The Devil Is a Part-Timer!(はたらく魔王さま!,Hataraku Maō-sama?, lit. Working Demon King! or Demon Lord at Work!) is a Japanese light novel series written by Satoshi Wagahara, with illustrations by Oniku (written as 029). ASCII Media Works has published ten volumes since February 2011. The story is about a demon king named Satan seeking to conquer the world of Ente Isla but, when confronted by the Hero Emilia Justina, is forced to retreat through a portal that transports him to modern day Tokyo, Japan. To survive and find a way to return to Ente Isla, Satan gains part-time employment at a fast food restaurant. There have been two manga adaptations published by ASCII Media Works in Dengeki Daioh and Dengeki Maoh. A 13-episode anime adaptation produced by White Fox and directed by Naoto Hosoda aired between April and June 2013.
The Demon Lord and one of his generals, Alciel, escape Ente Isla through a portal to modern Tokyo, Japan after being confronted by the Hero Emilia Justina and her companions. However, due to the lack of magic in the modern contemporary world, both the Demon Lord and Alciel change into forms representing what they would look like if they were human. In order to survive, the Demon Lord takes a part-time job in a fast food restaurant named MgRonald while Alciel serves as his houseman. One day, the Demon Lord, who now goes by Sadao Maō, meets a girl who is actually the Hero Emilia, who now goes by 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.
Sadao Maō (真奥 貞夫,Maō Sadao?) / Satan Jacob (サタン・ジャコブ,Satan Jakobu?)
Sadao is the Devil King 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 and works part-time at a MgRonald franchise, eventually being promoted to a full-time position. He and other demons can turn to their original form 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 like repairing the city which always makes the characters confused due to his position as Devil King.
The Hero who defeated the Devil King. After forcing the Devil King to retreat from Ente Isla, she follows him to modern day Japan to ensure that he is destroyed. However, just like the Devil King, she loses most of her magical powers upon her arrival and is forced to assume a Japanese name and find employment as a call center agent. Her father was human and her mother was an archangel. However, during her childhood, Sadao's commander sent out demons to attack her village which ended up killing her father, which is also the reason why she wants to kill the Devil King.
Chiho is a high school student who is Sadao's friend and fellow employee at MgRonald. She has a crush on Sadao. 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.
One of Sadao's Generals who was also transported to the modern day Japan with him. Extremely loyal to Sadao, he takes care of the domestic duties at home and researches ways to regain their magical powers. Anytime he fails to do his loyal duties, he would often break down or be extremely disappointed in himself for not helping his master. He is also rather frugal in spending habits, often resorting to eating up the udon they had for a long time (which, unfortunately, resulted in him having a really bad stomachache and diarrhea.)
Lucifer is a fallen angel and one of the Devil King's generals. After the Devil King was transported to human world, he and Olba became allies in order to defeat the Devil King so he can return to heaven. After being defeated by the Devil King however, he moves in at the same place as Sadao and Shirō. He's 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 his irritation, he is usually referred to as a hikikomori or NEET, even among company.
Suzuno Kamazuki (鎌月 鈴乃,Kamazuki Suzuno?) / Crestia Bell (クレスティア・ベル,Kuresutia Beru?)
Sadao's next door neighbor. She is always wearing a kimono. Suzuno is the grand inquisitor of the church that came to kill Sadao like Emi. 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 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 went back to the good side by helping Chiho evacuate the area as Satan and Sariel fought. She wields a giant mallet which can be retracted into her flower-shaped hairpin.
Rogue Archbishop of the Church of Ente Isla. He betrayed Emilia and temporarily joined forces with Lucifer to kill Emilia and Satan. Following the failed plans to kill Emi and Sadao, he had gone into hiding. He had been working with the corrupt Church of Ente Isla to kill any and all of their enemies, especially the rebelling 'heretics' such as those of the Allied Knight Order and anyone affiliated with them. He was Crestia's superior and would frequently give her assignments involving the brutal slaughter of the aforementioned groups of people. Following his loss against Satan in Sasakuza, he had somehow found himself in a hospital in the human world, where he regained consciousness after some time. Following this, he tries 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 restrained, this time by Lucifer.
An Archangel used by the Church of Ente Isla as part of their Execution Inquisition along with Crestia Bell. He had first attacked Emilia in disguise at a convenience store. In order to learn a bit about Satan and Emilia in the human world, he forges the identity of "Mitsuki Sarue" claiming to be the manager of the newly opened Sentucky Fried Chicken franchise in Hatagaya. He eventually teams up with Crestia in order to kill Emilia and Satan. His weapon is a large scythe and possesses a power called the 'Wicked Light of the Fallen' a magic capable of nullifying all sacred powers, as shown when he battles Emilia. During his conflict with Emilia, he demands that she return the sword 'Better Half' to Heaven. This prompts him to take Emilia and Chiho hostage but he is ultimately defeated by Satan. He draws his magic from the Moon, with his power increasing in inverse proportion to his distance from it. He also has a perverted tendency, after he expresses a desire to strip Chiho down in his experiments to learn how she has been influenced by Satan's magic.
She is the owner of the "Villa Rosa Sasadzuka" apartment building where Sadao Maō and Suzuno Kamazuki live. She is very obese and seems to know more than a Japanese person should about the visitors from Ente Isla.
