Mai Sakurajima — Character Biography & Gallery

Mai’s Adolescence Syndrome escalates until people not only fail to notice her but forget that she exists; even her mother no longer recognizes her. Sakuta struggles to stay awake so that he will not lose his memories of her. His declaration of love in front of the school finally breaks through the collective disregard, restoring her place in other people’s perception.

By the time her crisis resolves, Mai has decided to return to acting under a different agency rather than accept the arrangements that caused her hiatus. She takes ownership of the career she still wants, and she and Sakuta begin dating after the school-wide declaration brings her back into view.

Mai’s younger paternal half-sister Nodoka Toyohama has grown up under comparisons with Mai’s success. In the fourth light novel, Adolescence Syndrome causes the two sisters to exchange bodies. Mai must live publicly as Nodoka, while Nodoka is forced to perform the role of her famous sister, exposing anxieties that ordinary conversation had not resolved.

The body-swap crisis makes the sisters confront their difficult relationship rather than merely exchange outward appearances. Their bond becomes warmer, and Nodoka later lives with Mai. The story treats Mai’s fame as something that can inadvertently burden the people close to her, even when Mai never intended that burden.

The Shoko Makinohara storyline confronts Mai with a terrible conflict: Sakuta is drawn toward a fatal traffic accident while trying to save a younger Shoko who needs a heart transplant. In one possible sequence, Mai pushes Sakuta clear of the car and dies in his place. That temporary future would make Mai, rather than Sakuta, the donor of the heart Shoko needs.

This is not Mai’s permanent fate. Sakuta intervenes to prevent the accident, and the story moves toward a revised future in which Mai lives. Her acting career also matters to the resolution: a film featuring Mai helps bring about a heart donor for Shoko. Their continued life together makes clear that the tragic alternative was not the story’s final outcome.

By the ninth volume, Mai graduates from Minegahara High School. Around that transition, Sakuta meets a little girl who looks remarkably like Mai during her child-acting years. The uncanny resemblance belongs to a broader mystery confronting Sakuta and his family; it does not establish that Mai herself has literally become a child.

Mai continues preparing for adult life while sustaining the professional and personal commitments that have defined her. The pressure of leaving school and choosing a future is treated as a meaningful transition rather than a simple epilogue to the library encounter.

During the university arc, Sakuta and Mai attend the same university. Mai is again active in acting, and the two are publicly known to be dating. Her demanding schedule continues to compete with the quiet time she values with him. Official supplementary materials describe her taking a year away from university and beginning first-year study alongside Sakuta afterward.

New Adolescence Syndrome cases involving the students around Sakuta carry the story into a different stage of life. Mai remains central to the stakes even when she is not the person experiencing each case.

In the later university story, the mysterious singer Touko Kirishima becomes linked to warnings that Mai is in danger. At a music festival, Sakuta encounters multiple apparent versions of Mai, while her participation in the performance leads to a public announcement that she is Touko Kirishima. The Japanese publisher explicitly describes that declaration in the fourteenth novel.

The announcement is a dangerous development rather than a straightforward confirmation of Mai’s secret career as an anonymous singer. It coincides with reality becoming unstable and brings Sakuta into the final mystery. Official adaptation materials describe the declaration as the beginning of the world’s apparent rewriting, but the film’s scene-level presentation is supplementary to the light novel.

In the fifteenth and final main light novel, Rascal Does Not Dream of a Dear Friend, the mystery of Touko Kirishima becomes entangled with Miori’s past and Sakuta’s final case of Adolescence Syndrome. Mai’s apparent identification with the singer is only one part of the crisis: Sakuta must decide how to respond when the world he remembers no longer matches the world around him.

In the 2026 film adaptation, the singer whose songs appeared online as Touko is connected to Miori’s lost childhood friend. Miori takes the stage to sing in her friend’s place; Mai, who has been caught in a distorted version of reality, returns to herself. The film later shows Mai and Sakuta together by the shore.

Mai’s professional life does not disappear with the resolution of her first syndrome: she resumes acting and eventually attends university alongside Sakuta. They are still together during the final arc. In the theatrical adaptation’s closing imagery, their time together at the Shichirigahama shore brings the series back to the ordinary encounters that mattered long before the larger mysteries reached their conclusion.
