At the 9th Floor bar, Yuri Alpha and Narberal Gamma thank Sous-chef for instructing them and address him as "Master," making him flustered. They insist it's the correct title since he's now their instructor. Sous-chef accepts, and they begin their training. He explains the importance of a relaxing atmosphere and clear glasses at a bar. Their first task is to wipe a glass clean, but Yuri attempts to punch it to test durability, stopped by Sous-chef. Narberal uses magic to make herself and the glass invisible, thinking she achieved the goal. The maids find the task unexpectedly challenging, and Éclair Éklair Éklare chuckles at the scene. The episode concludes with one of the maids accidentally breaking a glass, adding a humorous twist to their training. (thetvdb.com)
