Summoned: I Really Didn't Want to Rule the World

All I wanted was a quiet life with my summoned creatures—so why did everything go wrong?! My first summon? A psycho who cut off my hand! I'm your master, you lunatic! The second? An obsessive builder who'd rather construct mansions than fight—buddy, I'm broke! The third seemed promising: a legendary fallen general with actual military experience. Finally, someone normal! Wrong. Dead wrong. Now he's demanding I conquer the entire world. How did my peaceful summoner life turn into a world domination campaign?!
