The archangel Sariel is willing to torture people to get what he wants. Soon, Satan and Sariel engage in an aerial battle that destroys half of the city.

Emi takes a trip to Ente Isla. Those left behind in Japan spend a lot of time arguing about whether or not they're worried.

Lucifer is wrecking the neighborhood in a big way and he's brought along some unexpected friends! Meanwhile, Emi, Maou, and Ashiya do the impossible and try to work together!

Maou and company find that a young lady named Suzuno has moved in next door. She is quick to make friends but Emi wonders what her motives are.

An encounter with a stranger has Suzuno reconsidering her position on the Devil. Meanwhile, Yusa begins stalking Sadao and Shiro around town and learns that they are living good, humble lives.

When the lord of demons and his horde waged war against the humans in their realm, a hero vanquished their army. Cornered, the Devil fled through an interdimensional portal to Earth. He vows to one day reign again, but until then... he needs a job!

Something supernatural seems to be going on with Chiho. Meanwhile, it's possible Maou seems to have a difficult time understanding certain concepts.

In the aftermath of the cave-in, Emi sees a side of Maou that doesn't jive with the demonic king. Meanwhile, everyone sees a side of the landlady that nobody could have expected.

Big problems arise when when a new fast-food restaurant opens up. Meanwhile Emi and Suzuno have many miscommunication problems.

Maou tries to handle the loss of business caused by the opening of a new restaurant. Meanwhile Emi and Suzuno need an impartial third party to resolve their dispute.

Emilia the hero finally tracks down the ruler of demons on Earth. Meanwhile, Sadao receives a mysterious text from Chiho warning that more earthquakes are on the way.

It's a busy day at the local amusement park, with crowded restaurants, animals on the loose, scary ghosts, and a much-needed swimwear intervention. Meanwhile, Suzuno feels the presence of a white-winged being watching her.

Ashiya has something he needs to talk to his master about in private. Meanwhile, Emi also has a strange dream where Satan conquers Sasakuza.

Maou and company face their usual budget crisis while Emi and Suzuno attempt to have a conversation next door. It's the same old, same old... except that today, they sense an ominous presence. Before long, a bloodcurdling scream will rend the night.

Back on Ente Isla, the other high priests find out about Olba's betrayal. Meanwhile, Lucifer's moved into the Devil's Castle.

With Ohguro's new and improved look, business is booming! In fact, there are more customers than Maou and his team can handle alone. And at night, there are ominous shadows in the fog...

Emi is freshly struck by all the differences between Ente Isla and Japan. Then Alas Ramus reveals more about herself, causing Emi to reevaluate several things. Meanwhile, Maou is just trying to coexist with Acieth Alla without losing his mind.

Suzuno and Albert's plan hits a snag, but Emi and Ashiya's plans are going oddly well. The big questions of the day are: Can Maou merge with Acieth again? And does he have enough gas left in Powered Dullahan III?

Alas Ramus may be safe, but Maou and his roommates have a few more crises to face. Luckily, they have strong allies on their side.

Alas Ramus seems dead set on the idea that Maou and Emi are her parents. After a few attempts at babysitting by Maou and Ashiya, though, it's clear that Chiho is the only one ready to cope with the realities of parenting. Her boss at MgRonald's isn't thrilled about all of this, but Chiho may have a future in the Devil's army.

Maou, Emi, and Alas Ramus have an eventful day at the amusement park. Meanwhile, their three stalkers do their not-so-great best to blend in.

Emi attends a sleepover at the Devil's Castle. But in the morning, the fight for Alas Ramus and the sacred sword begins. Will Maou and Emi win? Will Gabriel take what's precious? Will there be a magical girl transformation sequence?!

The Sasazuka MgRonald's remodeling is complete. New toilets! Better coffee machines! Maou and Ashiya's worries would be over, if it weren't for the girls' suspicious new habit.

The battle with Gabriel and Raguel is over, but the transition back into daily life isn't all smooth sailing.

Maou has been thinking about dreams ever since his conversation with Kisaki, and he knows exactly what to do next. Of course, whether he can get the necessary parties' buy-in on his dream is another matter...
