I won 4 billion yen in the lottery, so I'm moving to another world.

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.
