Acting
Shūichirō Kiriyama works at the Limitation Task Force, the place where the cases which have reached the statute of limitations are destroyed. Getting bored of his job, he decides to find a hobby, because it seems important to him to have a hobby. So he decides to puzzle out the unsolved cases on his free time, helped by his coworker Mikazuki, who seems to have a crush on him.
After participating to a previous show where they have to bet or be challenged to any kind of competitions, the losing members of the Gaki no Tsukai are selected to spend 24 hours in a setting which they have no knowledge of the theme nor the course of the events. They are exposed to various absurd and crazy situations nonstop for 24 hours and must refrain from laughing. If they do so, hang-men appear and hit the rule breakers with a weapon (the weapon varies every year).
Junior high school student Hiroshi, who will only play with younger children, meets the young, taciturn Hachiya as he rides his bike. Shortly after, a strange friendship begins to blossom between them. But then Hachiya disappears, leaving behind only the puzzling words, "I am going to fight Demeking."
Kamei mixes humour, drama and, in this occasion, bits of horror to visualize the physical transformation in yôkai that the three main actresses undergo. Mihiro Iwasaki (Anri Ban) is a model extremely preoccupied by how others look at and think of her. Then, her nails start growing disproportionately until they become killing weapons. Michiko Yamane (Mariko Miyamitsu) is an unsociable university student and part-time worker in her early twenties only crazy for a hobby. At night she becomes a rokurokubi (female yokai with an extremely long and flexible neck). Finally, Mana Saeki (Haruki Ichikawa) is a last year junior high school student with a very bad character and very distrustful of all her friends, who metamorphoses into a nopperabo (yokai without face).
At the remote and hidden Shaolinji temple, Miyoko, also known as Shaolin Grandma , has practiced martial arts fighting techniques there for many years. When she is badly defeated by Ippon-ashi, her young and attractive rival, Miyoko is thrown out of the temple. Loosing her identity, Miyoko and her two Shaolinji apprentice misfits drift to an urban town.
