Noriyasu appears to be an ordinary third-grader, but his life spirals out of control after he catches his mother reading his private daily journal. To astonish her, he starts writing absurd lies about a giant snake in the bathroom, cooking pencils for dinner, and a rain of pigs. However, Noriyasu is the one who is shocked when his writings come true in reality and everyone else treats the events as normal. Things become even more chaotic when he tries his hand at being a newspaperman, producing “fake news” that become the talk of the town, with one story resulting in an apocalyptic porcine holiday.
