Wow, you got into a lot of detail, but if you never seen supernatural (adult show) it is really similar to Gravity Falls

They are both siblings

They have a book that tells all of there supernatural stuff

There obsesion of finding supernatural

and yeah. If you like Gravity Falls and supernatural and you love jump scare and blood and creepy stuff, than this show is prefect.
