List of Seven Mortal Sins episodes

Freshly cast out of Heaven, the former angel Lucifer makes a brief stop in a high school church on Earth, where she encounters a girl named Maria Totsuka before continuing her fall to Hell. Once there, she is met and fawned over by Leviathan, an aspiring minor Demon Lord, and challenged to combat by Satan and Belial, two Demon Lords of the Seven Mortal Sins and members of the ruling council of Hell who accuse her of intending an invasion of their territory. Despite gaining the upper hand initially, Lucifer is eventually subdued by Belial and stripped of her angel powers and wings; but with this last link to Heaven gone, Lucifer transforms into a demon lord herself. Along with Leviathan, she returns to Earth and meets Maria again, whom she promptly stabs through the heart.

Instead of killing her, Lucifer removes Maria's heart from her body, turning the hapless girl into her immortal thrall. Lucifer and her entourage move into the presidential suite at the Royal Towers Hotel. As they partake in the luxuries of their new quarters, Leviathan tries her best to gain her new mistress' favor, but grows increasingly jealous when Lucifer pays more attention to Maria instead of her. As a result, when Lucifer makes a short trip to take her mind off her defeat against Belial for a while, Leviathan begins to sexually torment the forlorn girl; but when Maria eventually admits that she has herself sometimes felt envious of her friend Mina because she had not found anyone to love in her life, and states that envy born of love is not a sin, she manages to stir doubts in Leviathan and break the demon's hold on her. After Maria has regained consciousness, Lucifer, by licking her breast, stimulates Maria's special gift of seeing into discerning the current location of one of the Mortal Sins. Upon hearing that one of them is in Miami, Lucifer calls for their immediate departure.

Arriving in Miami, Lucifer, Maria and Leviathan catch Asmodeus, the Demon Lord of Lust, openly seducing the local beach-goers in order to consign their souls to Hell and thereby increase her power base. With all the lust from the crowd bolstering her powers, the protagonists find themselves outmatched in open battle and are forced to retreat. A later attempt at a night club, where Asmodeus performs a pole dance, likewise fails when Leviathan, with her lust for Lucifer, easily falls prey to Asmodeus. However, since Maria has attracted Asmodeus' attention, Lucifer uses her as bait, and the girl's piety and innocence help her in withstanding Asmodeus' seductions long enough for Lucifer to track them down. Asmodeus ensnares Lucifer, but her own power is turned against her when Lucifer points out that lust is something completely natural, thus negating her status as a Mortal Sin and the link of the Garb of Punishment powered by Lust. Lucifer spares Asmodeus' life, who graciously accepts her defeat.

Lucifer and her entourage track Mammon, Demon Lord of Greed, to London, where she runs a potion-selling business. Upon entering the shop, they are caught in a trap. Lucifer takes up Mammon's challenge to a personal duel, is beaten and subjected to sexual torture astride a wooden horse; but even after Leviathan manages to free herself from her cage and rushes to her aid, Lucifer decides to ride out the torment. Meanwhile, Mammon returns to her shop and attempts to seduce Maria, who was left behind by Leviathan, into selling her soul and acting as a nursemaid for her 500,000 children. But Maria resists by pointing out that the children need their mother, not a substitute; and with her pride finally overcoming her agony, Lucifer breaks free and defeats Mammon, destroying her shop and freeing all the prisoners she has ensnared, as well as breaking another link of her Garb of Punishment.

Recap of episodes 1-4.

Lucifer next confronts and challenges Astaroth, the Demon Lord of Melancholy, who is making a living as an internet rock singer. Compelled by Maria's suggestion, Lucifer establishes herself as a singing idol in order to out-achieve Astaroth, which develops into a hard popularity contest once Astaroth receives Belial's and Belphegor's backing. Finally, Astaroth ascends into the professional music world, but as her popularity grows, so does her insecurity. At the final showdown during her first live performance, Astaroth ends up sharing the stage with Lucifer and losing, but although she remains loyal to Belial, the parting of the adversaries ends up quite amicably. And as a reward for her efforts and dedication, Lucifer grants Maria the boon of addressing her more informally.

While she attempts to contemplate a strategy on how to confront her next adversary, Belphegor, Lucifer is drawn into a virtual world created by the Demon Lord of Sloth inside the Internet, where Belphegor challenges her in a multiplayer online game for world conquest. When Lucifer proves too tough for her and her followers to handle, Belphegor traps Maria inside her virtual game world as well and tricks her into becoming her lingerie-armored champion. After some laborious training and receiving a special set of armor, Maria - who has in the meantime realized the truth - manages to defeat Lucifer, but refuses to finish her off. This allows Lucifer to recover and use her magic to destroy the fabric of Belphegor's virtual world, and with her power diminished by the desertion of her followers as they unlink themselves from the game to pursue matters in the real world, Belphegor is plunged into defeat.

During an erotic dinner party hosted by Beelzebub, Lucifer pops up and challenges the Demon Lord of Gluttony to an eating contest. In the midst of it, however, Lucifer ends up being hospitalized with a stomach flu, and sees herself confronted by the worry and care of her companions Maria and Leviathan (something she is not used to at all), and Belial posing as her treating physician. To her surprise, Lucifer eventually finds herself sharing a room with Beelzebub, who is a regular patient in the hospital for gastric dilation. As the two begin to become friends, Beelzebub admits that she likes to eat not because eating is supposed to be a sin, but because it is supposed to bring joy and happiness to the people. After being discharged, they share a friendly meal together, and Beelzebub willingly forgoes her status as a Mortal Sin. However, just then Maria is kidnapped by Belial, who has discovered the emotional bond Lucifer shares with the girl.

Belial seeks out Satan, the Demon Lord of Wrath, and tells her that Lucifer has managed to subjugate Beelzebub (conveniently neglecting to mention that Beelzebub did so willingly), inciting Satan to seek out the fallen angel and punish her for this supposed transgression. Leviathan engages her in battle to defend Lucifer, but with the city currently gripped by wrath and thus fueling Satan's power, she is easily defeated. Encouraged by Beelzebub and her fondness of Maria, who is now imprisoned in the palace of the Seven Sins, Lucifer faces Satan and her fleet of conscripted Navy warships. When she is pushed to the verge of defeat, Beelzebub brings Leviathan back from unconsciousness, and the tide of battle is quickly turned. After relocating to the surface on the Moon, Satan confidentially unseals her portion of Lucifer's Garb of Punishment, returning a portion of her powers, and faces off against her opponent in single combat. Despite the Demon Lord's vast level in power, Lucifer manages to beat Satan, who admits defeat and willingly agrees to open the gates of Hell so that Lucifer can carry the final fight to Belial herself.

For her failure to subdue Lucifer, Belial imprisons and torments Satan, forcing her to guard the gates to Hell against Lucifer's impending intrusion. But prior to her invasion, Lucifer has utilized her new abilities as a demon lord to draw power from the lingering pride in every human's soul, thus gaining entry. As Lucifer and Leviathan make their way down to the lower levels of Hell, Belial attempts to rally the other Mortal Sins, but except for Astaroth they all refuse to follow her any longer. After struggling with a lewd Charon, Lucifer and Leviathan reach the Palace of Minos, where they are met by the other Seven Sins. It is then that Lucifer reveals why she was cast from Heaven: God had issued an order to the Seven Heavenly Virtues to purge both Hell and Earth, even though the corruption of humanity - and thus the existence of Hell - is part of an inevitable course which cannot be broken even by God's power; and Lucifer was banished when she protested against the perpetual repetition of this measure throughout the millennia. It is also revealed that Belial knew about this, and has struck a deal with Michael to have Lucifer delivered to her for eternal damnation in exchange for the release of all souls trapped in Hell and getting exempted from the purge. Astaroth, refusing to believe that Belial would betray them all, attempts to attack but is held off by Leviathan, while Lucifer continues her journey down to Cocytus.

While Lucifer, accompanied by Behemoth, makes her way down the circles of Hell, Belial confronts the rogue Seven Sins and subjects them to punishments befitting their respective natures for defying her. When Lucifer encounters her allies and wishes to aid them, most of them agree that they must ride out their torment as a final purge of their former ties with Belial and as acceptance of their new allegiance with Lucifer. However, by the time Lucifer reaches the palace of the Seven Sins, she is nearly drained of power, leaving her helpless before Belial.

A special clip episode highlighting some of the lewder scenes in the series.

When Lucifer regains consciousness, she finds herself restrained and tortured by Belial, who reveals that she found Lucifer's angel blood in Maria and plans to use it to return to Heaven, as she was once an angel herself but banished by Lucifer in God's name after she had inadvertently caused the humans she meant to gather as God's followers to fall prey to sin. Now, with the deal she has made with Michael and Lucifer's blood in her possession, she intends to usher in a new age in which God's glory shall reach unforeknown heights and she will thus be reinstated as an angel. But with her renouncement of her role as the ruler of the Seven Sins, the tortures she has inflicted upon the others are cancelled out; the five rogue Sins free Lucifer but are imprisoned themselves when Belial wields Lucifer's power she has absorbed against them. Belial then torments Maria into stabbing Lucifer through the heart; but by willingly sacrificing herself, Lucifer manages to swap her heart with Maria's, restoring them both. In the subsequent duel, Belial is easily defeated, but then Michael arrives in Cocytus and enters the Palace of the Seven Sins.

As Belial begins to gather new hope, Michael coldly crushes her by stating that she never intended to honor their contract in the first place, and sets out to destroy Hell. Joined by the infuriated Belial, the Seven Sins take up the fight against the archangel and shatter the power God has granted Michael for the task, enabling Lucifer to engage her on equal grounds on Earth. Michael succeeds in fatally stabbing Lucifer with the Lance of Longinus, but with her love for Lucifer, Maria willingly sacrifices her life to bring her back from the verge of annihilation. Now uniting the powers of Heaven, Hell and Earth within herself in a new trinity, Lucifer defeats Michael but spares her, sending her back to Heaven, and manages to bring Maria back from death. While Belial and Astaroth begin a new life together on Earth, Lucifer and Leviathan take their place as the Lords of Mortal Sins in Hell, in preparation for Lucifer's final onslaught against Heaven to liberate humanity from God's arbitrariness.

This episode explores how hard Belphegor works to be lazy. She orders liquor on the Internet, but loses patience and goes to the store to buy it directly. She fishes for and cooks a cherry snapper, then after eating and drinking, sleeps under the cherry blossom trees. When she wakes up, she orders sake on the Internet.

The bottle lands on the rope hard enough to rip the tape off, making the two scream in pain.

Leviathan buys a pack of bandages, then in the restroom, she painfully replaces the bandage over her groin.

Astaroth visits Belphegor and berates her for her extremely messy room. When she spots an erotic video game, Belphegor suddenly seduces her and they start having sex. This is revealed to just be Astaroth's daydream. Embarrassed, she tries to leave, but bumps into a pile of junk and gets buried under it.

In either a fantasy or virtual world, Mammon seduces an adventurer who finds that touching her breasts increased his strength, so he thanks her with gold. She opens a booth charging people for access to her breasts.

Beelzebub, Belial, Mammon, and Asmodeus relax in the hot spring, but Beelzebub is jealous of the others for their large breasts. The others combine their powers to enhance her bust size, cheering her up, but her new breasts turn out to be fake when they fall off.

Asmodeus captures Maria and tries to make her submit by feeding her an aphrodisiac, but the now lust-maddened Maria overpowers her and ties her up. Maria tortures her with a vibrator and says she is now Asmodeus' master, which Asmodeus enjoys.

Michael (Faith) finds a random human across the street and picks him as her personal candidate to be the Messiah. Shortly afterwards, she moves in with her candidate and starts training him like a soldier to fight the demons. As harsh and strict Michael is, her candidate manages to get into her good graces by cooking her favorite meal, omelettes.

Uriel (Patience) chooses an office worker as her Messiah candidate and begins stalking him throughout his daily routine, which begins disrupting his ability to do his work and eventually gets him fired. As the candidate attempts to find a new job, Uriel, having concluded that she has fallen in love with him, moves in with him.

Raphael (Temperance) becomes acquainted to a young man selling pastries in a street. After eating some of his cupcakes, Raphael excitedly begins helping him bake and sell more pastries, which ultimately become a success. Hearing of the human's dream of becoming a master pastry chief, Raphael realizes that being a Messiah will prevent him from following his dream, so she refrains from recruiting him and erases his memories of her.

Sandalphon (Diligence) chooses a student as her candidate and helps him study for an exam using her inventions and asking advice from Belphegor. Despite Sandalphon's machines and her own physical attractiveness giving him trouble to focus on his studies, the candidate ultimately, albeit barely, passes his exam.

Metatron (Charity) works as a nurse at a hospital to treat her candidate but realizes that she doesn't know anything about being a nurse, so she resorts to simply using her body to clean him up and make him feel better. While the candidate is initially glad to be serviced by her, she quickly turns into a sexual sadist upon touching a needle, which ultimately makes him worse.

Gabriel (Chastity) is lecturing a crowd against engaging in sexual activities when she spots her candidate. She immediately moves in with him and tries to clean up all of his immoralities - ranging from stealing his porn to dictating what foods and clothes he can have.

Michael then joins the Virtues in returning to Heaven, saying they will try again in another city.

Sandalphon and Metatron test a candidate by strapping Uriel to a table and having mechanical arms strip and molest her to see his reactions. He fails the test by becoming aroused and is dropped through a trap door. Sandalphon and Metatron wonder if they will ever find the Messiah while Uriel is humiliated by her experience.

Michael orders the other Virtues to train with her in the park by fighting with water guns improve their aim and dodging ability, using a device invented by Sandalphon to make them invisible to onlookers. When they don't take the training seriously and just playfully spray each other, Michael enchants the water to dissolve clothing to motivate them. By the end, they are all rendered naked, then the device breaks, exposing them to the crowd and humiliating them.
