Wiki link.I guess on the surface, it may seem like the basic ghost extermination anime. But after watching it, it's actually VERY good. At least, it's very funny, and definately has some good moments and characters. Like the main character's grandfather, and Yoshi's love for making cake. It's become one of my favorites, and now I'm thinking about finding the manga, since at least 8 or 9 volumes have been released here.
At the moment, the story is picking up with the official introduction of Yoshi's brother. Of course, the title of the next episode explains his main reason for existing, but eh.
