The manga, serialised in IKKI, is based on a seinen manga written by Kikuchi Naoe and Yokomi Hirohiko. In the story, a manga artist is tasked by her boss to accompany him and a travel writer on multiple train journeys across Japan to produce a manga about the experience. The twist is that the manga is entirely non-fiction, and the artist merely documents what happens without any embellishments. The lack of drama is acknowledged in a disclaimer at the beginning, but the train journeys themselves remain entertaining, with the travel writer, who is a train enthusiast, micro-managing every detail, while the artist is cynical and sarcastic, mainly interested in the delicious train station bento box (eki-ben). The manga maintains a realistic feel throughout, with the train journeys likely to be familiar to anyone who has travelled by train in Japan. The artist keeps the pacing consistent and adds small tweaks to maintain enjoyment. The story also features real-life people who appear because they are fans of the manga. Readers can also learn about different, lesser-known train lines and stations in Japan, including some that look cool. However, the trips are often surreal, planned to check off boxes without considering the experience. The travel writer's goal is to visit all 9,843 stations in Japan, providing insight into train-enthusiast culture.
