It's summer. Beth sprawls in the shade and our devil Jashin-chan hogs the fan. Unable to deal with the heat, Jashin-chan summons and bullies Kori-chan the Ice Devil to cool things down...up to a point. Meanwhile, not one soul helps Pekola who's about to faint, but an unexpected savior appears! Watch Pekola try Bondy's curry for the first time and Jashin-chan and Medusa's long history unfold.

While the town dances with Christmas spirit, Pekola wanders the streets with a bag full of bread crusts and a carton of milk. Bad Santa Jashin-chan steals Pekola's precious food and as punishment, Yurine turns her into a tree and Beth's feast for the holy night. The surprise visitor turns out to be Kori-chan's sister Yusa and Jashin-chan and Medusa's relationship reveals itself to be questionable.

Akihabara, the mecca of otaku, is also home to the Gachapon Hall. There, Mei Tachibana, the super cop of Banzaibashi Police, begs Yurine to give Jashin-chan to her and threatens to kill her if she doesn't. Mei swings her sword at Jashin-chan. While completely flustered at the fatal attraction, Jashin-chan still manages to take despicable actions which triggers Medusa's "passive-aggressive mode."

After a failed hunt for the second volume of a grimoire in Jinbocho's bookstore district, Jashin-chan and Yurine enjoys lunch at Jiro. Yurine buys take-out for starving Pekola, who is hesitant to accept since she houses the devil. When Pekola finally decides to eat, Jashin-chan had devoured it all. Minos and Jashin-chan's past and Pekola's job is revealed as super cop Mei makes a comeback.

Jashin-chan whips up pork cutlet curry for dinner one night, then hamburg steak curry the next, then croquette curry on the third night. Yurine calls her out but Jashin-chan's not listening. Our Ice Devils Yusa and Koji are back in town while Pekola encounters her unexpected nemesis. Jashin-chan's dropkick saves Pekola, making her feel overcome with gratitude for the devil.

One afternoon, Jashin-chan was on her way back from the grocery store for Yurine's Polar Bear almond jelly when Poporon attacked her with the Light Sword. Mean, cowardice, lousy, and sly, Poporon's much like Jashin-chan, even though she's an angel. Jashin-chan repels vengeful Poporon by devouring her halo. Will she gain angel powers from it?

Jashin-chan's voice echoes throughout Jinbocho, "Lost again, damn it!" She lost the grocery money by playing the slots and is desperate to make Medusa lend her more. Infuriated, Yurine swings her morning star, "I've no choice but to kill you." Turns out Jashin-chan's addicted to social-network games too. As Halo-less Poporon and the Ogre of Setsubun appears, Jashin-chan finds herself in a loop.

After her 17,711th loss, Jashin-chan runs to the bank to withdraw Medusa's cash to fund her gambling habit and "rewrite history." Instant karma leads them into a bank robbery and Jashin-chan just wants to save herself while Medusa stands against the robbers to save the people. Jashin-chan's asshole-ness peaks as Minos is more popular with humans and Poporon disguises herself as Noelle Amatsuka.

Charity workers ask for donations at the station as Pekola walks by with her well-earned pay. Tragedy strikes as her money vanishes into the donation box and her last 2,000 yen gets wasted for curry nanban eaten by Jashin-chan. Yusa and Koji reappear and Pekola works as Poporon's bodyguard. Valentine's Day stirs things up between Jashin-chan and Medusa and Jashin-chan's sleaziness goes on parade!

Jashin-chan's killer dropkick hits Yurine, the finale is here! Turns out, Yurine's down with a cold. Ecstatic, Jashin-chan fantasizes of returning to Hell, but ends up taking care of her with Minos and Medusa. Pekola, Poporon and Mei join them for a flower viewing. After a devilish relapse at the bakery, Persephone II finally finds Jashin-chan, only to bid farewell as she floats off into space!

One day, Jashin-chan remembered the day she was summoned to Yurine Hanazono. As long as Yurine is alive, she can't go back to the makai. So, Jashin-chan writes Yurine's name on "Noto", and this time she tries to decide the drop kick to Yuri. On the other hand, in front of Pekola and Poporon, a former subordinate's pit appears. Pekola is pleased that the Lord has finally picked them up, but the weapon was held in Pino's hand.

Jashin-chan found herself being fueled by "kuz" and "patincus" on SNS, and she was trembling with humiliation. Then, Jashin-chan took the item "1000 2000 drop" of the makai which was able to know where the man of the purpose was when it was noted from Medusa, and headed for revenge to the world. At the same time, Pekola who was attacked by Pino asks for help from Jashin-chan, but Jashin-chan is away.

Yusa, the ice devil, came to Yurine with Jashin-chan. Yusa pleads for her sister, Koji, to look for her because she is missing. Jashin-chan reluctantly called Mei to tell him about Ice's characteristics and asked her to search, but in fact, Ice-chan was brought into Mei's house. Mei is considering how to preserve formalin pickles, taxidermy, mummies, etc. in order to add cute and irresistible ice to his collection.

Yurine confesses that she once wrote "dictator" in a composition about "future me." I want to destroy anything that is against me and create a "Yurine Kingdom" that gathers only those who pledge allegiance. When I found out that Persephone II was thinking, Jashin-chan was shaken by fear and tries to get rid of Yurine. Another day, the group came to swim in the sea with a private beach ticket that was again awarded by Fukudome in the shopping street. And Jashin-chan in the swimsuit had legs again...!?

Yashin-chan, who smelled the pouch of the appendix of the magazine that Yurine had bought, remembered her childhood memories of spending thousands of years ago with Medusa and Minos. Medusa used the pouch of the 100 yen shop that Jashin-chan bought as a contact bag. However, classmates' goblins were ridiculed as "cheap and smelly". Jashin-chan who saw Medusa crying by one person trembles with anger.

Poporon, who sang and danced as an idol "Noser" on a glittering stage, used Pekola in the dressing room like a lower me. Poporon says that he invited Persephone II, the daughter of Hades, king of the underworld, to perform because he pretended to be good friends, made him watch out, and obliterated him. Meanwhile, Kyon-Kyon tries to find the mother of a lost girl, but is cold and hurt by the mother she finds. Ran-Ran gently encouraged such Kyon-Kyon.

One day, Pino made the most of his skills in the Tenkai Sweets Making Contest Grand Prix, handmade apple pie, and brought a hem to Yurine with Jashin-chan. Just as Jashin-chan was making cheesecake by hand, she was surprised at the deliciousness of the bite and burned her rivalry. On the other hand, Jashin-chan knew that something like garbage could be sold on the flea market app, and when she listed real garbage as a trial, it was successful! So I went to pick up garbage bags in the city.

Because Medusa and his children were absent at the Makai festival, Jashin-chan remembered her elementary school days thousands of years ago while chewing on loneliness. Minos, who had just transferred, had distanced himself from his classmates because he looked ferocious, but Jashin called out with Medusa to play with him, and he quickly broke down. But now, Jashin-chan can't go back to the makai, and she's all alone. At the curry shop, I was filled with loneliness so that I could see the illusions of Minos and Medusa.

For horse racing, Jashin-chan borrowed 100,000 yen from Medusa, but by the day before, he had already 40,000 yen, and he had 10,000 yen left. Jashin-chan loses 10,000 yen she got from Medusa at pachinko, but on her way out she encounters Kyon-Kyon and gives her some strawberry milk candy to see if it's poisonous, but it turns Ran-Ran back into her original form! Jashin-chan asks them to thank her by giving her 100,000 yen, and they start to before Ran-Ran turns back into a panda, although disappointed, they now have hope that they can find the end to the curse somewhere in the human realm. Back at home later, Jashin-chan discovers that Yurine actually has volume 2 of the grimoire, so can she finally return home?

Jashin-chan calls over Medusa and Minos, and confronts Yurine about why she has been hiding the book from her. The devils believe it to be because Yurine wanted Jashin-chan to stay with her, but Yurine explains it was only because it doesn't actually have the return spell in it, as it is in another book. Kyon-Kyon comes over later and explains the backstory of Ran-Ran's curse. Later on the devils and Yurine have a snowball fight, then everyone shows up to join the fun!

Akihabara has become one of the largest otaku cities in the world, becoming a city of electricity from the black market after World War II. About 1km to the west of the town, there was the world's largest bookstore district and an apartment where Jashin-chan lived. From the day she was suddenly summoned from the makai, Jashin-chan missed the irreplaceable days of tears and laughter that ran through with Yurie. It was Jashin-chan who tried to go to pachinko, but I remembered that there was a song that lasted about 10 minutes.

Jashin-chan decides to change her character for the beginning of the anime's third season. Seeing her new, serious expression seems to influence Yurine and the other characters, as well... Meanwhile, Pekola welcomes the New Year hungry, as usual. She visits Yurine's house after receiving an invitation to eat ozoni, but for some reason, the gang breaks into a karuta game before they start the meal. The game then progresses into a battle between devils, angels, and humans...

Now that Pino has been run out of Heaven, she fears that someone will be coming from there at any time to eliminate her. She heads to the park, where she hears Yurine's angry voice. Startled, Pino looks over to see Yurine's fist flying toward Jashin-chan... but striking a little girl instead. Yurine panics when she realizes what she's done, but the child seems unfazed. Pino then realizes that the child is Lierre, the God of Heaven, on a visit to the human realm.

The many sides of Jashin-chan are holding a meeting within Jashin-chan's head. It seems one of the attendees believes that Jashin-chan is incapable of ever beating Yurine, and the "original" is intent on rooting out the traitor, but they all begin to suspect each other and an argument ensues. Later, Yurine and Jashin-chan come across a Jizo statue by the roadside, and Jashin-chan eats the mikan that someone left there as an offering. Yurine warns her that she may incur karma's wrath for stealing an offering to a god, but Jashin-chan doesn't listen...

Jashin-chan is helping Pino for once, by raking up fallen leaves. Once she has swept them into a sizable pile, she smiles suspiciously as she looks at them, seeming to formulate a plan... Days later, Jashin-chan is walking down the street, visibly frustrated, when a great idea hits her! She hides in Yurine's room disguised as a statue while Yurine is away from home. But when Yurine returns home and actually doesn't seem to notice the statue's true identity, Jashin-chan is so surprised that she loses sight of her plan...

Jashin-chan is excited to learn that her beloved childhood teacher, Persephone, is coming to visit.

When Jashin-chan runs away to escape debt collectors, the gang heads to Kushiro, Hokkaido, to find her.

Jashin-chan's flight from debt collectors takes her to Obihiro, Hokkaido, where she continues trying to make a quick fortune.

Jashin-chan continues to flee from debt collectors, this time ending up in the southern coastal town of Minamishimabara.

As the gang explores Furano, Hokkaido, the weight of Jashin-chan's debt begins to push her and Medusa to the brink of despair...

Jashin-chan comes home to find Yurine gone, and begins to wonder if she's finally abandoned her.

Jashin-chan recalls all the naughty things she did as a child, and decides to donate blood to make up for them.

Princess Ecute of the vampires tries to get Yurine to join the vampire clan, and Jashin-chan is determined to stop her.
