Ep. 10: Class 2 prepares for the school festival while a monster escapes and threatens their event.

Roswaal announces a school festival requiring a food stand and play, promising rewards, though Ainz notes his past failure during field day. Weiss and Viktoriya manage the food stand, with Weiss enjoying chocolate. Class 2 selects Cinderella, drawing lots for roles: Ram as Cinderella, Rem as the Prince, Aqua as the Fairy Godmother, Shalltear as the stepmother, Darkness and Demiurge as stepsisters, and Ainz, Tanya, Kazuma, and Subaru as horses. Shalltear is furious she did not play the Prince with Ainz as Cinderella, while Naofumi is annoyed to play the Ugly Duckling alone. Meanwhile, Hamsuke and Death Knight report that Destroyer has escaped its burial site. The students discover their arch is destroyed, and Aqua worries about the timeline, but Rem insists they can succeed through teamwork. The teachers decide to continue testing the students despite the danger.
