Ep. 9: Filo selects The Ugly Duckling for the Class 1 school play after consulting various companions.
Aired on March 11, 2020

Class 1 requests Filo to choose a theme for their upcoming school performance. She seeks input from others, receiving suggestions from Ainz's followers to feature him. Tanya instructs Megumin on precise explosion magic to minimize collateral damage, though she fails to persuade her to shorten the incantation. Mare and Beatrice provide Filo with a fairy tale book, but since she cannot read, she asks Naofumi to read it aloud. Lupusregina offers inappropriate ideas, earning reprimands from Yuri and Narberal. After Narberal insults Tanya's subordinates, Lupusregina proposes The Ugly Duckling. Following the reading by Naofumi, Filo selects this story for the play. Naofumi's praise for Filo subsequently causes Raphtalia to feel jealous.
