Azz being a Rank 4 (Daleth) demon. Uval then comes in pushing the waitress aside trying to make herself look like the better less rude choice compared to the lower ranked waitress, and asks Azz to a dance. However, Azz ends up choosing the waitress noticing that the latter was showing proper etiquette when she was trying to speak to Azz. While Azz dances with the waitress, he explains that rankings don't matter much to him as he came to respect someone (Iruma) who started at Rank 1, and that said person continued to push forward without ever worrying about his ranking. Azz assures the waitress that she's already showing her worth outside of the demon rankings, which makes her happy.
Following the dance, everyone congratulates Azz and the waitress for the show they put on, even Uval. Azz's words left an impact on the waitress to the point of her wanting to one day be as dignified and graceful as him.
