A character is thrown into a new world with a number of cheats. Pretty cliché right? The person in question doesn't think so. This is the story of a man who made a 'Deal with the Devil'.
A guy gains the Gamer System and gets thrown into a multiverse of his own. Now he must balance becoming stronger, getting the girls and surviving this mess all the while entertaining his seniors. Harem, lemons in the future, Gamer MC.
