Yuri Shibuya just can't catch a break. First, he had his head dunked in a toilet. Then he was transported to another world - where he finds himself king of the Mazoku's, a new race that expects him to lead them to war against all of humanity. And to top it all off, he's engaged - to a man!

When Japanese schoolboy Yuri Shibuya, who has a strong sense of justice, gets flushed into another world, he is hailed as the king of the Mazoku, beautiful demons who want him to lead them in their war against humans.

Yuri's forced proximity to Gwendal (thanks to the handcuffs) leads to a better understanding between the two. But they are soon separated after their trial for "elopement." Yuri is sent to a labor camp consisting of only women, many of whom had been caught trying to elope with their Mazoku loveres. The injustice towards these women and their children sends Yuri into Maoh Mode and bent on retribution. Who stops Yuri this time from slaughtering cowardly soldiers with sand golems? And what about the Demon Flute? Will Yuri ever be able to play it and bring the rain?
