Iruma had finally started getting used to his new life, but 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.

Jealousy strikes as a friend's secret is revealed, putting the concert in jeopardy. Can Iruma save the show?

One of the most popular idols in the netherworld, Kuromu-chan, holds an all-day concert at the Makubari Dome. Iruma just happened to be lucky enough to get tickets for her concert and takes Asmodeus and Clara with him!

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 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!

Iruma faces Kiriwo's true form, as the plan to destroy Babyls reaches a critical point.

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.

Kiriwo dreams of a world where all demons are equal, regardless of their magical powers. Iruma agrees, so he proposes they shoot for the grand prize at the Battler Party so everyone would see how hard Kiriwo and the Magical Apparatus Battler worked

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 all over Babyls until he finds a mysterious hidden room.

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...

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.

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 faces his fears in a lesson with familiars, only to find a new challenge awaiting him.

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?

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 finds out it's rather similar to a game they play in the human world.

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?

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."

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, which ends up bringing even more attention to him again.

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.

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.

Iruma meets Clara, a peculiar girl, and stands up for her against bullies, deepening their friendship.

Iruma 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!

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 ends up becoming Sullivan's grandson!
