Need Help Finding a Manga

[pillarmen123]

Hey guys, anyone knows the title of this manga?

The plot was something like this guy who worked in the demon king's castle, got fired by an incompetent higher up, finds himself in a human village and ends up marrying this girl with a huge rack that happens to be very strong. last part I remembered was something like fighting for mythril mines rights

Thanks in advance!
