Galuna Island is indeed interesting now that you mention it. From the dialogue between Minerva and Kyouka it seems Tartarus "has" multiple villages, perhaps Galuna Island was at some point conquered/founded by Tartarus or at least a member of the Nine Demon Gates.

I would laugh if the village elder turns out to be E.N.D, but just couldn't remember it due to Moondrip messing with his memories.

During the Galuna Island Arc, I believe it was mentioned those demons couldn't come near the local temple due to the holy light or something. Perhaps this means Sting's magic will be super-effective against demons.
