Thousands of years after humanity expanded into space, the president of the small transport company Ashikaga Transport, Ashikaga Kouki, along with his veteran ex-military wife Kyoko, his younger brother Kiyoteru, and his unlovable android, Kiyomaro, were struggling to repay the loan for their purchased spaceship, Kanagawa. However, during a job, they are suddenly caught in a dimensional current along with the Kanagawa. The place they were sent to was Japan in the past, but it was subtly different from the history they knew. The three, who love themselves more than anyone else, decide to live freely in this world without fearing that history will change. (This is a work that I revised by beating up the prototype of a certain secondary creation that I wrote in the past. Although it is categorized as a historical genre, I think it is far from a true historical work, so if you dislike that kind of thing, please don't read it or just skim through it and skip it. Also, please note that people who were active in historical facts may die unexpectedly, or vice versa.) Episodes 5 and 75 have strong side story and interlude elements. The timeline is also confusing, so if you want a fast-paced story, it is recommended that you read only the main story continuously. (All seven volumes are currently on sale from MF Books!) ★ A comic adaptation has started ahead of schedule on Piccoma. (Currently, the comic adaptation is up to volume 5!)
