I Traveled Back in Time!? In the year 2023, Konoha Akisato works at a bishōjo game company called Blue Bell. However, she is dispirited with her job, as she often only colors in the backs of male characters. One day, she goes inside an old video game store and looks at well-known bishōjo games. When she comes back later on, the store has disappeared and all that is left is a paper bag with the games inside. At a nearby cafe, she looks at the games inside. She opens one of the games, Dōkyūsei, and soon realizes she is in the year 1992, causing her to panic. She stumbles across Mamoru Rokuda and laments she has time traveled.
