ERI NINAMORI SPOILER!
She does not.
Ninamori's father is the mayor of Mabase, and when his affair and the possibility of her parents' divorce become public gossip, she responds by trying even harder to control how other people see her. She hides the fact that she needs corrective lenses by wearing contacts and even rigs the class vote so she can take the role she wants in the school play opposite Naota.
The pressure finally becomes impossible to keep separate from everything else happening around her. After contact with Naota transfers the strange growth associated with his N.O. channel to her, a Medical Mechanica machine begins emerging through Ninamori instead.
What makes her episode work is that the robot is almost secondary to what Naota discovers first: Ninamori is not naturally calm or mature. She is another twelve-year-old who has simply become very good at hiding when things hurt.

Episode 3 dismantles that image. Her father's scandal is tearing apart her family, she manipulates the class play vote to get what she wants, and the glasses she normally hides become another reminder that the version of Ninamori everyone sees is carefully managed.
Naota catches her in that contradiction because he is doing his own version of the same thing.

The sexual and puberty imagery is hard to miss: sudden growths, embarrassment, bodies changing without permission and other people becoming extremely interested in what is happening.
