At the start of the story he won a lottery. The money is in cash.
Still doesn’t erase the fact that his money isn’t running out. I get it it’s manga and fantasy but still doesn’t mean he has infinite money
Point taken. However, 40 billion yen is still a lot of money! He's pretty much only spending it on the other world.
40 billion yen is a little less than 400 million usd. Even with every thing he's buying, since the vast majority of it comes from the convenience store and most are farming materials, it'd be hard to blow through all that money
It is getting boring for me... (︶︿︶) and what’s with his money? Does his card not run out of money seems like his card has magical not-running-out-of-money
