Newlyweds Takashi and Machiko awaken in the elegant Quindecim bar with no memory of how they arrived. Bartender Decim tells them they cannot leave until they play a game staking their lives. A roulette selects darts, and each section of the board is linked to an organ in the other player's body, making every hit cause real pain. As the match proceeds, fragments of their lives return. Takashi remembers suspecting Machiko of having an affair and recalls the argument that caused their fatal car crash. Machiko denies betraying him, but his jealousy turns the game into an attempt to punish her. After Takashi wins, Decim reveals that both guests were already dead and that the game existed to expose their souls for judgment. Machiko then claims she married only for money and that her unborn child belonged to another man. Takashi attacks her until Decim restrains him with puppet-like threads. They depart in separate elevators displaying different masks: Takashi is sent toward reincarnation and Machiko toward the void. The decision appears straightforward, yet Machiko's final expression and contradictory statements leave open whether she deliberately lied to release her jealous husband from guilt.

A nameless black-haired woman awakens without memories and is escorted by Nona to Quindecim. Nona assigns her as Decim's assistant and explains that the bar receives pairs of people who died at the same time. Arbiters restore their memories gradually, place them under extreme pressure through games, and decide whether each soul will be reincarnated or sent into the void. The woman observes Takashi and Machiko's darts match from behind the scenes, seeing both the mechanisms that inflict pain and Decim's detached interpretation of their behavior. After the couple leaves, she challenges his judgment. She believes Machiko's affair was a single regretted mistake and that the baby was probably Takashi's. In her reading, Machiko lied at the end so that Takashi could reject her and enter the next life without remaining consumed by jealousy or responsibility for their deaths. Decim is surprised that he may have mistaken a self-sacrificing performance for cruelty and apologizes, though the judgment cannot be reversed. The assistant's empathy introduces a perspective absent from the formal system: actions shown under artificial terror may not reveal a simple moral essence. Elsewhere, Nona reads a picture book called Chavvot, which appears connected to the woman's missing identity.

Two teenagers arrive at Quindecim and are assigned a bowling match. Rather than becoming hostile, the pair quickly enjoy one another's company. The boy remembers that he is college student Shigeru Miura. The girl identifies herself as Chisato Miyazaki, a childhood friend who moved away years earlier. Their restored memories suggest that they recently met again by chance and died together in a bus accident. Shigeru recognizes the affection he once had for Chisato and, after winning, asks to use their remaining time for a brief date in the bar. Decim and his assistant quietly provide food and space while the two reconnect without fear or competition. Before entering the elevators, the girl recovers the truth she concealed even from herself: she is actually Mai Takada, another childhood friend who underwent extensive cosmetic surgery to resemble Chisato because she wanted Shigeru to notice her. Shigeru never learns the full revelation, but their final exchange remains sincere. Decim sends both souls to reincarnation. The gentle judgment demonstrates that the games do not always produce violence; under pressure, some guests reveal kindness, regret, and a wish to spend their last moments making another person happy.

Teenager Yousuke Tateishi and television celebrity Misaki Tachibana arrive at Quindecim. Misaki assumes the bar is part of a hidden-camera program and encourages Yousuke to perform for the audience. Their game is an arcade fighter whose characters resemble them. During the first round, Misaki remembers abusive partners and the struggle to support her children through a public career. Yousuke recalls an emotionally distant childhood and a stepmother whose attempts to connect he rejected. Decim manipulates the controls to intensify frustration, explaining that an arbiter must draw out the darkness of each soul. Once Misaki realizes they may die if they lose, fear overtakes her polished persona. She physically strikes Yousuke unconscious and immediately regrets it, but Decim forces the match to continue. Their final memories reveal that Yousuke died by suicide after withdrawing from his family, while Misaki was killed by an assistant she had mistreated in anger. Yousuke recognizes too late that his stepmother cared for him. Decim sends him to reincarnation and Misaki to the void. The assistant is disturbed by how deliberately Decim engineered the violence, questioning whether desperation created by the test can fairly define a person's entire life.

The black-haired assistant repeatedly dreams of a boy named Jimmy and a deaf girl named Chavvot, matching an image Nona asks Decim to display behind the bar. Two unusual guests then arrive: an adult man who claims to remember Quindecim and a silent young boy. Decim focuses on the man's apparent violation of the rules, especially when he becomes violent, and restrains him. The boy suddenly puts both Decim and the assistant to sleep and reveals himself as Ginti, another arbiter. The adult is not a human soul at all but a mannequin implanted with memories. Nona designed the encounter to test Decim, who failed to notice that the supposed child had no memories because the more dramatic guest captured his attention. Ginti criticizes Decim for keeping the unjudged assistant, whose own death should have sent her through a game. Their confrontation becomes physical until Nona stops them. She is deliberately allowing the woman to work beside Decim as part of a larger experiment involving arbiters and human emotion. Nona continues studying the same picture book, suggesting that the forgotten story may unlock the woman's identity and determine why she cannot yet be processed like an ordinary guest.

At Ginti's traditional-style bar, enthusiastic schoolgirl Mayu Arita is paired with Harada, a singer from her favorite idol group, C.H.A. Ginti selects Twister and quickly loses patience with Mayu's excitement. He alters the floor so different spaces burn, freeze, or otherwise punish the players, then suspends them above apparent spikes for a sudden-death finish. Harada initially considers pushing Mayu to save himself, haunted by memories of casually abandoning a former girlfriend who later died by suicide. Mayu chooses to release her grip instead, preferring that her idol survive. Harada catches her out of guilt and genuine concern, but she lets go to protect him. The spikes prove to be rubber, exposing rather than completing the sacrifice. Their memories return: Mayu died in a mundane bathroom accident after slipping on soap, while Harada was murdered by the sister of the woman whose death he helped precipitate. Freed from the game, Mayu changes into a kimono and Harada begins responding to her as a person rather than a fan. They perform an impromptu concert for the arbiter staff. Ginti postpones their judgment, irritated and intrigued by a bond that developed despite his attempt to provoke selfishness.

The black-haired woman discovers the Chavvot picture book and recognizes its silent girl and smiling boy from her dreams. The connection restores her awareness that she is dead, though her name and life remain incomplete. Decim explains that the book belonged to Quin, Quindecim's former arbiter, who now works in the information bureau. Flashbacks show Decim during training, observing one of Quin's games. When Nona asks why he refuses to manipulate the contestants with the control device, he says that people who lived full lives deserve respect. Over drinks, Quin confirms that Decim appears to experience emotions supposedly absent from arbiters. Decim then shows his assistant a private collection of mannequins dressed as former guests. He reconstructs them so that the people he judges will not be completely discarded and forgotten after their souls depart. The practice is unsettling but also reveals attachment beneath his impassive manner. Nona prepares another experiment, arranging for two specially selected souls with violent memories to reach Quindecim. While the assistant moves closer to recovering her identity, Decim's capacity for empathy is about to be tested by a case designed to challenge whether judgment can remain objective when both guests have killed.

Nona sends Decim two men whose memories indicate that at least one is a murderer. Shimada is a young man devoted to raising his younger sister Sae, while Tatsumi is a police detective whose wife was killed. Shimada finds a bloodstained knife among his belongings but cannot remember using it. The pair play air hockey, initially cooperating in hopes of discovering an exit. Shimada remembers learning that Sae had been assaulted and tracking the attacker. Tatsumi recalls hunting the man who murdered his wife and adopting a personal philosophy of judging criminals outside the law. Decim changes the table so that each puck represents an organ; scoring causes the opponent pain in the corresponding body part. The assistant asks to view the full memories supplied to Decim and learns that both guests committed murder before dying. That knowledge undermines the initial assumption that the game will separate a criminal from an innocent person. As Shimada and Tatsumi remember more of their final night, their cases begin to intersect. Decim continues the test, believing extreme suffering will reveal which soul deserves condemnation, while his assistant fears that the method is manufacturing vengeance rather than uncovering a fixed truth.

Shimada killed the man who assaulted Sae, then encountered Tatsumi and stabbed him after deciding the detective had been an accomplice. Tatsumi had indeed watched the assault without intervening, claiming he needed enough evidence before passing judgment. He had already murdered his wife's killer and came to view observing human evil as justification for his own vigilantism. Tatsumi fatally wounded Shimada during their confrontation, and both died soon afterward. Decim gives Shimada a final opportunity to punish Tatsumi by stabbing the pucks linked to his organs. The assistant argues that memories selected and presented by an arbiter cannot capture an entire person. She reminds Shimada that Sae wanted her gentle brother back, not another act of revenge. Tatsumi deliberately provokes him, insisting that people reveal their essence through darkness. Shimada succumbs and repeatedly attacks the organ pucks until Tatsumi's representation dies. The assistant is devastated, while Decim is shaken by her claim that his process ignores how fear, grief, and manipulation shape behavior. The elevator masks imply that both men are sent to the void. Rather than producing moral clarity, the test destroys Shimada's last chance to step away from the vengeance that had already killed him.

After Shimada and Tatsumi's judgment, Decim doubts whether his games can fairly evaluate human souls. Nona reminds him that the black-haired assistant must also be judged before her memories deteriorate and her body becomes an empty mannequin. Decim refuses to receive her life as a prepared information package, choosing instead to learn through direct interaction. Nona sends Sachiko Uemura, an elderly storybook illustrator, to Quindecim. Decim, the assistant, and Sachiko play Old Maid with cards decorated by images important to each participant. Sachiko sees a character she once imagined but never published and calmly deduces that she has died. She does not demand the details, expressing gratitude that her art exists somewhere beyond her life. Other cards depict Jimmy and Chavvot. Sachiko explains the story's emotional meaning, allowing the assistant to remember reading it as a child and finally recover her name: Chiyuki. Sachiko completes the game peacefully and is sent to reincarnation. Meanwhile, Oculus, the highest-ranking observer, extracts elevator attendant Clavis's memories and learns that Nona is cultivating human emotion in Decim. Nona asks Quin to retrieve Chiyuki's full memories, preparing a final judgment that may test not only Chiyuki's soul but the rules governing arbiters themselves.

Ginti still holds Mayu and the unconscious Harada. He offers Mayu a cruel exchange: Harada can be spared from the void if she chooses another human soul to take his place. Faced with a stranger's mannequin, Mayu struggles between devotion to her idol and the knowledge that the substitute was also loved by someone. At Quindecim, Decim invites Chiyuki to skate on a recreated ice rink because the activity dominates her recovered memories. As she performs, Chiyuki recalls being a dedicated competitive skater until a severe knee injury ended her career. Losing the identity around which she had built her life, she withdrew from family and eventually died by suicide. After a final drink, Decim puts her to sleep and asks Quin for the remaining memories, ready to complete her judgment. Mayu ultimately refuses to condemn another person and chooses to share Harada's destination. As their forms begin turning into mannequins, Harada wakes long enough to embrace her before both enter the void. Mayu's choice is selfless, yet the result raises further doubt about Ginti's judgment and the system's rigid outcomes. Decim, now carrying Chiyuki's history, prepares a different test centered on her regret and desire to live.

Oculus confronts Nona after learning that she has encouraged emotions in Decim, insisting that arbiters are only dummies and must judge without understanding human suffering. Decim brings Chiyuki into a reconstruction of her family home. She sees her mother still grieving and realizes that her suicide did not end pain but transferred it to someone who loved her. Decim offers what appears to be a return to life if Chiyuki presses a button that sacrifices another person's soul. Desperate to comfort her mother, she nearly accepts. Memories of the guests she met at Quindecim stop her: each condemned stranger also had relationships, grief, and people who might miss them. Chiyuki refuses to purchase her life with an unknown death. Decim reveals that the offer was her final test. Experiencing her anguish through the human emotions Nona placed within him, he breaks down and apologizes for arbiters who judge pain they cannot feel. Chiyuki comforts him and departs for reincarnation while Decim attempts an awkward smile. Nona argues that genuine understanding is essential to judgment, though Oculus remains resistant. When new guests arrive, he welcomes them with a faint smile, permanently changed by the person he was assigned to evaluate.
