NieA_7: Alien & Beginner Waitress Bath

Mayuko has started a new job at a European restaurant where she delivers food (although she tells Chiaki that she's a waitress). After NieA has stuck Chada with a food bill at the restaurant she works at, Chada pays a visit to the restaurant. Mayuko runs a delivery when Genzo shows up looking for her so that he can give her some rice. When NieA come in, she and Chada start to fight again. What else can go wrong for Mayuko?
