Why always me?!?!

This is a story about a hero and what happens after his mission is over... or missions so to say.For he keeps getting summoned over and over to do the same GOD DAMNED THING!TO SLAY THE DEMON LORD!The first 10 summonings were hard and scary... after that it just got annoying and frustrating because he couldn't lead a normal life..After slaying the Demon Lord the God of the current world or some other stupid law or being would always get him back to his old one...But what happens when he gets summoned into a world with a much higher difficulty and not to be on the side of humanity?----------------------------Hi peeps, this is not meant to be take to much seriously. I'm mostly writing this for fun but there will be serious stuff later on.The updates will be random sadly, i will make no promises!There will be mature content as well. Such as swearing(harsh words), gore, torture and later on there will be adult moments as well. So yea.Check it out and leave your thoughts.
