Chaos Demon King

I was just a senior high school student who was waiting to die, wandering numbly between classrooms and dormitories every day. I never believed in any monsters or monsters in the world. I also long for a fairy to suddenly fall from the sky one day and be my wife. I have been struggling with this... Until the day of my eighteenth birthday... I was drunk for the first time in my life. When I woke up, I found an inexplicable bracelet on my wrist. So, my world was completely turned upside down. I met a girl who stole my eggs and ate them. The girl had a fox tail. I met a man who stole my girlfriend. The handsome man called himself a snake demon. ···· Finally one day, that bracelet told me: You are the Demon King! Fairies seem to be nothing to me anymore...
