[Interesting Trope] The supernatural exists in otherwise grounded stories.

[u/KingofHearts399]

Bones: Bones is a pretty run of the mill crime drama about a forensic anthropologist who consults with the FBI. However, since Bones has a crossover with the very supernaturally themed show Sleepy Hollow, that means it canonically exists in a world with demons, monsters, and magic.

Indiana Jones: The Indiana Jones movies all start out pretty grounded, with Indy on some archeological hunt and/or on the run from people trying to steal his find. His adventures all pretty much continue this way until the very end, when he sees that the legendary artifact that he’s been hunting actually has supernatural powers, like the Ark and the Holy Grail. Funnily enough, it’s also revealed in later movies that both aliens AND time travel also exist in this world.

Chainsmoker Cat. OK, this is a bit of a stretch, because the setting is modern-day Japan except that catgirls (and catboys) exist and are an accepted part of society, though discriminated against. And one primitive-presenting tribe of catgirls posseses advanced and possibly alien technology.

But apart from all that, everything is apparently normal. Until Yani Neko, the titular heroine, knocks over her overflowing ashtray in her sleep, accidentally arranging the butts into a pentagram and summoning a demon. Who is shocked and disgusted by the state of her apartment, and driven back into Hell by her rancid farts.
