Ichiro Shino wins 4 billion yen in the lottery and retreats to his family home to avoid those chasing the money, only to be transported to another world. This is a spin-off of the "Lottery" series, focusing on Marie, the head housekeeper of the Istère mansion. She has been assigned as the town’s commercial manager and is involved in development projects, such as building a new public bathhouse. Other characters from the main series, including Baretta, Lise, and Zirconia, also appear and contribute to the story.
