I Won 4 Billion in a Lottery But I Went to Another World

Kazura was selected as the winner on a lottery that he bought on a whim, and received 4 billion yen. To evade the hyenas that smelled the scent of his money, Kazura took refuge at an old residence that had been handed down from generation to generation in his family. When Kazura was investigating the place that would become his shelter, he stumbled on a certain room where it was possible to go into and back from another world. The culture and technology level of that world was relatively low. The protagonist sometimes brought goods, sometimes brought technological knowledge. At that world, he would find his true value as a person.

When Ichiro Shino won 4-billion yen in the lottery, he took refuge in his ancestral home to escape from the hyenas who are sniffing around the money, but then he was suddenly transported to another world....... This is a spin-off of the popular "Lottery" series. The main character is Marie, the head housekeeper of the Istère mansion! Appointed as the commercial manager of the town, she is busy with the development planning, including a new public bathhouse! Familiar characters from the main series, such as Baretta, Lise, and Zirconia, also play an active role.
