In this episode, Nano tries on her new uniform and takes pictures with it. Sakamoto asks her why she is so hyper and Nano asks him if she looks like an ordinary girl. He says yes and she is over joyed.
Nano is concerned that the screw on her back will prevent her from making friends and will only make people think she is weird. Her suspicions are some-what confirmed when she enters the class and everyone stares at her shockingly. She resorts to sitting quietly alone for the entire day until Mio and Mia begin talking to her. They invite her to sit with them, but a fight between Mio and Yuko prevents this from occurring.
This fight was AMAZING BTW.
I love this episode because it furthers the plot from the last episode and continues to show that a linear plot is possible and is even very entertaining between these characters. Mio and Yuko become even closer through this encounter, even though it was about a very stupid thing to begin with, and Nano realized that there were people who would accept her. She still however feels that she would be better off without the screw in her back, but Professor refuses to remove it yet again.
