Synopsis

When my curiosity got the better of me in the afterlife, I ended up reincarnating with several things I wasn't supposed to have, like my memories. But I got a second chance at life, and I wasn't going to waste it. Making a nice home in a dungeon, adopting an abandoned girl as my little sister, for someone who died alone, poor, and full of stress, I had everything I wanted and all the stuff I hated were gone.
But while my back was turned, immigrants and refuges?! Land management and negotiations?! Why are you making a country in my backyard?! And everyone wants me to be the leader?! And while I desperately tried to get peace and happiness to my new life, now someone wants my admin powers?!
