Wow. What an anime. I don't know about the rest of the reviews, and I'm not really a good reviewer, but WOW. That is all I can say about it. It's absolutely hilarious and has the best first and last episodes I've seen yet (IMO).
Story - 9
So lets see, it's about Sai Akuto, a young man who wants to change the world and to do so, become a High Priest. He befriends a "reckless" girl and they make off to the Academy. All of a sudden, the machine that determines your future tell him that he is... You guessed it, a Demon King. Then hilarity ensues.
Art - 8
The art was average, but the character designs made use of that, and the beasts are all well portrayed.
Sound - 10
I loved the OP and ED music, as they were original and catchy. The in-battle music was epic as well.
Character - 10
So lets see. We have:
-Tsundere
-Lilidan (Android)
-Intelligent MC
-Thick-As-Brick MC fanboy
-Another Tsundere (I guess)
-Magically-Useless Readhead
They were all made well and developed highly in the story, leaving no characters being thought about for what could have happened
Enjoyment - 10
This anime appealed to me and all that I would have wanted in an anime, and it's just very cool and amazing. I mean, after the first episode I downloaded the entire series! I recommend this to anyone who likes action, Demons, powerful MC in a harem, epic concept, and if you don't mind a bit of Ecchi.
