Suzuki Iruma is too nice and just doesn’t know how to say no. One day, he somehow gets dragged into the netherworld where the demons live. He arrives at the great demon Sullivan’s mansion where he is asked to do the unthinkable... and ends up becoming Sullivan’s grandson! He is quickly enrolled into the Demon School Babyls where Sullivan serves as chair-demon. Iruma begins his super exciting school life at demon school while trying to conceal the fact that he’s a human!

Iruma, who is going to Babirusu, wants to spend calmly so that he will not be noticed by humans. However, the entrance ceremony and a case with the entrance examination chief Asmodeus Alice have already attracted the attention of the students! First-year students Iruma and others decided to participate in the "Familiar Summoning Ceremony" event to determine the rank of the devil. The person in charge is Naverius Caluego, an extremely strict instructor in Babiru's. What kind of familiar is Iruma summoned?

Part A: Iruma and Asmodeus encounter a rather strange girl named Valac Clara. Because of her friendly yet strange demeanor, some students seem to be taking advantage of her...

Part B: Iruma had become closer to both Asmodeus and Clara. They started picking him up from his house to walk to school together and Iruma was still trying to get used to demon life. One day at lunch, some kids try to pick on Iruma, but...

Iruma, Asmodeus, and Clara end up in the Misfit Class. As the name suggests, the class is filled with a bunch of misfits and Sabnock Sabro, who wants to become the next Demon King, declares Iruma his rival. Their classes start and their first lesson is a flying race. The race was to take place in the Warbling Valley and the Cutthroat Valley. Apparently, there’s also a demon bird that lives there...

The Misfit Class is in the middle of a flying race in order to determine their ranks. Since Iruma is human, he can’t fly, so he’s riding on the back of the giant baby demon bird, but it seems to be flying off course. Meanwhile, Sabnock decides to go through the treacherous Cutthroat Valley and ends up having to battle it out with the Guardian there. Sabnock is obsessed with becoming the next Demon King, but why is he so obsessed? Are Iruma and Sabnock going to be able to make it out of Cutthroat Valley alive?

Iruma obtains the Gluttonous Feeder ring which feeds upon the magical powers of others. Iruma is still doing everything he can to not stand out at school, but an incident occurs in class involving the ring, which ends up bringing even more attention to him again. Meanwhile, a certain demon was wondering if Iruma was actually human. That demon just happens to be the student council president, Azazel Ameri. But there’s a very unique reason that makes her think Iruma is human...

The one who had bumped into Iruma in the hallway was Ameri, who had been convinced that Iruma is human. When they bump into each other, Iruma finds out that Ameri has a shojo manga from the human world called “First Love Memories.” “First Love Memories” is considered forbidden texts in the netherworld. Ameri desperately wants to know what they’re saying in the manga so she asks Iruma to read the text for her, which would also prove that he’s human. Thus, began Iruma and Ameri’s live readings!

Clara isn’t amused at the fact that Ameri keeps summoning Iruma. To try to get Iruma to pay attention to her again, Clara starts to take succubus charming lessons with the succubus teacher Raim. Clara wants to get Iruma’s attention again, but apparently her sexiness is almost nonexistent. Even then, Clara sets out to charm Iruma. Will she be able to win Iruma over?

After making a promise with Ameri, Iruma sets out to try to move up a rank. Iruma finds out that there is a promotion exam in a week where they would play execution cannonball, and he also finds out it’s rather similar to a game they play in the human world. Iruma decides to train after he realizes he’s far weaker than anyone else in his class. Iruma decides that he’s not going to use magic, so he starts an intense training regimen with Opera. What does Iruma gain at the end of all this training?

The day of the rank promotion test involving execution cannonball had arrived. Iruma is ready for the match, but then ends up on different teams with Asmodeus. Despite that, the game continues with all his other classmates using their various forms of magic to play the game. Will Iruma be able to show off the results of his training?! And who will win? Iruma or Asmodeus?

Part A: A new teacher named Balse Robin, who is quite innocent and fearful of nothing, arrives! His first lesson involves interacting with familiars. Iruma turns pale at the thought of this lesson since his familiar happens to be Kalego, but...

Part B: Iruma decides his next goal now that he’s moved up a rank. Apparently, there are groups at Babyls where like-minded demons gather called Battlers. Iruma shows some interest in Battlers, but then is greeted by a terrifying sound...

The Battlers’ recruiting operation, the Rookie Hunt, had begun. The seniors all come out to try to find worthy first-years to join their groups. What takes place is an immense battle! Iruma and his friends somehow make it through, but then decide to check out the various Battlers on campus. But then suddenly, Iruma’s ring goes berserk, causing him to run into a senior...

Iruma runs into his senior Amy Kiriwo in front of the Magical Apparatus Battler again. The Magical Apparatus Battler room is filled with all kinds of strange gadgets. There, Iruma hears about Kiriwo’s dreams. Babyls is about to hold their annual Battler Party where all the new students get to promote the Battler they joined. Sullivan looks forward to seeing Iruma-kun but while he’s at the Thirteens’ Dinner...

Sullivan is apprehended by the Demon Border Patrol on suspicions of unlawfully entering the human world. He still hopes to somehow make it to the Battler Party to see his precious Iruma-kun... Meanwhile, Iruma had no idea what was going on with Sullivan and was preparing for his presentation for the Battler Party. After going through several ideas, they decide to create things called fireworks that are supposedly from the human world and they spend the night at school to create them. And so, began the fun sleepover for the MagiApp Battler kids.

Iruma and the others continue to prepare for the Battler Party. The launchpad for the fireworks is almost complete, so Iruma goes to look for Kiriwo. Suddenly, Iruma’s ring starts dragging him and is led all over Babyls until he finds a mysterious hidden room. Kiriwo was behind those doors planning a certain project. We also find out exactly who Kiriwo had been talking to on the phone. What does Iruma find in the mysterious room?

Kiriwo’s dream: To make a world where all demons would be equal, even if they didn’t have that much magical powers. Iruma completely agreed with this statement, so he proposed they shoot for the grand prize at the Battler Party. If they’re able to get the grand prize, everyone, including high-ranking demons, would see how hard Kiriwo and the Magical Apparatus Battler worked. All the Battlers are getting their presentations ready for the Battler Party on the day of the Party Eve. But suddenly, the fireworks shell that Iruma and others prepared suddenly goes missing...

Suddenly, all of Babyls is surrounded by invisible walls! On top of that, they are unable to get a hold of the outside and there are invisible walls that popped up all over the school. Amidst all the chaos, Kalego and the other teachers have the students take shelter in the central plaza. Since Kiriwo is missing, Iruma decides to go look for him with the help of Asmodeus and Clara. Will Iruma be able to find Kiriwo?

Kiriwo’s plan to destroy Babyls continues to move forward. Iruma somehow made it to the hidden room. Kiriwo looks completely different than what Iruma is used to, and Kiriwo proclaims that he’s going to use the fireworks that the Magic Apparatus Battler created to blow Babyls up...

Kiriwo then tells Iruma about his childhood. Iruma sees the true demon side of Kiriwo. Will he be able to save Babyls from this crisis?

Part A: When Iruma woke up, most of the ruckus was already over. Sullivan tells Iruma that Kiriwo had been arrested. What happened when the giant fireworks went off?

Part B: The ordeal at Babyls comes to an end. The Battler Party is finally about to start! The students all do their best in order to get the Grand Prize, and the students' families come by to enjoy the festivities!

Part A: The ceremonies to give out the prizes for the Battler Party has now begun. Iruma and the other members of the MagiApp Battler hope to get the Grand Prize! That was also what Iruma had promised Kiriwo. Who will the prize go to?

Part B: Iruma happens to stand out more after the incident with the fireworks. The head of the Demon Border Patrol, Azazel Henri, begins to suspect that Iruma may actually be human and he visits Babyls. Wait, this all seems rather familiar...

One of the most popular idols in the netherworld, Kuromu-chan, holds an all-day concert at the Makubari Dome. Dem-dols have the important job of helping demons release the stress and evil desires they feel during their Evil Cycle. Kuromu was considered a shining new star in the field, and her tickets would usually sell out in one day. But she actually had a secret that she couldn’t tell anyone... Iruma just happened to be lucky enough to get tickets for her concert and takes Asmodeus and Clara with him!

Kuromu’s true identity happened to be Crocell Keroli from the Misfit Class! The more Keroli talked to Iruma, the more she became jealous about how popular he is, and she ends up collapsing. There was no way that Keroli could continue with the concert, but she had a reason she could not cancel the concert. In order to somehow still make the concert at Makubari Dome a success, Iruma and his friends do something rather surprising!

Iruma had finally started getting used to his life in the netherworld. As he continues having fun with his classmate, he begins to wonder if he should really be allowed to stay in the netherworld. Seeing that Iruma seems troubled, Asmodeus and Clara decide to cook for him. But Clara’s mother’s recipe is filled with items that even Asmodeus doesn’t know about. The two end up having a cooking competition. Which dish will Iruma choose?

Due to very bizarre circumstances, the human boy, Suzuki Iruma, ends up in the netherworld. He is keeping the fact that he is human a secret and attends the Demon School Babyls. Because he is human, he cannot use magic so he had been using the Gluttonous Feeder Ring to get by in school. But then one day, the ring started to speak! Why, though? Iruma then meets the incarnation of the ring who calls themselves Alicred, AKA Ali-san.

The Magical Apparatus Battler is put on hiatus due to Kiriwo's absence. Ameri agrees to let them reinstate the Battler, but first, the three members must experience other Battlers. Asmodeus is sent to the New Magic Battler, Clara to the Game Battler, and Iruma joins the student council. Iruma now has to face the grueling training and schedule of the student council. Meanwhile, something sinister is after Ameri...

Someone had done something to change Ameri's personality! She's usually confident and stern, but now, she's now meek and dainty and the student council can't hide the fact that they're not sure how to handle the situation. While all this confusion is going on, Ronove Romiere, the president of the Disciplinary Battler comes to try to steal Ameri's position. He proposes a dissolution election against the student council. Who is behind the changes in Ameri? What will be the result of the election?

Ronove declares that he's going to take the position of student council president by holding a dissolution election. But due to a spell that someone has cast, Ameri is unable to be her usual confident self and is very meek. Iruma then tells her something she had told him in the past to try to give her confidence. What kind of speech will Ameri present while all of the attention is on Ronove. What is the emotion that Ameri was able to find deep within her heart?

After finishing his time at with the student council, Iruma finally goes back home. Sullivan is ecstatic that Iruma came home and throws him a welcome home party. He tells Iruma to invite Asmodeus and Clara and they all have a fun time. Sullivan ends up getting last in a dance competition they have and he then conducts a Dark Parade so he can make himself look cool to Iruma...

Ali-san forces Iruma to go through his evil cycle. His classmates are both in shock and admiration in how much more confident Iruma seems. Meanwhile, Iruma realizes how terrible of an environment the Misfit Class's classroom is, so he proposes something to Kalego. His proposal was to move the Misfit Class to the classroom with the utmost importance at Babyls, the Royal One! Despite the rather sudden and ridiculous request, Kalego agrees if Iruma is able to fulfill certain terms.

The Misfit Class must gather approved permission slips from all of the faculty members within three days to move to the Royal One. Iruma is currently going through is evil cycle and figures out a plan to have the rest of the Misfit Class members use their abilities to get approvals from the faculty members that might be less likely to say yes to their transfer. The first one to use their ability is Andro M. Jazz! Will Iruma's plan turn out to be a success?

With the help of the classmates and others, Iruma and the Misfit Class are able to get approved permission slips from all of the teachers and appear before Kalego. However, Kalego doesn't seem to want to stamp his own seal. He then points out something they missed in their agreement. Iruma and the Misfit Class were about to give up their transfer to the Royal One, when there's a knock on the faculty room door...

The students are about to welcome their version of summer vacation! The Misfit Class is super excited but then, they're reminded that if they don't do well on the end of terminus exams, they'll have to stay for supplementary classes during their break. To avoid that from happening, they all want to avoid failing. But Iruma is a human and has very little knowledge concerning netherworld wisdom. To avoid failing, Iruma works with Asmodeus and Clara to study!

The instructor for the study of imaginary beasts, Balam Shichiro, can't help but touch any living creature he comes in contact with. Because he looks rather terrifying, the students are generally pretty scared of him. During class, Balam notices that Iruma doesn't have wings on his back. If it's found out that Iruma is a human in the netherworld, only trouble awaits. But despite all of this, Iruma says the most surprising thing to Balam...

The end-of-terminus exams are finally upon them! Will Iruma and the rest of the Misfit Class be able to avoid failing and having to take supplementary classes? Meanwhile, Ameri is excited for her usual reading session with Iruma when she's suddenly visited by Clara. Clara then drags Ameri off to meet with Elizabetta and Keroli and they have some girls' time. They start talking about relationships and things start to oddly heat up...

Kalego is forced to go visit all of the homes of the Misfit Class due to Sullivan's orders. He wants to get this over with as soon as possible but considering how unique all of his students and their families are, he has trouble finishing this quickly. He finally gets to Iruma's home, which is Sullivan's mansion, and he seems to be on guard. It appears that there's somewhere here who he's known since high school, and...

The Misfit Class finally gets to go to Walter Park on their vacation. Kalego, Balam, and Opera go as their bodyguards and chaperones while Ameri thinks Iruma is asking her on a date and also joins in. They split up into three teams and see which team can have the most fun at the amusement park!

Walter Park is filled with so many fun things! All of the students do their best to have the most fun so that their team can win their competition. Clara and Opera's team has fun trying on cute clothes, and Jazz and Kalego's team tries their hand at shooting games. Each team happens to meet members of the Walter Park staff and continue to have fun. Iruma and Balam's team is joined by Ronove but Iruma ends up having too much fun and getting lost and ends up going down a shady looking alley!

The Walter Park staff that Iruma and his friends had encountered were actually the terrorist group, the Six Fingers, who planned to destroy the park. The Six Fingers set three giant magical beasts loose on the park. The whole park is filled with fear and chaos. Jazz and the others on the Kalego team faces off with one of the beasts for some hands-on training. Meanwhile, Kiriwo's plan to escape from the prison below the park seems to be going smoothly.

Three giant magical beasts appear in Walter Park. Iruma, Asmodeus, and the others band together to face off with these creatures that ruined their fun day! Opera and Ameri fight against the giant rat while Jazz and his group are having some trouble dealing with the giant bull. He as well as other members in his group such as Lead and Camui don't have abilities suited for fighting, but Jazz comes up with a plan to turn things around!

The Balam team is trying to get to safety after saving some kids who weren't able to escape on their own in time. But then Asmodeus and Sabnock decide to fight the carmine dragon without telling anyone else. The two end up competing each other and fight the beast with their familiars. While they're fighting, Asmodeus ends up putting himself in great danger. What will come of the fight against Asmodeus, Sabnock, and the carmine dragon?

The 3 giant magical beasts combine to form an even bigger magical beast. Ronove uses his Charisma in order to draw the beasts attack into a different direction, but... As soon as the magical beast lets out its attack, Iruma and Ali-san step right in front of it! Everyone is panicked at Iruma's rather reckless move. How will this battle end? Meanwhile, Kiriwo manages to escape from prison and it becomes clear as to which demon assisted him.

Iruma couldn't get home after being named the hero who saved Walter Park and being hounded by the press, which leads to him and Asmodeus spending the night at Clara's house. Clara's house is located in Hubbub Forest, which is also home to various strange plants and creatures. Clara's family welcomes them with open arms and then they all go into the forest to find some ingredients for their meal. According to Mommy, the ultimate ingredient resides in Hubbub Forest...

Ameri carefully plans out her date with Iruma by going through guidebooks and her favorite manga, "First Love Memories." They are finally going on their date that she'd been dreaming of! They end up going to Aqua Case, an aquarium that is also a waterpark! Ameri tries to make various exciting things happen on the date with her secret plan, but everything she tries doesn't seem to be backfiring, and...

The end of terminus enters its final days. Iruma safely finishes his homework and is invited by Sullivan to go to Magical Street along with Opera. They browse around picking up things Iruma will need for his new school term. Iruma happens to overhear some demons talking and then asks Sullivan about the Demon King, since he is one of the most qualified individuals to become Demon King. What exactly does it mean to be the Demon King, the most powerful being in the netherworld?

阿布諾瑪班的學生們接獲特別指令。那就是全班的學生都必須在升上二年級前將階級提升至達雷斯＜４＞！否則就必須離開費盡千辛萬苦才爭取到的「王者的教室」。接下來即將開始的階級提升活動是「收穫祭」。為了讓阿布諾瑪班的學生們在短時時間內提升實力，學校準備了超強力的特別講師陣容。新學期才剛開始沒多久，入間等人就開始了超乎常理的特訓生活！

入間和利德開始在羅賓的親戚巴巴托斯．芭琪可底下展開特訓。芭琪可是受到薩利班的直接請託，以羅賓幫手的身分前來擔任講師的強者。原以為應該會開始一段艱辛困難的特訓生活，但是芭琪可命令入間和利德做的事情卻都是些跑腿和雜役的工作。忍無可忍的利德決定回到羅賓身邊。而留下來的入間也因為滿心的不甘而開始燃燒熱血。在得知阿斯莫德和庫菈菈都在努力進行特訓後，入間決定採取某項行動！

芭琪可終於答應為入間安排特訓。身為魔界弓術高手的芭琪可提出的條件，是要求入間做出屬於自己的弓。入間將魔力注入在魔具研究師團發現的金剪首領的羽毛中、製作出了屬於自己的弓。然而，他做出來的弓卻全都被芭琪可打了回票。芭琪可表示最重要的是對於「自己想要的弓」的想像…。

巴比路斯一年級生的最終戰鬥「收穫祭」終於開始了。收穫祭是為期約四天時間，採取生存競賽形式的階級升級考試。參加者要在限制時間內狩獵棲息在叢林中的魔獸和魔植物，累計分數最高的人即可獲得優勝。每天都在特訓中度過的阿布諾瑪班的學生們，對自己以外參加特訓的學生的競爭意識強烈、幹勁十足。現在，大家即將潛入危險的魔獸潛伏的叢林！

藉由壓倒性的武力狩獵獵物的阿斯莫德和斯伯諾克組面前，出現了優勝者的有力候補人選「多洛多洛兄弟」的伊奇洛和尼洛。多洛多洛兄弟向兩人提出了挑戰。並表示如果兩人獲勝就將持有的所有分數交給他們……？而在同一時刻，賈斯和修奈達正靠著戰略手段奪取他人的分數。他們在特訓期間度過的有如地獄般的日子究竟是……！？

正當阿布諾瑪班的其他學生正順利地賺取分數時，入間&利德組卻用在叢林中採集到的食材悠哉地吃著東西。入間久違地置身於需要意識求生的環境中，使得他現在「求生欲高漲」。兩人現在將如何存活視為第一考量，把收穫祭的活動擱在一旁、享受著充實的野外求生生活。過程中，兩人回想起過去曾經參加過「Devi聯」的事情，聊得非常起勁。然而在他們的身後，卻出現了朝著他們步步逼近的布偶裝身影……！？"

入間被庫菈菈的魔術捕捉並被關到了布偶裝裡頭，裡面是寬廣又不可思議的童話空間！身心都變成小孩子的入間開始和庫菈菈一起盡情玩耍！

收穫季第一天的夜晚到來。在叢林的嚴酷環境中陸續有學生棄權。過程中，已經累得氣喘吁吁的小夏、春乃、杏月和德莎子四人來到了某個場所……！？"

聳立於叢林中的城堡主人原來是皮克羅！皮克羅和五右衛門組建立起固若金湯的城堡在收穫祭中戰鬥。一人愛管閒事、一人我行我素，雖然兩人乍看之下個性不合，但他們似乎從以前就有交集了……？

講師們的帳蓬內現在正在舉行宴會。眾人看著現場直播，一邊守望著徒弟們的活躍表現一邊開心地喝酒——原以為是如此，但這群師父們似乎燃起了競爭意識……？"

阿斯莫德和斯伯諾克組正與多洛多洛兄弟進行著狩獵魔獸「百擊晃鶴蘋果」的對決。為了從兩人手中奪回自己的「師父」，自稱是師父頭號弟子的多洛多洛兄弟提出了決勝的要求。受到挑撥的兩人也接受了挑戰。然而接受了這對兄弟的挑撥其實正表示陷入了他們所設下的陷阱……。為了對抗這對兄弟，阿斯莫德使出了巴拉姆傳授的打架必勝法「惡週期解放」！這對兄弟與「師父」之間究竟有什麼樣的過去呢？

收穫祭進入至第二天。到現在都還是0分的入間&利德組為了一舉逆轉，決定以採集「傳說之葉」為目標。為了取得傳說之葉的線索，兩人前往拜訪卡姆伊。然後出現在他們眼前的，是率領為數眾多的魔獸所構成的王國！突然就被逮住的兩人被送至統御王國的女王凱蘿莉面前，眼看即將陷入危機！？另一方面，在現場直播的帳篷中觀察著入間的艾梅莉開始回想起自己一年級參加收穫祭時的往事……？

艾梅莉在棄權者的帳篷中遇見了賈斯和修奈達。他們似乎是成為了針對阿布諾瑪班的學生下手的學生狩獵者的犧牲者。同一時刻，在取得了有「傳說之葉」線索之歌曲的歌詞後，入間和利德開始分頭展開搜索。入間照著歌詞的內容在叢林中前進，並發現了通往地下迷宮的入口。在充滿阻擋入侵者前進的陷阱或機關的迷宮深處，等待著入間的會是……？

入間與納夫拉正以地上為目標在地下迷宮中前進。半路上，入間遇到了照理說不該存在於魔界的父母。其實，入間看到的父母全是歐羅巴斯利用魔術製造出來的幻覺。被幻覺震攝的入間不慎從懸崖掉了下去。而來到底層後，入間也不斷受到幻覺的折磨。他究竟能否戰勝恐懼呢！？

收穫祭第三天。公告學生們的獲得分數的期中發表廣播在整片叢林中響起。然後卡爾耶格針對某個獲得分數仍是0分、目前下落不明的「某個學生」講出了有如在搧風點火般的一段話。阿斯莫德和庫菈菈在聽見後腦中同時浮現出入間的身影…。而另一方面，入間為了從地下的深處逃出來所想到的方法是！？

入間順利和利德會合了。但是利德費盡千辛萬苦才取得的「終末之盆」似乎被愛麗莎貝塔搶走了。大受打擊的利德因此崩潰痛哭。不過，搶走盆栽的犯人似乎不是愛麗莎貝塔而是另有其人。利德利用和羅賓進行特訓而獲得強化的家系能力「感覺強盜」開始尋找愛麗莎貝塔的位置。然後，進入利德耳中的，竟然是正在泡溫泉的愛莉莎貝塔、庫菈菈和凱蘿莉的聲音！？

凱蘿莉率領的魔獸王國與皮克羅&五右衛門組的戰鬥持續進行著。過程中，加入魔獸王國陣營的愛莉莎貝塔讓前線的男學生們接二連三地喪失戰力。另一方面，入間&利德也抵達至魔獸王國。在請卡姆伊翻譯同行的拉夫納所說的話之後，得知連續襲擊阿布諾瑪班學生的人就是歐羅巴斯。歐羅巴斯對優勝抱持著強烈的執念。獨自一人進入叢林的庫菈菈恐怕有危險了……！

阿斯莫德雖然成功擊退了歐羅巴斯，但也因為違反規則而被迫棄權。入間在目送阿斯莫德離開後，回過神來才發現歐羅巴斯消失了。原來是奧喬歐帶著羅巴斯逃跑了。如果不取回「終末之盆」就無法讓傳說之葉綻放。然而，他們現在也沒有找出歐羅巴斯所在位置的線索。正當他們面臨窮途末路之際，某個人物出現在入間等人面前……！？

收穫祭再過不久後就要結束。入間等人取得了「開始之種」與「終末之盆」。然而他們卻不曉得最關鍵的讓傳說之葉綻放的方法。這時利德突然回想起以前在課堂上學過的某個魔術……。他們能在所剩無幾的時間內讓傳說之葉綻放嗎！？然後，終於來到了結果發表的時間。取得最多累積分數，得到收穫祭優勝者的稱號「少年王」之榮耀的學生究竟會是誰呢！？

傳說之葉在天空中炸裂，在四周灑下飛舞的花瓣。而表揚儀式也在充滿祝福的氛圍中開始了。參加者中有留下優秀成績的學生，也有被迫棄權的學生……。阿布諾瑪班的學生們究竟能否實現他們提升階級的目標呢！？而阿布諾瑪班的學生們也和各自的師父重逢。在收穫祭過程中一直看著徒弟們的活躍表現的師父們各自又都有什麼樣的反應呢？"

收穫祭結束的當晚，巴比路斯的教師們在某間居酒屋舉行慶功宴。平時絕對不會參加飲酒聚會的卡爾耶格也因為被巴拉姆抓住而強制參加！過程中羅賓像往常一樣得意忘形地喧鬧，大家還談起了卡爾耶格新人時代的逸事，聊得不亦樂乎。而羅賓接下來即將了解到巴比路斯的教師必須具備的心態是什麼。同時，收穫祭最終日，在叢林中逃竄的奧喬之後的動向也即將揭曉。

「惡友」入間帶著拜託家人買的新遊戲機到利德家玩。正當兩人玩著遊戲時，利德的姊姊夏姬突然闖入房間！夏姬的心情看起來好像很不好……？「真心料理教室」艾梅莉和入間決定一起製作手工餅乾，然而兩人卻沒有好好做過料理的經驗。兩人的料理過程連歐佩菈都不禁感到戰慄！

為了感謝芭琪可替入間進行特訓，薩利班招待她來宅邸作客。然後芭琪可從薩利班口中得知了「入間是人類」的事實。之後，入間照著先前的約定和庫菈菈一起來到阿斯莫德家玩。入間對於是否應該繼續向兩人隱瞞自己是人類的事實而感到煩惱。在得到阿斯莫德的母親阿斯莫德．艾姆莉莉絲的建議後，入間將會對兩人說什麼呢……。
