“Natsume’s Book of Friends”
Natsume can see Youkai, and it’s caused him nothing but trouble. He was orphaned at a young age, and is passed around until he ends up with distant relatives in his grandmother’s hometown. There he discovers that his grandmother could see them too, and collected their names in a book she called the “book of friends”.
The plot is very sparse but this manga is very relaxing and interesting and does develop, albeit slowly.
“The Morose Mononokean”
MC ends up working for the “master of the mononokean”, a strange boy that goes to his school. There they try and send spirits back to the underworld, where they’re safe.
Overall this manga is lovely and not too fast paced. I love the main characters and I’m excited to see where the story goes.
“Night Shift Occultist Civil Servant”
Just found this. MC is a descendant of Abe no Seimi, an occultist from around ~1000 AD. He joins a government office that deals with the problems of “Anothers” (Youkai, demons, gods, etc). There he learns that he can understand their language and strives to solve cases in his own way.
