— Mai Sakurajima to Sakuta
Mai Sakurajima (桜島 麻衣, Sakurajima Mai) is the main female protagonist of the Seishun Buta Yarou wa Bunny Girl Senpai no Yume wo Minai series. She is a notable actress and model, who is also a third year Minegahara High School, the same school as Sakuta Azusagawa.
Mai is an attractive individual with a slender, well defined body. She has long, black hair, some of which is held in a bunny-shaped barrette.
In her bunny costume, she wears bright black high heels and wraps her long slender legs that in translucent black stockings. Similar to a black leotard, the outfit highlighted the lines of her body, while the chest made a firm, modest valley. White cuffs accented her wrists and her neck was adorned by a black bowtie.
Mai is a polite but serious individual, especially around Sakuta Azusagawa. She usually responds to Sakuta's openly lewd remarks about her by pinching him or stepping on his foot, but can also be flustered just as easily.
Before her invisibility was subdued by Sakuta, she harbored deep anxiety over the possibility that she could be forgotten entirely. She was also quite sensitive over the topic of her hiatus, as she still harbored bitter feelings over the circumstances which caused them; these feelings have now subsided since she starting acting at another agency.
All in all, although she can be quite sensitive, Mai is a nice and kind individual. Notable examples include when Mai denounced the hospitalization incident as false for Sakuta's sake, and when she gave Kaede a dress both as a gift and to at least spark interest in returning to the outside world.
Mai found early fame as a model for television, magazines, and books, due to the fact that her mother ran a photographing agency. While she did enjoy her job as a model in the show business, after being forced to participate in a swimsuit photo shoot by her mother in her third year of middle school, Mai realized she was simply used as a tool to make her mother easy money and took a hiatus from acting as a way to get back at her. Unbeknownst to Mai, the effects of Adolescence Syndrome caused her existence to become unnoticed by other people, something that she would soon discover.
Two years and several months since beginning her hiatus, Mai went to a library wearing a bunny costume to see if anyone would notice her. She then came across a boy named Sakuta Azusagawa, who was the only person in the building who was able to see her. After introducing themselves however, Mai sternly warned Sakuta to forget about her.
The next day, she was seen walking to school by Sakuta and his friend Yuuma Kunimi. After school in a train station, Mai overheard Sakuta scaring a teenage boy from taking a picture of her and thanked him for it. She did add that she was used to such situations, but confirmed Sakuta's subsequent guess that they still wore her down. The two boarded the train, where Mai becomes flustered after Sakuta mentioned how the bunny suit she wore made it impossible to forget about her. After a brief conversation about Sakuta's involvement in the "hospitalization incident" (which he confirmed that he had no involvement), Mai told him about her history as an actress; she loved the job, but it gradually became stressful to the point that she wanted to be in a world where nobody knew who she was. The two leave the train at Fujisawa station, where she went on to add that she started to notice that at the beginning of a 4-day weekend, no one was able to see or hear her, save for some people at Fujisawa; she would then go around in a bunny suit to see if anyone else would notice her. Mai then attempted to order a custard bun, but her invisibility forced her to let Sakuta do that instead. The latter suggested that her invisibility may have resulted from Adolescence Syndrome, which Mai dismissed that as an urban legend. To prove its existence, Mai was invited to Sakuta's home to see the three scars on his chest and to hear the abnormal circumstances that caused them, while also introducing herself to his sister Kaede Azusagawa. Mai angrily told him to mind his own business after being suggested to return to show-biz, before storming out of the house. However, she was later found by Sakuta outside his apartment for some food and more importantly, to tell him that more people are unable to see her.
The next day, Mai and Sakuta were shopping at the market, where she demonstrated that whatever she held turned invisible with her. She was asked by Sakuta to hold hands with him to see if he would turn invisible as well; she was briefly bothered after hearing Sakuta bluntly admit he had lewd thoughts, but flustered him by holding him even tighter in return. However, she ceased once she remembered they had a fight earlier.
While walking home, Sakuta suggested that she return to acting, but Mai once again told him to mind his own business and that he didn't know anything. Sakuta revealed that he knew the circumstances which drove her to go on hiatus and added that Mai's decision was absurd. Provoked and in tears, Mai slapped Sakuta and bemoaned that she was a mere middle-school student forced to wear a swimsuit just so she could make money for her mother. Sakuta responded that was all the more reason to return to show business and encouraged her not to hold herself back if she wanted to, which allowed Mai to regain her composure. Mai then learned that Sakuta had received his information about her from Fumika Nanjo in exchange for a photo of his chest. Briefly angered that he risked his sister and himself being hounded by the media, Mai phoned Fumika to tell her not to release the photos of Sakuta's scars in exchange for a scoop from herself and concluded that she would return to show business, but from a different agency than her mother's. Mai then admitted to Sakuta that he was right about her wanting to return to the world of show-biz and that she kept lying to herself about those feelings; she revealed that was why she sat in front of his house. Before the two entered their respective apartments, Mai proposed they spend some time with each other at 2:30 the following weekend.
Unfortunately on that day, Mai ended up having to wait an hour and thirty eight minutes more for Sakuta to arrive to the train station. She is mildly annoyed after Sakuta complained that she didn't wear a miniskirt, but pleasantly reacted after he commented that her outfit was nonetheless cute. On the train, Mai asked Sakuta why he cared about her, to which the latter replied that it being in trouble without anyone to rely on is difficult. She then listened to Sakuta tell his story about how one person helped him deal with what was happening to his sister and that he wanted to be to Mai like how the person was to him. However, Mai was able to deduce that the person was a woman, and got off the train, which forced Sakuta to follow her. The two then arrived at Shichirigahama Beach, where Mai learned the person's name was Shoko Makinohara, and was bothered by the fact that Sakuta used to have a crush on her. She then revealed that the beach was where she planned to talk with her mother before leaving for another agency and told Sakuta they would resume their date afterwards. To their shock, her mother did not notice her presence and walked right past her, and was subsequently unable to recollect any knowledge of having a daughter, much less a person named Mai. Distraught and near tears, Mai stopped Sakuta from protesting any further. Later at Fujisawa Station, Sakuta suggested they head to a distant town to see if anyone would see her. She questioned it by asking if any good would come from learning that nobody but Sakuta would see her, but decided to continue their date after hearing that at least he would be with her while they go. On the train, Mai asked if Sakuta remembered her and then listened to him tell her that she had a twisted personality and was never honest. Mai questioned that, and Sakuta replied that she was trying to hide her anxiety. Sakuta bluntly told Mai that he wanted to hold her hand, which Mai eventually obliged to.
At Ogaki, Mai and Sakuta decided to stay at a hotel for the night. The former stated that she would take a bath and made signs for Sakuta to leave the room, but was annoyed enough by his blunt teasing to shower regardless. Once she finished bathing, she and Sakuta went to go buy her some underwear at a convenience store. Mai asked if he would ever forget her, and Sakuta assured that he wouldn't. When the two went to bed, Mai asked Sakuta what he would do if she were trembling and crying over the fact that she didn't want to disappear, to which he replied that he would comfort her. She invited Sakuta to kiss her, which he refused. Mai called him an idiot and proclaimed he missed his last chance to steal her first kiss, but nonetheless thanked him for not giving up on her.
After heading back to school with Sakuta, Mai was shaken after discovering that not even the students could see her, save for Sakuta. A few days pass during exam week, and it did not take her long to figure out that Sakuta had not been sleeping since then so that he wouldn't forget about her. During a study session with him, Mai put Sakuta to sleep by sneaking a few sleeping pills into his coffee. As he tried in vain to stay awake, Mai apologized, but acknowledged his efforts and sincerely thanked him for everything.
After hearing Sakuta's loud confession of love in front of the school, Mai told Sakuta that he was being a public nuisance and tearfully slapped him for breaking his promise that he wouldn't forget her. She stepped on his foot to make him say that he loved her, but pressed harder to force out that he loved her very much. Wanting to avoid the suspension bridge effect, she told Sakuta to repeat what he said a month from now. The latter replied that he'd rather say it every day, to which Mai responded that he had to do so for a whole month. As she was now visible, Mai then loudly denounced the "hospitalization incident" as nothing but nonsense. Sakuta bemoaned the fact that they would be lectured, but Mai reassured him by stating that she would be lectured along with him.
On June 27 at lunch break, Sakuta bluntly told Mai that he loved her and asked her to go on a date with him, to which Mai replied that hearing that for an entire month did not make her heart race anymore. Mai announced she got a part in a drama that would start on July, which had a kiss scene; she disclosed that she had shared her first kiss with Sakuta, but was disappointed to learn that Sakuta was unable to remember it (as it was during the time he forgot her existence). She offered to do it again, but tricked him into kissing a piece of lunch in her chopsticks, and teased him for it. In response, Sakuta disturbed her by suggesting her apparent turn-off made him want to fall out of love. Her face now red, Mai timidly accepted his invitation.
Unbeknownst to Mai, time had looped in an elicited future by Tomoe Koga. On the second June 27 at lunch, Mai repeated her interaction with Sakuta, but the latter flustered her by suggesting he find a new romance. With the same red face, she accepts his invitation, but adds that his method was quite cheeky.
On the third occurrence of June 27, Mai discovered Sakuta in an obscene position with Tomoe. This clearly angered her, as before Sakuta could explain himself, Mai sternly told him not to speak with her. Nevertheless, Mai eventually asked for an explanation on the night of June 27, and once Sakuta told her of the circumstances, she sympathized with Tomoe, stating that it was tough being a girl in high school. Once Sakuta explained that Tomoe's call for help reminded him of his sister, Mai decided to let him off the hook for the time being, but added that he needed to show enough faith to be exempt. After kicking Sakuta in response to his blatant advances, she informed him that starting tomorrow, she would be filming in Kagoshima for a week. She then gave Sakuta a pink dress she bought for Kaede; the latter tried it on, and Mai remarked that she looked cute. Mai approved Kaede's request to call her "Mai-san", and in return, she decided to call her "Kaede-chan".
On July 7, Mai spectated Sakuta knock down and humiliate Yosuke Maezawa at the train station after the latter slandered Tomoe.
On July 10, Mai studied with Sakuta for the upcoming exams; seeing that Sakuta was unmotivated, Mai offered to tutor him in her bunny outfit. The two then had a brief conversation about the fight at the train station. In response to Mai's request to humor her, Sakuta said that he loved her. Mai pinched his cheek and told him not to openly cheat, as he was still acting as Tomoe's boyfriend.
Once Tomoe ended her simulated future and reset time back to June 27, Mai and Sakuta repeated their interactions during lunch as they did in the second time loop. However, when Sakuta asked how Mai felt about him, she made him look in another direction and kissed his cheek. Sakuta openly wished it was mouth-to-mouth, prompting Mai to step on his foot. The couple would then repeat their interactions like how they were in the simulated future, save for spectating Sakuta and Maezawa's fight.
After telling her manager that she was at her boyfriends's house, her manager later informed her that she couldn't make have any more public dates with her boyfriend, prompting to break the news to Sakuta. After she walked home with him, she shared a kiss with Sakuta and teased him before entering the building.
On the morning of September 1, Mai was shocked to discover that she was living in the body of her half-sister Nodoka Toyohama. At her apartment, Mai speculated the cause to be Adolescence Syndrome and told Nodoka (in her body) that they would have to live each other's lives for the time being, before exchanging her agenda for the month with Nodoka's. Starting from September 3, Mai participated in dance practices with Sweet Bullet as well as their public performances.
On September 12, Mai met up with Sakuta while going a for a jog and learned that as a result of the pressure of being Mai Sakurajima, Nodoka had collapsed during her photo shoot. That evening, Mai handed Sakuta a spare key to her apartment, but directed him not to open the cabinets in a certain room. A few days after, Mai handed Sakuta tickets to the next Sweet Bullet performance.
On September 21, Mai performed with Sweet Bullet and it was announced that she would be the featured singer on their next single, which earned praise from Nodoka's mother. Upon discovering at her apartment that Nodoka (who had found her box of letters thanks to Sakuta) was upset over that praise, she explained that she collected her letters to get through the stress of work and encouraged her to make her mom proud on her own terms. After spending a brief moment hugging a crying Nodoka, the sisters reverted to their original appearances.
At her apartment, Mai showed Sakuta on her phone a picture of him walking with Nodoka (in Mai's body), which indicated that their relationship went public. To deescalate the situation with the media, Mai credited her boyfriend as the catalyst behind her return to acting and asked that his privacy not be invaded.
When walking home with Sakuta on October 15, Mai suggested that she was in love with Sakuta more than he thought, before parting ways with him. The following day, Mai was summoned to the science room by Rio, where she permitted Sakuta to follow up with a planned meeting with the older Shoko Makinohara. After school, the couple came across Kotomi Kano, a childhood friend of Kaede; realizing how important it was for him to talk with Kotomi, Mai volunteered to meet Shoko at Shichirigahama Beach instead. Once Sakuta met up with her near sunset, he decided there was no telling if she would ever come and wrote on the sand that he already had a girlfriend, which Mai pleasantly reacted to. At Sakuta's home, Mai helped Kaede reach one of her goals for the year by helping Kaede answer her phone call. On October 19, Mai brought numerous clothing she wore from magazine shoots for Kaede to try on.
On November 10, Mai along with Nodoka went to accompany Sakuta and Kaede at Shichirigahama Beach. After watching Kaede fail to remember Kotomi upon meeting her, Sakuta told Mai and Nodoka that she had no memories of her.
- Main article: Adolescence Syndrome
Mai's effect was that she turned invisible and that others began to forget her. As a result of wanting to be unseen by the public, Mai's existence slowly began to fade away. This effect was subdued once Sakuta publicly confessed his love for Mai in front of the school; effectively forcing the students to acknowledge her existence.
For supernatural reasons, Sakuta is one of the people that can see and remember Mai. Due to his own traumatic past with Adolescence Syndrome, he is the one of the only individuals who can relate to and sympathize with her, and in turn Mai holds a special affection for him as someone she can depend on, such as when she credited him as the influence behind her return to show business during a press conference. While she recognizes that Sakuta will not cheat on her, such as with Tomoe Koga when he pretended to be her boyfriend, she is not surprised that due to his kind nature, he is willing to go great lengths for people he cares about. She is aware of Sakuta's sarcastic and joking nature and often plays along with it.
Having heard about her past from Sakuta, Mai acts very gentle towards her. Kaede does eventually open up to her after Mai gives her some new clothes. Mai is very considerate towards Kaede, such as realizing that her cell phone ringing had upset her and proceeded to answer it in another room.
