Fan Art of an Anime called How to not summon a Demon Lord, the main character as you can see here is called Diablo. 

If you have no idea what Anime this is, let me brief you. The main character goes by Diablo in his favorite MMORPG, yes he is a shut-in neet however all that changes when he fines himself in another world, summoned by a busty lady Elf Shera and a petite cat women Rem. Some how he has been sucked into the game world but it just seems too good to be real until he notices he is wearing all the gear from the world on his person. Diablo was summoned to defeat the Demon King however with his extremely bad social skills he has a lot to learn. He is the only one that can defeat the impending doom and kill the demon king. 

Sorry for the bad explanation of the Anime, it's what I could come up with really, haha anyway I decided to draw Diablo because I really never drawn a Male character and I wanted to draw a character I liked so clicking through some of the anime I've watched I came across How not to summon a Demon Lord, I re-watched the series and here we are. 

I hope you like my Fan art of Diablo. 

Let me know what you think.
