Personality

Eventually, she is revealed by Ozu that she was used by Kirishima instead as a pawn. She was and still is frequently used by men that approach her, despite her wish to never get involved with Kirishima or Ozu ever again.

Miyama Kirishima
Kirishima and Nao were a couple since high school, but Kirishima dumped her for attending a modelling competition, stating that she is too 'normal' for him. However, even after breaking up, she still approaches him, and Kirishima is not even reluctant to have sexual intercourse with her; although they did not get back together after that. Nao was also willing to use Kirishima for certain reasons like exposing him, however, Kirishima played his cards right and backfired on her instead.

Kento Ozu
Ozu and Nao also were a couple but it's likely after Nao was dumped by Kirishima. Ozu's behavior to her resembles a lot like Kirishima's, and also exposed her directly in front of her that she smoked marijuana in Brooklyn.

Somei Yoshino
Yoshino and Nao met when Nao was in Osaka. Nao sees her as something dangerous, despite Yoshino has yet to done a threat to her. Nao also exposed Kirishima's family background to her since she knows Kirishima as well. She also tried to lure Yoshino to Ozu, since he ordered her to.

Toriashi Shouma
She and Shouma met when he was baited that she was Yoshino by Kirishima. Highly disappointed, Shouma takes Nao with him anyways, and dragged her out of the room. He seems to not wanting her to stay in danger while he fights, and tries to get her to leave.
