Rhett never expected becoming king until he slayed an ice dragon out of self defense and fulfils an ancient dragon slayers prophecy which makes them to crown him as their king.
Transported to a gloomy and medieval like world, he is  faced with leading the dragon slayers, the weakest of slayers among other slayers - demon slayers, gargoyle slayers, ghost slayers and shadow slayers.
But ruling isn't so glamorous as he had anticipated and he is instead a warrior, with a system like ability which he must level up by slaying Dragons.
And to his disadvantage, the world he is his controlled by SLAYERIOUS, an unknown and unseen entity. But that won't stop Rhett, he intends on dominating his world and even daring to slay the strongest dragon still alive, ruieen.
And who knows, he might just defeat SLAYERIOUS if he tries harder.
The only bad part Is that slaying the ice dragon is the first of a prophecy he will have to fulfill, as there are many more prophecies, ones that he must live up to.

I slayed an Ice dragon and now I'm King of the dragon slayers

Rhett gritted his teeth so hard it felt like it would break into pieces. The dragon flew over him, the rider of the dragon with the quite gigantic sword waving it in a whooosh!, aimed at him.

Rhett muffled his shout and quickly lunged sideways, to his left and the sword aimed at his head, bruised the ground and made a big line mark on it.

Rhett stood up and braced himself for the dragon. He didn't care the consequences, he was going to slay it. He breathed heavily as he watched the dragon roll round, coming at him now.

Rhett knelt, and when I mean knelt I mean he knelt with motion, taking himself to slid on his knees forward. Like some footballer celebrating a goal, instead, his was in attack.
