Nodoka Toyohama (豊浜 のどか, Toyohama Nodoka) is one of the main characters of Seishun Buta Yarou wa Bunny Girl Senpai no Yume wo Minai series. She is Mai Sakurajima's younger half-sister and is a member of an idol group named Sweet Bullet.
Nodoka was born after Mai Sakurajima's father remarried another woman. As a child, she went to go meet Mai for the first time during one of Mai's audtions and beamed after Mai mentioned that she wanted a little sister.
After Mai's mother made Mai join a troupe out of spite for her ex-husband and Nodoka's mother, the latter made her own daughter join a troupe as a way to get back at her. Nodoka later developed an inferiority complex towards her half-sister after her mother kept comparing her own success to Mai's. Near the end of summer break during her second year in high school, she ran away to Mai's home after a fight with her parents.
On the morning of September 1, Nodoka and Mai switched bodies as a result of Adolescence Syndrome, which prompted Nodoka to head to Mai's apartment. She showed disgust in response to Sakuta's remarks and questioned how he could be her sister's boyfriend. Mai, in Nodoka's body, soon met up with them and speculated the body switch as a result of Adolescence Syndrome. Inside Mai's apartment, upon being asked if she knew anything that would've caused the body switch, Todoka frantically stated she had no knowledge and questioned how Sakuta and Mai were staying calm in the wake of their current dilemma. Deciding that they would have to live under each other's lives, she and Mai exchange and discuss their agendas for the month.
The next day at the train station, Nodoka was asked by Sakuta if Mai (in Nodoka's body) wouldn't catch the attention of the people around her. She dejectedly replied that despite being an idol, she wasn't that popular. At Minegahara High School, Sakuta noticed the way she spoke was much like Mai's, to which Nodoka revealed that she impersonated her as a kid and looked up to her. At the beach, Nodoka denied Sakuta's suggestion that she wanted to tell Mai that she hated her, but realized that Mai most likely had such an idea as well. Sitting on a bench, Nodoka asked Sakuta if she could sleep at his house, but was interrupted by Mai. Nodoka then went up and revealed to her about her feelings of inferiority towards Mai's own success, before proclaiming that she hated her. Mai claimed ill feelings towards Nodoka as well, but put the blame on their father.
Starting on September 3, Nodoka began life as Mai Sakurajima; from her lonely status at school to modelling for photo-shoots along with being interviewed. However on September 12 during a photo-shoot, the pressure from the trust people placed on Mai Sakurajima became too much for Nodoka to bear and caused her to hyperventilate and collapse. That evening in Mai's apartment, Nodoka asked Sakuta if Mai said anything about her and beamed in pleasant surprise after hearing that Mai had no doubt Nodoka would be able to get a good shot. After learning that she hadn't eaten, Sakuta suggested she take a bath while he makes something for her to eat, which she obliged.
Nodoka and Sakuta watched a horror film featuring Mai in an effort to learn how to be more like her sister. Frightened by a scene in the film, Nodoka asked Sakuta to stay with her while she bathed, but told him to die before he went along with her suggestion to call Mai first.
After a film shoot on September 19, Nodoka bemoaned the fact that it took her twelve takes to make a final cut. Later at a train station with Sakuta, upon being given a ticket to a performance by Sweet Bullet, Nodoka reminisced her first meeting with her sister and announced her intention to get a song where she was the main singer. Walking down the street, the two had a chat about Sakuta's history with his parents when they are confronted by Nodoka's mother, who was looking for her daughter. The two claimed no knowledge of Nodoka's whereabouts and were asked to tell her to hurry back home.
Two days later, Nodoka and Sakuta watched the Sweet Bullet show, but Nodoka became ashamed after witnessing her mother praise Mai (in Nodoka's body) for her performance. She later attempted to drown herself, only to be stopped by Sakuta, who claimed he had proof that Mai would care if something were to happen to her. At Mai's apartment, Sakuta revealed to Nodoka a box filled with letters that Nodoka had written to her sister, indicating that Mai didn't hate her. Nodoka was still unconvinced, claiming that she was a nuisance to her older sister. Once Mai stepped into the room, Nodoka exclaimed that she hated how Mai did everything perfectly and that she couldn't compete with that. In response to Mai's subsequent statement that her mother felt uneasy about whether Nodoka was happy trying to meet her expectations, Nodoka cried that she wanted her mother to compliment her for once. Mai hugged Nodoka, who suggested that she make her happy on her own terms. After spending a brief moment crying uncontrollably, Nodoka was relieved to hear that she didn't have to be exactly like Mai; after proclaiming that she didn't want to be, she and Mai transformed back to their original appearances, much to their joy.
Nodoka had another fight with her mother shortly after, which prompted her to move in to Mai's apartment. She thanked Sakuta for saving her despite the trouble she gave, before stating that she somewhat understood why Mai chose him.
As a child, Nodoka looked up to Mai as a personal idol and hoped to meet her one day, which came true after some time. However, as her mother began measuring her success to Mai's as she got older, Nodoka felt resentment towards her sister and grew an inferiority complex towards her. After learning that Mai had indeed cared about her, the two rekindled their relationship as sisters.
