I want demons to appear in my story, but having them originate from Hell was never appealing. Anyways, these "demons" are summoned to Earth- a planet that's only just discovering magic.
They are- in essence- still demons. Things like holy trinkets and devil's traps still work on them. But what about Hell? I'm not very sure how else to put it.
I could probably get away with not touching on this at all in my story- humans never learn the truth (aside from main characters) about the demons' origin & just assume they came from Hell. But some deeper world building couldn't hurt.
EDIT: To get a better idea of the tone- humor is really important to me. I draw a lot of inspiration from things like Kill la Kill and One Punch. Sensible nonsense. That said, Yes: I'm comparing a world where demons come from a planet vs a world where demons come from hell. However, this Earth has never encountered real demons until their discovery of magic.
