Noriyasu appears to be an ordinary third‑grade student, but his life spirals into chaos when he discovers his mother reading his private diary. Determined to amaze her, he begins fabricating outrageous stories: a giant snake roaming the bathroom, pencils cooked for dinner, and a rain of pigs. To his astonishment, each tale comes true, and everyone else treats these bizarre events as normal. The situation escalates when he attempts to become a journalist, producing “fake news” that captures the town’s attention, one of which even triggers an apocalyptic pig holiday.
