Description
Mai Sakurajima is a third-year high school student at Minegahara High School and a central figure in the story. She is a nationally recognized actress and model who began her career as a child, gaining fame from a morning drama series at the age of six. Standing 165 cm tall with long black hair that she often adorns with rabbit-themed accessories, she possesses a notable and attractive presence. Her birthday is December 2nd.

In terms of personality, Mai presents a composed and mature exterior, often handling situations with a calm and serious demeanor. She is kind-hearted, polite, and strong-willed, though she also has a playful and teasing side that emerges in her interactions, particularly with Sakuta Azusagawa. While she is generally confident, she can become flustered and reactive to Sakuta's shameless or lewd remarks, which is a running dynamic in their relationship. Despite her fame, she has been somewhat isolated at school, as her celebrity status and frequent absences due to work made it difficult for her to form social groups, leading her to spend much of her time alone.

Mai's primary motivation throughout the narrative is tied to her career and personal identity. She took a hiatus from acting during middle school as a form of rebellion against her mother, who also served as her manager and had pushed her into uncomfortable situations, such as a swimsuit photoshoot without her consent. Deep down, however, Mai still loves acting and wishes to pursue it on her own terms. This internal conflict manifests as Adolescence Syndrome, a supernatural phenomenon where her growing desire to be in a world where nobody knew her causes her existence to become imperceptible to others.

Her role in the story is first established as the primary subject of the "Bunny Girl Senpai" arc, where she is the first person Sakuta helps with Adolescence Syndrome. After they succeed in making her visible again and begin dating, her role evolves into that of a key supporter and partner to Sakuta. She is not merely a damsel in distress; she is an active participant who often helps resolve conflicts. In the Santa Claus narrative, she demonstrates significant insight and agency, using her emotional intelligence to directly confront and dismantle another character's Adolescence Syndrome by speaking harsh truths. Her relationship with Sakuta is defined by their witty, deadpan banter, deep mutual trust, and a willingness to sacrifice for one another.

Key relationships define much of her character arc. Her most significant relationship is with Sakuta Azusagawa, who becomes her boyfriend. He is the only person who could initially see her during her period of invisibility due to his own past trauma with Adolescence Syndrome, and his persistent, unconventional methods of helping her form the basis of their bond. Mai holds a complex relationship with her mother, whose exploitative management style led to Mai's hiatus and subsequent syndrome. She also has a familial connection to Nodoka Toyohama, who is revealed to be her younger half-sister.

Throughout the story, Mai undergoes significant development. She transitions from a girl who is fading from reality due to her desire for anonymity to a public figure who has reclaimed her career on her own terms. Her relationship with Sakuta matures from a tentative connection based on necessity to a profound, committed partnership where both characters actively work to protect each other, even at great personal cost, as seen when she sacrifices her life to save him from a fatal accident in a previous timeline. In the Santa Claus story arc, she further solidifies her role as a decisive problem-solver, directly intervening to neutralize a threat to her relationship and to help cure another's syndrome through sheer force of will and emotional clarity.

Mai does not possess typical superpowers, but her experiences with Adolescence Syndrome grant her unique insights. In the Santa Claus arc, she displays an acute ability to see through the facades of others and understand their true feelings. She wields this understanding not as a weapon but as a tool for resolution, using direct, truthful conversation to break through another person's psychological manipulation and force them to confront their own buried emotions, effectively "curing" them. This ability to perceive and articulate emotional truths becomes a defining strength.
