Decision! Class Rep (決定!いいんかい Kettei! Iinkai) is the sixth episode of Isekai Quartet. It was first broadcasted on May 14, 2019.


Roswaal is happy to see that everyone has adjusted to school life. Now he decides that it is time to select a Class Rep and Vice Rep. Albedo immediately votes for Ainz Ooal Gown to be the Class Rep along with the other Floor Guardians. Aqua objects, refusing to allow an undead to gain the position and votes herself for the title. Seeing that Ainz and Aqua are nominated for Class Rep, Roswaal asks if there is anyone else that's interested and is answered by Emilia and Subaru supports this. Drawing names like before, Emilia is selected as Class Rep. Albedo is furious that Ainz was not selected as Class Rep, though Roswaal states it was a fair drawing. Aqua, seeing that Class Rep is no longer available, drops out of the drawing, making an open slot for Vice Rep along with Ainz. Albedo and Shalltear Bloodfallen volunteer for the open position so they can work alongside Ainz. Soon Aura Bella Fiora and Mare Bello Fiore chime that they also wish to be Vice Rep. As the denizens of Nazarick quarrel, the men in Tanya's group, cannot help but feel jealous of the skeleton's harem.

Roswaal draws names and Albedo is revealed to have been selected as the second Vice Rep. In addition, several classmates have been grouped together into different committees. Animal Care: Subaru, Aura, and Aqua; Disciplinary: Tanya, Demiurge, and Kazuma; Lunch: Ram and Visha; Library: Mare and Beatrice; Gym: Cocytus, Darkness, Weiss, Koenig, and Neumann; Nurse: Rem and Shalltear; Intercom: Megumin and Grantz. As he leaves, Roswaal tells the class to get along.

Noticing that the Floor Guardians had been evenly divided among the teams, Demiurge has a thought, calls for the other Floor Guardians, and states that Ainz's order of world conquest is still in effect. The demon encourages his fellow Guardians to go along with the situation and be ready to use their findings of the other groups against them, stating that it is part of Ainz's order, much to the lord's chagrin. Roswaal, who has been listening from behind the closed door of the class, is approached by Beatrice. She tells him that she finds that the drawings result being fair is be ridiculous and accuses him of tampering with the results. The girl warns him to stop whatever he is planning, but the noble shrugs it off, stating they all have to play their part as he walks away.

Kazuma laments how he has died and become friends with a foolish goddess in another world. Now he finds himself in a world where he must be a student. He is seen in the classroom with the Disciplinary Team, where he is shown to be lying on the ground as Tanya and Demiurge watch him. He cries at the absurdity of the situation: a little girl and a demon being his classmates. Tanya asks when he will he move, to which Kazuma replies he cannot get up for some reason. A flashback reveals that Demiurge had cast control magic upon Kazuma to test its effects in this world. Demiurge notes that the power balance is a bit off as Tanya kicks the lying Kazuma. Satisfied with the results, Demiurge relinquishes control over Kazuma, allowing him to stand. As Kazuma rises up, unsure of what has happened, Demiurge offers to let him rest, which Kazuma accepts before being denied by Tanya. Tanya orders Kazuma to stand up using magic, causing him to immediately stand up. This surprises Demiurge as the demon sees that the human girl has the power to command others. Tanya declares that she will not accept any tomfoolery as long as she is part of the Disciplinary Committee and immediately suggests creating a list of rules to follow. Impressed, Demiurge agrees and suggests that they make a list of rules, which draws approval from Tanya, who praises Ainz for having someone like Demiurge by his side, much to the demon's appreciation. As the two become friends with each other, Kazuma declares that he might never come to school again.

Outside, the Gym Committee meets and Cocytus states that he will be head of the committee and everyone else agrees, seeing him as the strongest one present. Darkness is eager to start and starts spewing perverted fantasies such as binding themselves or throwing themselves into the mouths of giant toads. As Cocytus is about to comment on her eccentricities, she refers to him as a "Deadly-looking Metal Mantis Man," which makes him question her naming sense. She then imagines more perverted fantasies which involve Cocytus using his extra arms to help pin her down while he breathes cold air at her, much to Cocytus' confusion. Weiss asks Darkness to tone down her fantasies, but she instead adds him into her fantasy, stating that while Cocytus pins her down, Weiss will savage her with his eyebrows, much to Weiss' chagrin.
