The devil Eclair has come to the human world with one goal in mind: to find a wicked soul worthy of serving her! But when her search leads her to a sleepy rural police box, she meets Kuwabara Daichi —a straight-laced cop whose fearsome scowl screams villain. Convinced she’s found her perfect underling, Eclair turns on the charm to seduce him down to the underworld. Too bad this overworked officer would rather send her back there—alone! Heaven help him… because this devil isn’t giving up that easily!
Even if she’s a devil with villainous intentions, Eclair is beginning to enjoy her life on the police force–but then the delinquent girl Maya appears before her! Maya makes a sudden proclamation of war against Eclair, who has declared herself master of all the Earth. It’s the beautiful delinquent vs. the devilish temptress policewoman…and the loser becomes the winner’s servant! But where the heck are the two of them going to hold their battle? At the end of the day, this is still a rom-com, right?!
