In the manga as well as the anime, Okada appears as a consistent group of Tomoko's classmates. In the manga, she is revealed as a close friend of Hina Nemoto to the extent that she becomes upset when she learns that Hina did not confess her dream to become a voice actress to her.
As depicted in both the manga and anime, Okada seems generally pleasant. The manga reveals that she is a close friend to Hina, and she feels hurt when she believes Hina will not confide in her. She can prove outspoken and righteous: she intervenes when she believes Yoshida is bullying Tomoko, becomes upset when she thinks Hina is entering a dangerous industry, and is looked to to step in when Kotomi picks a fight with Yoshida. She similarly feels embarrassed and sad when she feels she has hurt someone and will carry this guilt until she has the opportunity to apologize. She apologizes directly to Yuri for misunderstanding the bullying incident and treats Tomoko and Hina to lunch to apologize for her behavior during the class trip to the amusement park.
She enjoys sports, having played basketball in middle school, takes PE seriously, and makes sports references.
Okada has long blond colored hair in the anime and light-brown colored hair in the manga colored panels that reaches her shoulder. She ties a part of her hair high on her head with a pink band that makes her hairstyle resemble a pineapple. She wears the female student's standard uniform.

Okada and Tomoko initially do not have much of a relationship beyond being classmates. However, Chapter 129 reveals that Okada was jealous of Tomoko when she believed that Hina told Tomoko that she wants to become a voice actress rather than her, her "best friend." For her part, Tomoko inwardly refers to her as "Forehead/Beetle Brow (凸・デコ・deko)." In Chapter 133, she asks to buy Tomoko and Hina lunch as an apology for her behavior during their school trip. During their lunch, she seems genuinely interested in Tomoko. She notices that Tomoko and Kotomi behave similarly and suspects, then insists despite their objections, that they must be friends. In Chapter 139 she visits "Moringa University (森永大学 • Moringa Daigaku)" with Tomoko and Hina.
Okada and Hina Nemoto are close friends and have been in the same class since first year. She has a falling out with Hina which is explained as they reconcile in Chapter 129: Okada felt that Hina did not trust her when she learned that Tomoko knew of Hina's dream to become a voice actress. For her part, Hina felt that Okada started to ignore her when Okada learned of her dream. Hina views Okada as more innocent than she is, partly due to Okada's reaction to learning that as a voice actress Hina could voice eroge. Hina tries to shock Okada again when they visit a university with Tomoko, only to become more shocked herself. In Chapter 148 she begins to suspect that Hina acts strangely around Tomoko.
Kiyota is a classmate, close friend, and has been depicted with her and Hina frequently. When she makes up with Hina, she texts him to apologize to him as well.
