Anime & Witchcraft

I've noticed a recent trend in anime promoting witchcraft & occult powers, particularly since 2010's. Very open display of sigils, various demonic entities(depicted as morally ambiguous) & magical rituals(the Western occult type, not japanese). Chaos magic & summoning are particularly promoted. This doesn't look sinister until you research what these symbols & rituals are, which is likely to be blindly imitated by dumb teens (just like ouija boards lead to open possession through nothing but a plain cardboard with letters).
What stands behind this occult intrusion?

I had my suspicions, but now I know that you're retarded. You're using the fact that a ``25 best'' article written solely for SEO mainly lists more recent anime as proof of a trend? And your complaint about the use of cutesy ``demonic'' themes in modern themes is at odds with >>8-kun's assertion that pre-2000s ``demonic'' anime doesn't count because it was cutesy.
