Youkai Watch, Jibaku Shounen Hanako-kun Recommendations
If you're into yōkai lore, you'll really love both Hanako-kun and Yōkai Watch. Not only are both shows about yōkai. They're also both mostly episodic with a new yōkai being introduced each episode. In both series the protagonist has to befriend the yōkai that are causing trouble for their classmates and family. (Well, just classmates in the case of Hanako-kun.) Both protagonists have a yōkai assistant who claims to be more knowledgable about other yōkai then he actually is.
