The Morose Mononokean

Ashiya Hanae is a high school student who finds himself plagued by a persistent, fluffy yokai. Desperate for help, he encounters Abeno, the owner of the 'Mononokean,' a tea room that serves as a gateway for yokai to return to the spirit world. The series follows their partnership as they help various spirits resolve their issues in the human world. It is a charming, lighthearted series that focuses on the emotional needs of spirits and the growth of the two main characters.

Its a great choice for those who want a relaxing, supernatural-themed show.
