REINCARNATION of an Average Salary-man as a DEMON KING?

Upon entering the dungeon Ran saw an enormous door.It was over three story tall. Ran opened the door and walked in. With a loud thud sound Ran was slammed into the corner as the massive beast struck his cudgel into the ground near him. He couldn't do anything except get away from the massive beast. He slowly Limped away as the beast was getting his cudgel up. He noticed his hp was getting low every few seconds. He noticed there was a blinking blood symbol next to his hit points. He realised it's bleeding effect and he was not surprised as blood was flowing out of various parts of his body With a tired and disappointing chuckle he said "If I had known I'd die again so soon, I would have chosen one of the other two choices but then again I am known for making bad choices in previous life aswell". Ran yelled "Tarot reader" and a window popped up displaying 'REVERSED WHEEL OF FORTUNE CARD' and the message 'the probability of him getting out of this situation is 80% unlikely' He knew the situation was bad but he didn't know it was this bad. Because he wanted to go down in a cool way. He spat the blood out of his mouth and yelled "Come on beast!". But what can you expect of an average salary man he had never faced two story tall beast in his entire life so when he saw the massive beast charge towards him his legs lost all of their strength. As he was about to fall unconscious a window popped up 'conditions are met now you can use the ring of randomness' would you like to use it now?'. He didn't have any other options left he yelled out "YES!" and a small cyclone formed around him. It filled up the room with the dust that had been resting on the floor. The beast stopped charging as the cyclone emerged and had its guard up "now now don't be so surprised." ,Ran said with a smirk as the dust settled and revealed ran he was not too far from the beast. As he emerged from the dust filled cyclone an ice crown could be seen floating on his head, His leather gloves froze and a glowing symbol formed on his gloves. His eyes were shining white in the dark dust filled room and with a grin again he said "now the playing field is even".
