Maou y compañía enfrentan su crisis presupuestaria habitual mientras Emi y Suzuno intentan tener una conversación en la casa de al lado. Es lo mismo de siempre... excepto que hoy sienten una presencia ominosa. En poco tiempo, un grito espeluznante desgarrará la noche.

Alas Ramus parece decidido a pensar que Maou y Emi son sus padres. Sin embargo, después de algunos intentos de Maou y Ashiya de cuidar a los niños, está claro que Chiho es la única lista para hacer frente a las realidades de la paternidad. Su jefe en MgRonald's no está entusiasmado con todo esto, pero Chiho puede tener un futuro en el ejército del Rey Demonio.

Maou, Emi y Alas Ramus tienen un día lleno de acontecimientos en el parque de diversiones. Mientras tanto, sus tres acosadores hacen todo lo posible por pasar desapercibidos.

Emi asiste a una fiesta de pijamas en el Castillo del Diablo. Pero por la mañana comienza la lucha por Alas Ramus y la espada sagrada. ¿Ganarán Maou y Emi? ¿Tomará Gabriel lo que es precioso? ¿Habrá una secuencia mágica de transformación de chicas?

Por desgracia, Ramus puede estar a salvo, pero Maou y sus compañeros de cuarto tienen algunas crisis más que enfrentar. Afortunadamente, tienen fuertes aliados de su lado.

¡Con el aspecto nuevo y mejorado de Ohguro, el negocio está en auge! De hecho, hay más clientes de los que Maou y su equipo pueden manejar solos. Y por la noche, hay sombras ominosas en la niebla...

Emi, Maou, and the gang learn the source of the recent demon invasion, as well as some surprising facts about Choshi City and their boss.

Maou, Ashiya, and Urushihara get a farming job on Chiho's recommendation. Emi seems to have some feelings about it.

Thieves and demons and bears, oh my!

Maou thirsts for a TV, Emi learns some shocking news, and Urushihara schools us all on how to be proper NEETs.

Buying the Devil's TV is more exciting than anyone expected. Unrelatedly, Maou is wiser about human relationships than anyone expected.

The whole gang prepares for their showdown with Raguel. But the fight has a lot of unexpected twists and turns, thanks to meddling from more than one immortal.

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...

Alas Ramus deserves a safe and comfy place to sleep! Emi and Maou go on a futon-shopping quest while Ashiya and Urushihara try to figure out what's going on with Suzuno.

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.

Urushihara and Suzuno rush to Chiho's aid, but Maou lags behind thanks to his lack of magic and his confusing new acquaintances. Meanwhile, Ashiya has the toughest job of all: explaining all this to Rika.

Who's holding Emi hostage? Why are so many humans, demons, and angels after Ashiya? Maou needs to find out all this and more, but first he needs a new source of power to defeat the invading army with.

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.

Maou and Suzuno make their way through Ente Isla's forests. Emi and Ashiya each learn what they've been brought to Efzahan for.

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?

At last, all the players are in place for the final battle in Efzahan. What happens next?
