The Demon King Satan is only one step away from conquering the world when he loses to the Hero Emilia Justina. Thus, he has no choice but to escape to another world: modern-day Tokyo. However, as skills related to conquering the world are useless in his new situation, he must work a part-time job to pay for his living expenses. The Hero pursued him, but in this peaceful world that doesn't need saving, she has to work at a customer support call center. Under the names Maou Sadao and Yusa Emi, they meet again in a situation where they no longer have a reason to fight.
Chiho has a strange dream where Satan leaves Earth and returns to Ente Isla, leaving her behind much to her agony. While recalling the dream to Sadao the next day he confirms that he doesn't have enough magic to return since he used it all repairing the city from his and Sariel's battle the previous day. At the same time, they discover Sariel in MgRonald's freezer since Sadao's magical bamboo had redirected his portal. Sariel immediately falls head over heels for Mayumi much to her disgust. Meanwhile, Emi also has a strange dream where Satan conquers Sasakuza. As she goes to visit Sadao and co. Shirō asks Sadao for some time off which makes her suspicious, causing her to enlist Emeralda to see what they might be up too. Later, Emi notices numerous boxes being delivered to Sadao's apartment and grows even more suspicious. At work, Sadao suddenly asks Mayumi for a shift change which causes Chiho to fear that he might return to Ente Isla, but Sadao apologetically keeps their motives hidden from her. Chiho and Emi decide to follow Satan the next day to find out what they have been up to and discover that he along with Shirō had taken extra jobs to pay for Hanzo's GPS trackers which had saved them from Sariel. As Emi questions Sadao on the boxes, they return to the Villa Rosa to discover that Hanzo had been caught in a purchasing scam whereby he was tricked into buying useless items. Sadao and Emi head over to the retailer to claim a refund, and discover that Shirō had been working there, along with a threatening manager who refuses a refund due to a contract Hanzo had signed.

Shirō steps out of his hospital room for a bit and notices an unconscious police officer. While investigating, he is violently punched into submission by the newly awakened Olba, who learns of Sadao's residence from Shirō's insurance card. Atop City Hall, Sariel sadistically begins torturing Emilia in order to obtain the Better Half, although it refuses to manifest in his presence. Meanwhile, Satan arrives and destroys Sariel's barrier using his remaining magic. At that moment, Crestia attacks him with a magical mallet and is surprised to learn that Satan and his fellow demons had known about her since she first moved into the Villa Rosa. Not having any magic, Satan takes a beating from Crestia but gets up nonetheless to rescue Chiho from Sariel, leaving Crestia to realize that unlike Satan, she had abandoned her friends. At the same time, Olba visits Lucifer and seeks to reestablish their contract. As Sariel begins to reveal a perverted nature, Emilia claims that Satan will show up to save Chiho because of his natural instinct to protect his fellow coworkers, which is mocked by Sariel. Much to Chiho and Emilia's relief Satan does arrive but is easily overwhelmed by Sariel due to his lack of magic. Elsewhere, Olba replenishes his magic with Emilia's drink and casts a spell which enlarges the Moon, which increases Sariel's magic while subsequently throwing the city into mass panic. The panic grants Satan an enormous magical boost but Sariel remains confident in his power, even as Crestia decides to side with Satan. Elsewhere, Lucifer knocks Olba out, cancelling the Moon spell, after deceiving him into throwing the city into panic for Satan's advantage. Finally Satan and Sariel engage in an epic aerial battle which destroys half of the city and ultimately ends with Sariel's defeat to Satan's demon sword.

Later, the police track down Sadao from his bicycle left at the scene and Emi is forced to vouch for his identity while afterwards warning him about their common enemy. Later, Sadao meets Chiho for their date which, unbeknownst to them are followed by a cautious Shirō and a suspicious Emi, the latter of whom drags Shirō into the cafe to eavesdrop on Sadao. During the date, Chiho explains to Sadao that she had been hearing a strange language recently (the language of Ente Isle unknown to her). She further explains that the speakers were trying to contact someone and made references to a large earthquake soon to occur. Sadao realizes that the phenomena was a magical communication system called "Idea Link" and that the earthquakes were most likely caused by a Sonar Spell trying to detect him and Emi. At this time a shocked Sadao notices Emi walk into the cafe and before Chiho can to confess to him, she is interrupted by Emi. Chiho misunderstands Emi's reasoning for her interruption and they get into a loud argument, just as a large earthquake suddenly strikes. When Chiho briefly awakens, surrounded by devastation, she reconciles with Emi who again warns her about Sadao before knocking her out with a Sleep Spell. Emi then calls out to Satan who appears from some debris in his demonic form.

Suzuno further asks that Emi return to Ente Isla to confront the Church about the cover-up regarding Olba's traitorous actions, after defeating Satan. Although Emi remains hesitant in trusting Suzuno since the actions of her superior put the lives of everyone in the underground mall in danger just to kill her and Sadao. Before she leaves, Emi advises Suzuno to be leery of Sadao and co. finding out her true agenda.
