Hyakki Yakoushou

If you aren't a whiny lil b abt the animation, This anime has great storyline. episodes are only 4 minutes long but sure tell a lot of story. The artstyle is unique too. If you like historical anime, this one's for you.
The story is kinda unique in itself. Though its a normal yokai based anime. According to me it shows exactly what yokai behaviours would be like, unlike Shounen where they are used either for fanservice sake or as a villain.
The artstyle/ animation is just moving images here and there but it has its own feel like watching a sort of puppet show. The ... voice acting isn't bad either.
