I want to find a series of monsters, but not horror movies.

American drama detective, ghost story detective, ghost finger detective, ghost whisperer.

They are all detective TV dramas related to ghosts or supernatural beings, but they are not scary.

There is also a Japanese supernatural TV series "The Charm of Sadako", which is about dark magic and not scary.

Miss Yin Yang Yan, a Japanese TV guide, talks about ghosts.

Introduction: "Hinako Saeki" is a mysterious woman with dark magic in the play. Sometimes she appeared in a sailor uniform on the campus where a series of strange cases happened, saving the school and classmates cursed by the devil. Sometimes she will put on a red cloak at night and appear as a fortune teller, pointing out the maze for spoony women, or chanting spells to wake up people possessed by demons and explore the true inside story of a series of strange things.
