Interested. I can go for a goofball 'we could tell adults, but no, we must handle this ourselves, fellow teens!' plot. ;)

FWIW, I think the plot is more effective in a bland, generic, cornfed American town. It allows to be thoroughly ironic on who the Demon Lord is and invoke all the tropes of a high school setting, such as dickish 1980's style bullies (like William Zabka in every role he ever played). I know what I'd pick for the Demon Lord, as well. It's an amusing idea.
