Rascal Does Not Dream of Bunny Girl Senpai

Sakuta's calm high school days with Mai are disrupted by the sudden appearance of Shoko Makinohara. He realizes there are two Shokos—the middle school girl and the older one who has already touched his life. The revelation begins a cascade of overlapping timelines that will redefine their relationships.

Shoko in middle school is diagnosed with a severe heart disease that urgently requires a transplant to save her life. Sakuta and Mai realize that two versions of Shoko exist, complicating their concern and forcing them to confront a mystery beyond ordinary explanation. The medical crisis tightens the stakes of every choice they make.

Adult Shoko comes from the future after a successful heart transplant and explains the unbelievable truth: her donor was Sakuta, who was brain dead following a Christmas Eve accident. She reveals that she traveled back in time to save him by giving him a second chance at life. The revelation ties their fates to the future of Shoko and Mai.

On Christmas Eve, Sakuta decides to sacrifice himself to spare Shoko's life. Mai, acting to shield him, is struck by a car and dies, becoming Shoko's heart donor. The moment interrupts the original plan of fate and reshapes their relationships forever.

After Mai's death, adult Shoko hints that there might be a way to return to the past and rewrite what happened. She offers guidance and support to help Sakuta navigate the impossible task. The possibility of a second chance gives Sakuta a fragile spark of hope.

With adult Shoko's help, Sakuta travels back to Christmas Eve to change the outcome. He borrows inspiration from Mai and wears a pink rabbit costume at the train station to signal someone who can see him. He meets Tomoe Koga, who becomes the first person able to notice his presence and he asks her to contact his past self.

During the attempt, the past and future selves cannot meet, and the changes ripple across the timeline. Although the immediate crash is avoided and both Sakuta and Mai survive, Shoko loses her heart donor and remains destined to die.

Sakuta and Mai refuse that tragic outcome and vow to find a way to save Shoko without sacrificing their lives. They commit to finding an alternate solution that could preserve Shoko's life while preserving the memories they've built. The choice deepens their bond and sets the stage for new sacrifices.

Sakuta visits the younger Shoko to speak with her and understand the depth of her memories. She reveals that she is aware of the timelines and decides to write a future where she never meets Sakuta or Mai to spare them sorrow. This act shows Shoko's agency in shaping her own fate.

Time rewinds to New Year's in the present day, and Mai stars in a film based on Shoko's story, though she no longer remembers their real life together. The film's success signals a different kind of memory taking hold in the world. The past's echoes begin to blur with the present.

Sakuta and Mai visit a shrine and walk along a beach, and for the first time they glimpse Shoko as a healthy young girl. The moment confirms that the timelines have started to converge in a new, hopeful way. They realize memory pieces are crossing between worlds.

Through memories crossing different timelines, Sakuta and Shoko finally recognize each other. The encounter marks a new beginning where Shoko grows up healthy and Sakuta and Mai can build a future together. The story closes with the possibility of love rekindled in a shared, altered reality.
