Arisu is drawn back into the Borderlands after Usagi is taken there by Ryuji, an academic obsessed with the afterlife who has developed a drug that can temporarily stop a person's heart and send them into Borderland. Usagi, struggling with the trauma of her father's apparent suicide, is lured back by the chance to see him again. Arisu visits Usagi in the hospital, where he learns she is pregnant, and he becomes determined to return to Borderland to rescue her.

Upon entering Borderland, Arisu and Usagi are separated and must each join different groups of players to survive the deadly games. Arisu encounters Ann, a forensic scientist from previous seasons, who provides him with crucial information about the nature of Borderland and the connection between the living world and this purgatory-like realm.

Throughout the season, Arisu and Usagi face a series of nine new games, each testing their physical and mental limits. The games reveal the selfish and cooperative aspects of human nature, forcing the characters to make difficult decisions about trust, sacrifice, and survival. Arisu's leadership and strategic thinking help his group navigate these challenges, while Usagi confronts her emotional vulnerabilities and trauma to protect those she cares about.

As the season progresses, Arisu and Usagi's paths converge again, and they reunite with surviving members from their respective groups. Together, they prepare for the final game, which is revealed to be a confrontation overseen by a mysterious figure who watches over the land between life and death. This final game is a high-stakes battle that will determine their fate and the possibility of returning to the real world.

In the climactic final game, Arisu makes a critical decision to sacrifice himself to ensure Usagi and the others can escape Borderland. His selfless act allows the group to overcome the final challenge, but it comes at the cost of his own life. Usagi, now pregnant and carrying the hope of a new future, is left to carry on and build the family she and Arisu dreamed of.

The season ends with Usagi confronting her past trauma and embracing her resolve to protect her new family, symbolizing a step toward healing and hope beyond the harsh trials of Borderland. The story closes on a note that sets up potential future narratives, including a spin-off exploring the deeper mysteries of the afterlife and Borderland's true nature.

At the end of Alice in Borderland Season 3 (2025), Arisu and Usagi return to the Borderlands to complete the Joker Card Tournaments, signaling a new cycle of challenges ahead.

The ending unfolds scene by scene as follows:

The final episodes focus on Arisu and Usagi confronting the last stages of the Joker Card Tournaments in the Borderlands. After intense games and battles, they succeed in completing the tournament, which is symbolically significant as the Joker card represents unpredictability and the cycle of the games themselves.

The scene then shifts to Arisu's office in the real world, where an earthquake shakes the building. This event is minor in itself but is reported as part of a series of escalating quakes worldwide. The Watchman's earlier comment that "countless others will be arriving soon" implies that the Borderlands are about to receive a new influx of players, hinting at a larger, possibly apocalyptic event looming on the horizon.

The season closes with Arisu and Usagi preparing to return to the Borderlands, suggesting that the cycle of games and survival challenges will continue. This ending leaves the story open-ended, with the characters' futures uncertain but poised for new trials.

In summary, the main characters survive and move on with their lives, each finding a new role or purpose. Arisu and Usagi remain central, returning to the Borderlands to face the next phase of the Joker Card Tournaments. The final moments foreshadow a broader catastrophe and the continuation of the Borderlands' deadly cycle.
