Not much is known about Otoha's background, apart from the fact she was home-teached for some time and her parents were reluctant to let her join normal school. There, she was persuaded by Rin, Nodoka and Noriko to transfer into Sensei's class.
Otoha is a calm girl and barely shows emotions around people and tries to remain cool and collected in all situations she's facing. Because of the deal she made with her parents, she is worried about maintaining solid grades, as she believes she finally found some freedom she was hoping for. Just like Rin, she is exceptionally fond of music and often spends weekends mornings in the park, performing.
Just like Rin, Otoha doesn't develop any feelings for Sensei apart from aknowledging his presence and ocassionally talking to him. However, his perversal talks often lead to a quick ending of almost every conversation between them and on some ocassions, Otoha even scolds Sensei for his behavior. However, she can also be friendly with him when they talk over topics of her interest.
Rin and Otoha first met in the park where Otoha was performing, shortly after the first beach trip, and Rin immediatelly developed an enormous crush on Otoha. The two of them quickly bonded over their mutual interest in music, but Otoha described their relationship as "Rin talking in 80 % of cases". Eventually, she noticed how nervously Rin behaves around her or other girls when she is present and realized Rin might've developed feelings for her. However, she wasn't sure if she can handle a relationship with Rin because of her hasteful reactions. Despite that, during the winter beach trip when Rin confessed to her, she accepted and started a relationship with her.
Nodoka is Otoha's long-time friend and a roommate in the dorms. However, her perversal thoughs often drives her away from her in the same manner as from Sensei, especially if these two are talking together. Despite that, they are good friends.
Noriko and Otoha were classmates in the previous school they attended and maintain a friendly relationship even after joining Sensei's class.
