In his dorm vignette Vil assigns all of Pomefiore to “carefully curated curriculum” so that they might “reform” themselves and be ready for a visit by an international fashion magazine that is doing a feature on the dorm and the daily lives of its members.
Vil says he will “have to start from the basics” with Epel as his “aesthetic sense is considerably lacking compared to the others” and assigns him a cleaning regime that involves wiping down every window in Pomefiore without magic.
Pomefiore students (and Epel) complain about Vil not suffering along with them and making their lives rough for the fun of it, but then overhear Vil’s plan to stay up late working on his curriculum for the students of the dorm.
Rook observes that it is unlikely that any of them realize the lengths that he is going to and Vil responds, “And they needn’t. I’m not going it because I want them to like me. As housewarden, it is my duty to guide them down the path of refinement.”
This placates Epel and the other students, who decide they were silly to think that Vil doesn’t work and they should trust in his judgment, even if it is harsh, and live up to his expectations for them.
The magazine reporter later says that they can find no flaw in any of Pomefiore’s students and ask Rook and Epel to pose with Vil for a photo, telling Epel that they had been impressed when he had accepted their bags when they arrived, despite how heavy they are. Epel reflects, “Is that why Vil made me clean all those windows? So l’d get stronger?”
When asked about the secret to beauty for Pomefiore students Vil responds, “We are constantly aiming to be the best we can be. I believe THAT is our greatest secret.”
