Isekai Maou to Shoukan Shoujo no Dorei Majutsu

In regards to the MMORPG Cross Reverie, Sakamoto Takuma boasted an overwhelming strength that was enough for him to be called the Demon King by the other players. One day, he gets summoned to another world with his appearance in the game. There, there are two people that insist "I am the real summon master." Takuma gets slave-turning magic used for summoned beasts cast on him by the girls―

However, the peculiar ability "Magic Reflection" is invoked! The ones that were turned to slaves were the girls!

Takuma was bewildered. He's the strongest magician but, he doesn't have any social skills. Panicking, the first words that came out were the ones that he used inside the game role-playing the Demon King?! "I'm amazing you say? Of course I am. I am Diablo... The one feared as the Demon King!"

This is the story the Demon King (acting) that would soon inspire the world and his other world adventure that he plunges through with his absolute strength, raise the curtain! ​

 

@iNoto you might enjoy this one. Its another Isekai, but the main character is kind of like Ainz, just a socially awkward guy who is RP'ing his OP badass avatar. Its actually pretty well animated too. I doubt its going to be anything special, but its been pretty enjoyable so far imo.

 

@Mahesvara I read the manga even before it got an anime. It's an enjoyable story so far

You might want to check out slime. It's an isekai but this one is pretty good.

 

My only real gripe with this anime is that the two female leads haven't gotten any chance to shine in combat and it just seems like Diablo is doing all the work, i hope that changes.

Awesome will do.
