Kazuyoshi won a massive lottery prize of 4 billion yen from a lottery ticket he bought on a whim. To escape from hyenas who caught the scent of money from somewhere, Kazuyoshi takes refuge in an old mansion that has been passed down through his family for generations. While investigating the inside of the mansion where he's hiding, Kazuyoshi discovers that a certain room is a space that can exchange goods with another world. In this other world, which appears to have considerably low levels of culture and technology, the protagonist brings items and technology from time to time, attempting to find his value in that world. The main story is complete. Epilogue chapters are posted irregularly. ※It has been published as a book under the new label Monster Bunko by Futabasha Publishers. The book version is also complete. All 18 volumes of the bunko edition are now on sale. A comic adaptation is being serialized on Comic Walker. A spinoff manga "Marie's Hysteria Commercial Development Record" with all 6 volumes on sale at Gaugau Monster.
