Speak of the devil, and he'll fry you a burger! Sadao Maou, (aka Satan, the Devil King) has been relegated to flipping burgers at a MgRonald in suburban Tokyo. His greatest challenge so far, though, comes when a Sentucky Fried Chicken opens up across the street. Maou once led the forces of darkness, but can he triumph over the forces of chicken? And the new girl next door seems awfully polite and proper, almost as if she were hiding something...
Do you want fries with your hellfire? Being soundly thrashed by the hero Emilia, the Devil King and his general beat a hasty retreat to a parallel universe...only to land smack in the middle of bustling, modern-day Tokyo! Lacking the magic necessary to return home, the two are forced to assume human identities and live average human lives until they can find a better solution. And to make ends meet, Satan finds gainful employment at a nearby fast food joint! With his devilish mind set on working his way up the management food chain, what will become of his thirst for conquest?!
Old Friends, new enemies! In the Sasazuka neighborhood of the Shibuya district of Tokyo, newly minted part-time burger-flipper and former Devil King Satan (now known as Sadao Maou) clashes with Lucifer, a fallen angel who used to serve him! But how will the onetime king deal with his rival now that his magic power's run dry? Now that the devil is one of us, he's going to have to get creative!
Chiho has collapsed, and Maou and company have figured out that it must be the work of an Angel. The only thing left to figure out is whether they're holed up in Tokyo Tower or the Sky Tree. When the group finally finds whoever's responsible for hurting their friend, the ultimate Maou/Alciel combo is going to paint the town red!
This complication wears a kimono! The arrival of Suzuno Kamazuki has made everybody's life more complicated! After some misunderstandings regarding Suzuno's intentions toward Maou are cleared up, Emi asks for her help to...defeat the Devil King?! Meanwhile, a shadowy assailant continues to stalk Emi, but what does he--or she--want?
THE DEVIL FINDS WORK FOR IDLE HANDS! MgRonald is closed for renovations, which means Maou is temporarily out of a job! His hunt for employment takes him all the way to Chiho's family farm in Nagano, where he'll get a taste of the agricultural life. Can he and the others survive their time in the sticks, or are they simply too spoiled by the city? And if Maou does learn the value of hard work, what of all the farms he trampled during his time as the Devil King...?
The Devil's Castle (Maou's tiny apartment) has a new resident, and she's still in diapers! With the appearance of the mysterious child Alas Ramus, Maou's household is plunged into chaos. With the Devil as the daddy, and the Hero mommy, playing house just got serious!
The Devil goes digital! Repairs to Devil's Castle, Maou's one-bedroom apartment in Japan, are complete--and now it's outfitted with an all-new HD socket! The Devil King's never owned a TV before, so once he's armed himself with all the knowledge he needs, he's off to the electronics outlet. With Lucifer the only one home, what will happen when a certain angel makes an unexpected visit...?
Maou (the Devil King) has a suspicion about the mysterious child Alas Ramus, a wee lass who he and Emi (the Hero) have wound up parenting. During a supremely awkward "family outing" to the amusement park, Emi gets Maou to tell her the truth about their little girl. But when a chorus of angels shows up to settle an old score, Maou's revelation may not matter!
DISTURBANCE SEASIDE! The Devil King is on the beach, but there's no time to relax! People are packed into the eatery, and Maou's crew can barely keep up with the demand. Looks like the girls will have to come to their rescue! Everything's fun on the shore, but with the appearance of Maou's military adviser, is there trouble on the horizon?
