There is a loose theme throughout the series of the "Thriller Restaurant", which is introduced in the first episode. The remainder of the series is a collection of ghost stories reminiscent of the Scary Stories anthology and Kwaidan.

Each episode is broken up into three "dishes", namely the Appetizer, the Main Dish, and the Dessert. The "Appetizer" is a short story featuring something supernatural, such as ghosts, spirits, or similar. The "Main Dish" is a longer ghost story similar to the Appetizer, usually with a twist. The "Dessert" is a ghost story told by one of the main characters while playing Hyakumonogatari Kaidankai (百物語怪談会 Hyakumonogatari Kaidankai^?). These involve characters not related to the series and end with some sort of a moral lesson. From the thirteenth episode onwards, a fourth story is told while the ending score plays, replacing the original animation; these stories have a scary picture shown when the music ends.
