Rascal Does Not Dream of Santa Claus Episode 1: Puberty Continues

Tomoe Koga shows Sakuta Azusagawa a social media post, a cryptic dream about broken fluorescent lights in a specific classroom. Sakuta dismisses it, teasing Koga about her boyfriend dreams, his nonchalance a shield. He jokes that a "hero of justice" will handle it, unaware he speaks of himself. This lighthearted banter begins to hint at deeper disturbances.

Sakuta walks with Mai Sakurajima at sunset, discussing a former classmate, Akagi Ikumi, and her burgeoning Puberty Syndrome. He mentions a middle school reunion invitation. Mai expresses genuine fear, having seen social media posts about a dream where someone gets stabbed at this very reunion. Sakuta offers a joking remark about stuffing magazines into his pants, a characteristic evasion of true fear.

Sakuta rides a train, his face contemplative as the sun sets over Enoshima, carrying him back to his past. He walks through his old school, observing current students, a ghost in a familiar hall. At the reception desk, he sees Akagi Ikumi's name in the visitor's log, quickening his steps. He finds her alone in classroom 2-1, silhouetted against the setting sun.

Akagi admits her long-held regret to Sakuta, detailing her inaction during his middle school suffering, particularly concerning his sister Kaede. A flashback shows a depressed Sakuta ostracized, while Akagi watches, frozen by social pressure. She speaks of 'tripping' at a crucial moment, unable to intervene, her words laden with years of unspoken guilt. This feeling of powerlessness has clearly haunted her.

Sakuta, ever perceptive, suggests their meeting is a reunion in their "classroom of memories," hinting at something more. He confronts Akagi with his deductions: her unusual friendship, 'poltergeist' activity, and mysterious writings on her skin, all signs of a parallel self. He reveals the final proof, his graduation yearbook, noting a phrase he never wrote, confirming her origin from another world. Akagi is shocked, realizing her secret is fully exposed.

Akagi explains her failed life in her original world, where the other Sakuta was so capable he left her no room to grow. She recounts failing university exams and her wish to escape, finding herself in this world. A flashback shows her first seeing this world's Sakuta, seemingly content, which fueled her desire to prove herself. In this reality, she became a successful volunteer leader, fulfilling her dream because this world's Sakuta was "worse," giving her opportunity.

Sakuta asks why Akagi seems relieved despite being discovered, deducing she wanted someone to see through her facade. He suggests she couldn't forgive herself for abandoning her original reality. Akagi weeps, admitting she was good at 'hide and seek' but felt unseen, losing herself in the role of a substitute. Sakuta reassures her she is still Akagi, grounding her with his blunt honesty. They walk away from the school, and at a train crossing, Akagi reveals a message on her thigh, "Te espero en la reunion," before disappearing as a train passes between them.

As the train clears, Sakuta sees a vision of Mai Sakurajima in a middle school uniform, walking past him. This impossible sight leaves him deeply unsettled. The scene shifts to the sounds of a lively reunion party. Sakuta runs frantically through the city, his urgency palpable, driven by the eerie vision and the mysterious message. He races toward the venue, desperate to prevent whatever is to come.

Sakuta bursts into the reunion, his sudden arrival silencing the room. His former classmates stare, their expressions a mix of surprise and discomfort. Akagi then reveals herself, stepping forward in a sophisticated dress, commanding attention. She announces her own experience with Puberty Syndrome, challenging her disbelieving classmates. She questions their inability to accept the supernatural while dismissing their own cruelties.

A classmate, Rina, lashes out, accusing Akagi of ruining the fun and bringing up the past. Rina claims Puberty Syndrome caused her family trouble, projecting her own discomfort. Akagi deftly turns Rina's hypocrisy against her, pointing out her nervous social media posts. Akagi then addresses the entire class, condemning their past mockery of Sakuta, stating their behavior "ruined his life," and calling them the truly "unwell" ones. They claim it is "too late," but Akagi insists only Sakuta can make that judgment.

Sakuta shatters the escalating tension with a sudden, loud laugh. He declares the entire confrontation a mere "prank," a pre-planned "magic trick." To seal the diversion, he boasts about dating the famous Sakurajima Mai, claiming he is far happier than any of them. With a cheeky exit, he leaves his classmates bewildered and the conflict defused, having sacrificed his own dignity for a fragile peace.

Sakuta walks alone through the night city, his bravado gone, the festive lights of a Christmas market only emphasizing his exhaustion. He finds Akagi Ikumi waiting for him on a bridge, overlooking the city. The quiet night offers a stark contrast to the earlier chaos, setting the stage for their final, intimate conversation.

Akagi explains her true motivation for the confrontation: to show Sakuta he was not wrong, to bridge the gap she felt between them. She confesses her shame at seeing him so confident at university, feeling "pathetic" and "not cool" compared to the idealized version of herself in this world. She admits she was desperate to shed her "hateful, useless past self." Her voice is shaky, raw with years of self-loathing.

Sakuta offers Akagi a simple, profound truth: to live day by day. He tells her to eat breakfast, go to school, attend classes, talk with friends, and sleep. He acknowledges the bad memories will return, but insists the only way forward is to keep waking up and repeating the cycle until the pain fades. His practical, compassionate words bring Akagi a genuine smile and a path toward healing.

The next day, Sakuta and Mai share lunch, their usual playful banter restored, a picture of domestic peace. Sakuta apologizes for bragging about Mai, who teases him in return, their bond reaffirming itself. But their calm is shattered. Akagi suddenly appears, showing Sakuta a message on her hand from the other Sakuta: "Find Touko Kirishima. Mai-san is in danger!" Their expressions turn to alarm as the episode closes on a chilling cliffhanger.
