’d be tempted to rethink an approach or angle where you’re offering the same kind of thing, only different enough to stand alone and peak someone’s interest.
