In a small publishing house on the second floor of an old building, the lives of its employees intertwine.

The story takes place in the town of Most City in a certain country. On the second floor of an old building is a publishing company that puts out a periodical called Delusional Monthly Magazine, a science magazine featuring articles about shocking, bizarre events and inexplicable phenomena that make even scientists throw up their hands in defeat. Its staff consists only of a beautiful editor-in-chief and her one editor, Taro J. Suzuki, who are joined by grade-school-aged assistant Jiro Tanaka and his dog, Saburo. The editorial department is always empty, and Taro, Jiro, and Saburo are usually hanging out in Rock, a coffee shop on the first floor. One day, the scientist Goro Sato visits them for a consultation, and therein lies the beginning of an outlandish new story.—Crunchyroll
