Plot 
The Demon Lord Satan seeks to conquer the world of Ente Isla by annexing its four continents with the help of his demon generals Alciel, Lucifer, Malacoda, and Adramelech. After being confronted by the hero Emilia and her companions, after they had killed Malacoda and Adramelech, Satan and Alciel escape the world of Ente Isla through a gate to modern Tokyo, Japan. However, due to the lack of magic in the modern contemporary world, both Satan and Alciel change into forms representing what they would look like if they were human. In order to survive, Satan takes a part-time job in a fast food restaurant named MgRonald's, while Alciel serves as his houseman. One day, Satan, who now goes by Sadao Maou, meets a girl who is actually Emilia in the form of Emi Yusa. The story then unfolds and explores the personalities of each of the characters and their moral values. More characters show up from Ente Isla and they too face the new world dilemmas, often comically.

Characters

Main characters 
 

Satan Jacob is the Demon Lord from Ente Isla. Due to the actions of the Hero Emilia Justina and her companions, he was transported to modern day Japan with Ashiya and changed into human form. To survive in Japan, he adopts a Japanese name similar to his original name, Sadao Maou, and works part-time at a MgRonald's franchise, eventually being promoted to a full-time position as the Assistant Shift Manager. He and other demons can turn into their original forms when people around them are filled with despair. However, when he changes his form to his devil form, he uses his powers for good deeds such as repairing the city, which always makes the characters confused due to his position as the Devil King. Throughout the series his current personality is often called into question, though it is later shown that he had always been like that, and was never once this "Evil Overlord" that the people of Ente Isla had grown to fear and hate; in actuality he did the "evil" things he did to help his people, the other demons. As he told Emilia when he saved Chiho, he just wants to protect the people under his care and around him. When he was younger, he was saved and taught by Emi's mother, Lailah. She also gave him a fragment of Sephiroth that would later become his and Emi's appointed daughter Alas Ramus. He would eventually fuse with Alas Ramus' "younger sister" Acieth Alla (who is another fragment of "Yesod") in order to save Emi and Ashiya after they were kidnapped by Olba and the Angels to fight in Ente Isla.
 

Emilia is the hero with thigh-length magenta hair who fended off Satan. After forcing Satan to retreat from Ente Isla, Emilia Justina follows him to modern day Japan to ensure that he is destroyed. Like Maou, she loses most of her magical powers upon her arrival and is forced to assume a Japanese name, Emi Yusa, and find employment as a call center agent. Her father was human and her mother was an archangel. However, during her childhood, Lucifer, one of Maou's generals, led an army of demons to attack her village, resulting in the death of her father. This is revealed to be the reason she wants to kill Maou. However, it was later revealed that her father was alive. Emi is later fired from her job at the call center and gets a new job at MgRonald's where she works with Maou and Chiho. Maou also appoints her as a Demon General of the Demon Army despite her protests. She later develops feelings for Maou, though she struggles to reconcile her feelings due to their previous history along with knowing that Chiho is also in love with him.

Chiho is a high school student who is Sadao's friend and fellow employee at MgRonald. She has feelings for Sadao. Chiho is an average teenage girl of short stature who sports a highly curvaceous figure, a fact which is noted by several people and envied by other girls, especially Emi. She can hear and understand the language of Ente Isla due to accidentally being targeted with a communication spell intended for Emi, because the spell was set to target those who were thinking about Sadao constantly. She later learns how to use the magic spell Idea Link to allow her to alert the others if she is ever in danger. She is also able to use magic to enhance her archery skills. Maou appoints her as a Demon General of the Demon Army much to her happiness, and becomes well respected within the demon community as well. In order to gain the Spear of Adramelechinus (needed to power the Demon's Castle to reach the Angels' stronghold on the moon), she gets involved with the politics in Ente Isla. The light novel ends with her being together with Maou.
 

Ashiya is one of Satan's Generals, who was also transported to modern day Japan with him. Extremely loyal to Satan, Alciel takes care of the domestic duties at home and researches ways to regain their magical powers. On Earth, Alciel assumes the form of Shirō Ashiya who operates as Sadao's housekeeper. Anytime he fails in his duties, he is extremely disappointed in himself for not doing a better job at helping his master, even suffering emotional breakdowns. He is also extremely frugal in his spending habits, once resorting to eating a large amount of leftover udon that was about to expire (which resulted in a severely upset stomach). He has alluded to reciprocate Rika's love, though is currently unwilling to pursue a relationship with her due to believing that she fell in love with his human guise and not his demonic "true self".
 

Lucifer is a fallen angel and one of Satan's generals. After Satan was transported to the human world, Lucifer and Olba struck a deal in order to defeat Satan, with Olba promising to return Lucifer to heaven. After they are defeated by Satan, however, Lucifer moves into the apartment belonging to Sadao and Shirō. He is good with technology and loves playing video games. As a result of committing a series of robberies with Olba before being defeated by Sadao, he must remain in seclusion to avoid the police. To his irritation, he is usually referred to as a hikikomori or NEET, even when guests are present. His mother is the current leader of the angels, Ignora, and his father was the ancient demon lord, Sataniel.
 

Sadao's next door neighbor. She is always wearing a kimono. Suzuno is the grand inquisitor of the Church in Ente Isla that, like Emi, came to kill Sadao. Unlike Emi, she apparently has trouble adjusting to the modern life of Japan and is easily found having trouble, especially with Japan's technology. She has coped with Japan, but with the old style of Japan. She briefly teamed up with Sariel to eliminate both Sadao and Emi after Sariel reminded her of her duties as grand inquisitor, but after seeing Sadao concerned for Chiho and realizing that she values her friendship with Emi and Chiho, she ultimately turns against Sariel by helping Chiho evacuate the area while Satan and Sariel battle one another. She wields a giant mallet, which can be retracted into her flower-shaped hairpin. Maou appoints her as a Demon General of the Demon Army despite her protests. She eventually develops feelings for Maou, though struggles to accept those feelings due to their past history. She is eventually promoted to the post of Archbishop of the Church in Ente Isla.

He was Crestia's superior and would frequently give her assignments involving the brutal slaughter of the Church's enemies. Following his loss to Satan in Sasakuza, he is placed under guard in a hospital, where he regains consciousness after some time. After he escapes, he attempts to reestablish his contract with Lucifer and proceeds to aid Sariel in his battle against Satan by casting a spell to increase his power. It turns out that he had been tricked by Lucifer into creating a panic with the Moon spell, which causes Satan to regain his magic and defeat Sariel. Following Sariel's defeat, he is once again defeated and restrained, this time by Lucifer.

He defeats and tortures Emilia while taking Chiho hostage, but he is ultimately defeated by Satan Jacob. He draws his magic from the Moon, with his power increasing the closer he is to it. He also has perverted tendencies, shown when he expresses a desire to strip Chiho down in his experiments to learn how she has been influenced by Satan's magic. After his defeat he develops an immediate infatuation with the manager of MgRonalds, much to Emilia's annoyance and Kisaki's dismay.
