Welcome to Demon-School, Iruma-kun : Season 3

The students of the Misfit Class have been given a special order. The order was for all of them to reach the Dalet rank before they become second-years, or they would lose the Royal One that they had worked so hard to obtain. The next event where they can raise their rank is the Harvest Festival. In order to help them raise their ranks in such a short amount of time, the school had prepared special tutors for them. The new term had only just begun, but unexpected trials await Iruma and his

Iruma and Lead end up being trained by Robin's relative, Barbatos Bachiko. Bachiko is very skilled and was personally asked by Sullivan to assist Robin with tutoring the kids. They were supposed to have a rather hard training schedule... but all Bachiko asks them to do is random errands. Lead has had enough of that and goes back to Robin. Iruma is left frustrated and alone. He learns that Asmodeus and Clara have been training and decides to take matters into his own hands!

Bachiko finally starts training Iruma, on one condition. Bachiko is known to be one of the best archers in the underworld and she tells Iruma he'll have to make a bow of his own. Iruma transfers some mana into one of the feathers of the guardian of Cutthroat Valley that he finds at the Magical Apparatus Battler and creates a bow. But Bachiko tells him it's not good enough. Bachiko tells him that the most important thing is to visualize the bow that he wants the most, but...

The final battle for the Babyls first-years, the Harvest Festival, finally begins. It is a rank-advancement exam in the form of a survival game that takes place over four days. They must hunt the various magical beasts and plants that exist in the jungle for points, and the one who comes out with the most points wins. The Misfit Class just finished some rigorous training, and they end up back in the groups they ended up training with, butting heads with everyone else. Onward to the jungle filled

Asmodeus and Sabro have been using their brute strength to capture their prey so far in the Harvest Festival, when they run into the Dorodoro Brothers, Ichiro and Niro, who are two of the favorites to win the whole competition. The brother issue a challenge, saying that they will hand over all of their points if Asmodeus and Sabro win against them. Meanwhile, Keroli and Camui have taken the lead in their own section by taking command of most of the magical beasts in their area and Jazz and

Iruma and Lead are leisurely eating their ingredients while the other members of the Misfit Class are earning points. Iruma was experiencing a survivor's high after having his life put in danger. They decided to enjoy their time eating, putting a priority on surviving the longest in the Harvest Festival. They start talking about memories of a devi-mixer they went to and are just enjoying their time. However, they are suddenly approached by a mysterious kigurumi and...

"Clara's Toy Box": Iruma gets sucked into Clara's kigurumi and then is trapped inside the strange and fantastical world that's inside! Iruma turns into a child inside and out and he ends up having a lot of fun with Clara. "A Night Filled with Screams": Students start forfeiting left and right due to the harsh conditions in the jungle the first night of the Harvest Festival. Meanwhile, Konatsu, Haruno, Azuki, and Dosanko manage to find a certain location and...

"Can We Make 100 Friends?": The owner of the amazing castle in the middle of the jungle was none other than Picero! Picero and Goemon were fighting in the Harvest Festival and had this castle to come back to. A busybody and a demon who marches to the beat of his own drum... This unlikely pair apparently have known each other for a while... "The Students I'm Proud Of" Meanwhile, in the tutors' tent, there was a party going on. The tutors were all watching their students' performances during the

The Dorodoro brothers provoke Asmodeus and Sabnock so much that they lose control and accept their challenge. However, their loss of control appears to be magical in nature...

Day 2 of the Harvest Festival, and the Iruma and Lead team were still at zero points, so they decide to try to get the Legendary Leaf to turn things around. With that in mind, they go visit Camui. Once they find him, they also encounter a horde of magical beasts and a little kingdom that had been established. The two are captured and suddenly brought in front of the queen of the kingdom, which just so happened to be Keroli?! Meanwhile, Ameri was thinking back about her time at the Harvest

Ameri happens to run into Jazz and Schneider in the tent for all of the students who have forfeited. Apparently, they ran into a plot to get rid of all of the students of the Misfit Class from this competition. Around the same time, Iruma and Lead had begun looking for the Legend Leaf by using the lyrics to the Legend Leaf song as a clue. Iruma goes through the jungle, following what the lyrics said, and finds an entrance to an underground labyrinth. Deep within the labyrinth filled with traps

Iruma is trying to get back to the surface after exploring the underground labyrinth with Naphura. On their way up, he runs into his parents that shouldn't be in the netherworld. They're actually an illusion created by Orobas's magic. Iruma is overwhelmed by the illusion and falls off a cliff. Down below, Iruma continues to see nightmarish illusions. Will he be able to overcome his fears?!

The third day of the Harvest Festival. The announcement of how many points each has is announced through the jungle. Kalego mentions that a certain student still has zero points and tells them to shape up. After hearing this, Asmodeus and Clara immediately think of Iruma. Meanwhile, down in the underground labyrinth, Iruma figures out a way to get out...

Iruma is safely reunited with Lead. But apparently, Lead had the Vase of Endings he had successfully obtained stolen by Elizabetta. However, it appears as though the one who took the vase was not Elizabetta, but someone else. Lead uses his bloodline ability, Controller, that had been strengthened through Robin's training and tries to track Elizabetta down. What he ended up hearing were the voices of Elizabetta, Clara, and Keroli in a hot spring?!

The battle between Keroli's Magical Beast Kingdom and Picero and Goemon's squad continues. Elizabetta also joins the Magical Beast Kingdom and charms the enemy male students on the frontline. Meanwhile, Iruma and Lead also arrive at the Magical Beast Kingdom. After having Camui interpret what Naphula was saying, they find out that it was Orobas who had been attacking the members of the Misfit Class. Orobas seems determined to win, no matter what. Clara is now in danger, as she wandered off into

Asmodeus protects Iruma and Clara from Orobas, but he is disqualified from the competition because he directly attacked Orobas. As they watch Asmodeus walk off, they realize that Orobas has disappeared. Ocho had taken Orobas and fled. If Iruma and his friends don't retrieve the Vase of Endings, they can't make the Legendary Leaf bloom. But they have no idea where to even start. It is then when a certain someone appears before Iruma and his friends!

The Harvest Festival is coming to an end. Iruma and his friends have managed to obtain the Seed of Beginnings and the Vase of Endings. But they have no idea how to make the Legend Leaf bloom. Lead then remembers one of their old lessons with Suzie and remembers a certain spell... Iruma and Lead have exhausted their energy and mana at this point. Will they be able to successfully make the Legend Leaf bloom in the little time that they have?! Finally, the results are announced. Who will be the

The Legend Leaf exploded in the sky and bloomed into beautiful flower petals. While everyone's in a celebrating mood, the award ceremony begins. Those who did excellently in the event, those who ended up forfeiting... How did all of the members of the Misfit Class do? Were they all able to reach the rank they needed to?! All of the mentors also are reunited with their students. How will the mentors respond to their students' performances during the Harvest Festival?

The night that the Harvest Festival ended, the instructors of Babyls got together at a pub to celebrate. Kalego usually never goes to these outings, but Balam catches him and forces him to go. Robin is getting ahead of himself as usual and the group even talks about Kalego's days as a newbie instructor. What is the most important thing about being an instructor at Babyls? We also get to see what happened to Ocho after he escaped into the jungle after the Harvest Festival.
