NAOTA NANDABA
A lot of that performance comes from his older brother Tasuku. Tasuku was the baseball star who left for America, the person Mamimi loved, and the standard Naota quietly measures himself against. Naota even carries Tasuku's bat while refusing to swing it. Not trying lets him avoid discovering whether he can live up to the person he has built his brother into.
Then Haruko Haruhara arrives and makes detachment impossible. She opens an N.O. channel through Naota, uses him as a passage for machines and weapons, moves into his house, and becomes another person whose attention he wants even when he knows he should not trust her.
Naota's growth is not that he suddenly becomes mature. It is that he gradually stops using indifference as protection. By the end he can swing the bat, admit what he feels, confront Haruko, and let both her and Atomsk go without pretending none of it mattered.

He is Naota's older brother, the baseball player everyone remembers and the person whose bat Naota carries without swinging. He is also Mamimi's absent boyfriend, now living in America while she remains in Mabase.
That leaves Naota and Mamimi building a relationship around the same missing person for completely different reasons. Naota wants Mamimi to see him as himself. Mamimi keeps calling him Takkun and reaching for the familiarity Tasuku left behind.
Attraction, Manipulation and the Person He Cannot Control
She is exciting, invasive, funny, dangerous and completely unwilling to behave according to the rules Naota uses to keep the rest of his life manageable. He distrusts her and wants her attention at the same time.
Haruko has her own reason to stay close. Naota's N.O. ability makes him useful in her pursuit of Atomsk, and she repeatedly pushes him toward situations he does not understand because she wants access to what can come through him.
The relationship therefore never becomes a clean romance or a clean manipulation.
Episode 4 · Tasuku's Bat Stops Being an Excuse
As long as he never tries, he never has to find out whether he can live up to his brother. The bat lets him remain connected to Tasuku while protecting himself from the comparison at the same time.
Episode 4 finally removes that option. With the falling satellite threatening Mabase, there is nobody else Naota can wait for. He has to swing.
Episode 6 · He Gets the Power She Wanted
Atomsk manifests through Naota, placing the enormous power Haruko has been chasing in the hands of the boy she treated as the route to it.
Naota confronts Haruko carrying that power, tells her that he loves her and then releases Atomsk instead of surrendering him to her. Haruko immediately chooses the chase and follows Atomsk away from Earth.
Ninamori and Performing Maturity
Open →The Class President Is Acting Too
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.
Tasuku Leaves · Naota Fills the Space · The Name Moves Again
She misses Tasuku.
Calling Naota Takkun lets Mamimi preserve some version of the relationship she lost, but it leaves Naota trapped between wanting her affection and knowing it is partly directed through him toward somebody else.
When Mamimi later gives the same name to another creature, the pattern becomes impossible to ignore.
