Taken from Baka-updates: Yuri Shibuya was living a pretty normal life. That changed the day he was dunked into a toilet after an attempt to save a classmate from a gang of bullies. Instead of just getting a good soaking, he's pulled in. The next thing he knows, he's in a world that vaguely resembles medieval Europe. If that's not odd enough, he's told that he is to be the next Maoh, just because he has black hair and black eyes. The Maoh is the King of the Mazoku, who are coexisting not-so-peacefully with the humans in this world. Much to his subject's dismay, he's totally different from the rulers they're accustomed to.

Now, Yuri has to deal with trying to become a good Maoh, while at the same time attempting to adapt to this land's customs and culture, all in a world where the tension between the humans and Mazoku is reaching its peak.
