Jack, I suggest you to look for a manga/light novel of Infinite Dendrogram. The basic thing about it is... well...
Imagine SAO, Log Horizon, and Overlord all in one clusterfuck of a mess, except that the mess is an organized mess. There are cliches here and there but the "Dense Protagonist" (Infinite Stratos) + "OP AF" (SAO) + "Monotony Moments" (Reincarnated into a Slime) goes out of the equation.
