Plot[]

After returning from the Borderlands, Arisu has no memories of what happened there. He is questioned by a team of afterlife researchers, including Ryuji, who tries to confirm whether Arisu remembers the mysterious world described by other survivors. Arisu recalls only fragments, such as a red light, a public restroom, and fireworks, but when pressed further, he remembers a journey to a distant land. After the interview, he leaves with Ryuji and meets Usagi, who is waiting for him outside.

The next day, Ann visits Arisu at work and reveals that they once survived another world together. Her vague recollections convince Arisu that something deeper is hidden beneath his missing memories. Later, Usagi calls him in tears and disappears without explanation. At the police station, officers suggest she might be having an affair with Ryuji, as the two were last seen together at a hotel. Determined to find her, Arisu goes to the university, only to learn that Ryuji is also missing. His office is filled with research on the afterlife, including a recorded interview with Usagi.

Meanwhile, Ryuji receives information about a secret organization disguised as a support group but rumored to hold dangerous "seminars". He meets an informant and secures an invitation, intrigued by their talk of people playing deadly "games". At the seminar venue, Ryuji is forced to participate in a real-world game called "Old Maid", where losing costs participants their lives. Everyone except Ryuji, he wins the game and meets Banda as a reward.

After Usagi and Ryuji are found in a coma, the police suspect a murder-suicide linked to the organization. Arisu believes Usagi was abducted and learns that Ryuji had been attending strange seminars. Banda approaches Arisu and tempts him to return to the "beautiful world", leaving behind a Joker card. Desperate to save Usagi, who is pregnant and has a weak pulse, Arisu turns to Ann for help. She explains that the human heart can stop for two minutes before death, then injects him with a drug.

Arisu first assumes the plan failed but then he looks around and realizes that everyone is gone, he is in an empty city once again. Following the instructions on a noticeboard, he heads to a game venue, a summer festival near a shrine, and crosses its threshold, unknowingly becoming the final participant as the next deadly challenge is about to begin.
