Summary
At Kazuma's Mansion, Kazuma's party back from another adventure prepare to count their spoils. Aqua cries about wanting to take a bath to wash away all the Giant Toad gunk off her. However Satou stops her telling her they need to go through the items. A strange button device slips out of Kazuma's bag. In Nazarick, the Floor Guardians report to Ainz Ooal Gown on their progress in the Re-Estize Kingdom and the Baharuth Empire. Demiurge also reports of a strange phenomena happening within the tomb. Though he is unable to elaborate on it as he has not seen for himself, but knows it involves the appearance of a strange button with a switch on it. Ainz believes that they are under attack from an outside power which the demon agrees as it was able to breach Nazarick's defenses. Not taking any chances Ainz orders the Guardians to send an order to report any appearances of these devices and take trap-disarming measures.

Back with Kazuma's group having found the button switch, Aqua wishes to push it and sees what it does. Though Kazuma restrains her having more caution. Megumin happily agrees on Kazuma's caution however presses the button anyway. The space around the group then distorts. Kazuma screams that it was a trap and group dissolves into hysteria as they vanish.

Ainz lost in thought is briefly roused by Albedo. Stating its nothing he allows her to continue her assessment on the state of the Baharuth Empire. Ainz is less concern with the New World politics and senses something amiss. Sitting down, on the Throne of Kings a button appears on the seat. The button is pressed and a spatial distortion envelopes Ainz and the Floor Guardians.

The group finds themselves on the grounds of a school. Demiurge postuales that they are in another world, causing Ainz to have a headache as he had already experienced a similar situation. He is interrupted by Aqua who asks is he knows where they are. Turning to her, Aqua see that he is an undead. Kazuma wonders if he has returned to his own world, but Aqua hurries back to her party pointing out that Ainz is undead and accompanied by various monster. Darkness and Mehumin are particularly thrilled at the prospect of fighting such creatures, despite Kazuma's attempts to think rationally.

Kurt von Rudersdorf then screams that its time for class to begin. Relocating to Class-2, the two groups find themselves in the midst various characters. One in particular, Tanya von Degurechaff wonders to herself what is going on and reflect on her past. Being that she was originally a businessman in an scientifically and ethically moral world, but later was killed and reborn as a girl in a world of magic and war. She remembers that she was forced to participate in a new computation jewel made by Adelheid von Schugel. During the test flight she lost control and was order to press the button for the jewel expansion. However there two buttons when there was only suppose to be one. Unsure of which to press, she presses both and found herself at the school. Looking at her 'classmates' the adventurers and monsters, she wonders if this is the result of Being X.

A new group comes in through the classroom, revealing Natsuki Subaru and his party of friends. Initially excited to be back at school upon seeing the occupants of the classrooms stuns him. Everyone is confused at this situation but nonetheless several members are hopeful for the future.
