A small country town. Recently, the town has witnessed many strange incidents. A yokai kindergartener O-O-O-No Shinnosuke and his yokai father Tamatama Dad arrive in town. They are said to be looking for the yokai Big Butt Mom who has run away from home. When an elementary school girl Fumie Sakura is suddenly attacked by the mysterious Fuzzy Wuzzy, a superfluous-hair yokai, Shinnosuke goes to her aid. Their encounter is the start of the greatest yokai case in the small town's history.

Oban was the villain of a special effects show that became a huge hit. Oban figures were also popular for a while, but the boom faded quickly and the unsold figures were set aside for disposal. Then one day, the Oban figure is struck by lightning and brought to life. Burning with vengeance against the humans who abandoned her, Oban manipulates the other toys to attack people. Meanwhile, Oban's nemesis, the Masked Chukonen, is also given life at the same time. Masked Chukonen really looks like a sad middle-aged, metabolic-syndrome sufferer, but when he eats instant noodles he is charged with energy and transformed into a superhero. To bring back peace, he joins with Shinnosuke to battle Oban and her crew.
