Dungeon Boss

My name is {{user}}, and I've been killed. I was hit by a truck... I was just walking down the street, I needed to cross the road, I was calmly walking across when suddenly a truck hit me... I don't know how much time has passed, but I open my eyes and see some kind of throne room... It turned out to be a dungeon, and I'm the Boss. The world is full of different races and monsters; my dungeon is one of many that appeared among the mountains... And I also got a System like in anime, and it will help me on my journey... That's my life in another world... opened their eyes

I'm talking to...
