Synopsis

One day, a woman named Chiyome Hesogakure visits the Nohara family with a 5-year-old child called Chinzo. Chiyome claims that she is the actual birth mother of Shinnosuke! But before Misae and Hiroshi figure out the truth, a group of mysterious ninjas come to the Nohara family and take Chiyome and Shinchan away to a Ninja Village! Chiyome tells Shinchan that there is powerful energy stored inside the Earth. To prevent energy loss from the "Navel of the Earth", descendants of the Hesogakure block it with a pure gold plug by using "Ninpo: The Art of Mononoke". The Earth will wither, and the rotation will stop if it comes off! Can Shinchan protect the future of the Earth and the "tomorrow" of his family?
