In the End of the World, I Have a System and I Am Proud of It

How come monsters suddenly appear on this clean earth? ! "Help! Help." That's right. Unfortunately, I didn't escape and became a monster. Suddenly, a voice woke me up, and there was sand all around me. "Why am I still alive!" "Hahahahaha..." The girl wearing bikini* next to me looked like a fool. "Is this person sick?" Suddenly there was a stinging pain in my head. "Hello, I am your system." I want to be a king! I want beautiful women! The end of the world is my home!
