The Garden of Sinners: Oblivion Recording

Azaka Kokutou opens the film by introducing herself and explaining how she plans to win Mikiya Kokutou as her lover, even as a dangerous rival looms in the form of Shiki Ryougi. The story then shifts to winter break at the Reien Academy, where the two women are drawn together to investigate a troubling pattern: fairsies that steal memories from students and a suspicious suicide attempt by Kaori. From the outset, the atmosphere is tense, as Azaka views Shiki as a potential threat to her romance with Mikiya, while Shiki remains cool and observant, focused on the mystery before them.

As they walk the school grounds, Shiki Ryougi spots a fairy and pursues it, while Azaka remains oblivious to these magical visitors and is suddenly attacked by an unseen assailant who steals her memory. The investigation reveals that a powerful magus is using fairies to erase memories related to Kaori’s suicide attempt, and the school keeps a written record of the events, suggesting a deeper conspiracy behind the tragedy. The two women press on, trying to piece together what happened, even as Azaka’s sense of reality begins to fray. The stakes rise when it becomes clear that Kaori’s memory—and the truth of her death—are at the center of the disturbance, and that someone within the academy is manipulating what everyone remembers.

Azaka ventures into the old building to confront the truth about Kaori’s suicide, and there she encounters Ouji, who asks Azaka to pray with her in the chapel. Ouji reveals herself as the one who uses the fairies to erase memories, claiming she was friends with Kaori and desires to protect Kaori’s reputation from being tainted by the scandal. Ouji’s plan is fueled by a desire to punish the other students who allegedly covered up Kaori’s death after Hideo Hayama, the former teacher, allegedly forced Kaori into a relationship that led to her tragedy. Ouji has even gone so far as to kill Hayama and use his body to create the fairies, a grim step meant to secure Kaori’s memory in a way that prevents it from being tainted. Her attempt to erase Azaka’s memories is thwarted when Azaka is knocked unconscious from behind by one of the fairies.

Satsuki Kurogiri, the teacher who has replaced Hayama, finds Azaka and strangely retains her own memories. Shiki arrives and informs Azaka that Kaori’s class has begun to disappear, heightening the sense of an invisible threat that reaches beyond the classroom. Azaka insists on investigating the suicide site, but Kurogiri dismisses the location as empty. Yet when they reach the site, a large portion of the old building has vanished without a trace, complicating the search and deepening the mystery. Unable to locate Ouji, Azaka falls asleep and is awakened later by the dog left by her roommate. Shiki conveys a message from Mikiya, revealing that Kurogiri’s true identity is a magus known as “God’s Word,” a figure capable of manipulating people’s recognition with words and serving as a countermeasure to his own power. The revelation casts a new light on Hayama’s death and the broader manipulation at work.

Armed with Shiki’s walkman and earphones to shield her from Kurogiri’s influence, Azaka rushes past the magus, unaffected by his power, and heads toward the suicide site. There she finds the Kaori-connected students entranced, holding matches and fuel as Ouji’s plan pushes them toward a shared, doomed ritual. In a tense standoff in the chapel, Azaka confronts Ouji while Shiki faces Kurogiri, each battle underscoring the clash between memory and truth. Ouji attempts to justify her actions by insisting Kaori’s memory must remain pristine, arguing that the harsh reality of her friend’s suffering must be sanitized by erasing the memories of those who might tarnish her legacy. Azaka counters by revealing that Hayama’s death was not a murder at all—it was a result of his drug abuse, and the rumor that he forced Kaori into a relationship came from overheard whispers rather than fact. The truth gradually emerges: nobody killed anyone in the way the rumor suggested, and Kurogiri had stolen Ouji’s memory to guide her toward a conclusion that would preserve Kaori’s image in the most favorable light.

Ouji refuses to abandon her conviction, attempting to kill Azaka with the magical fairies, but the two are ultimately overwhelmed by the truth of the matter and by the resilience of the two young women. Azaka destroys Ouji and the source of the magic that empowered the fairies, interrupting the death-focused plan before Ouji can enact her worst conclusion. In the aftermath, Kurogiri reveals that Araya Soren had requested his return to Japan to restore Shiki’s memory from before her accident and a long two-year coma. Shiki tries to kill him, but he simply tells her, “You’ll lose sight of me,” and she finds herself unable to see him, a cruel reminder of his manipulation.

After the conflict is resolved, Mikiya informs Azaka that Kaori has regained consciousness in the hospital. The bus arrives, but Azaka, moved by the moment, pulls Mikiya away and asks him for a proper date to make up for his earlier absence when he was with Shiki, a nod to events that would unfold in the next chapter. That night, Azaka remembers a childhood dream and begins to understand why and how she fell in love with Mikiya, a realization that adds warmth to an otherwise bleak arc.

The fate of Shiki’s memory restoration via God’s Word and the consequences for Kurogiri after these events are left largely unexplained, though the original novel hints at a longer arc involving these characters. In the epilogue, a new tension surfaces as Rio Shirazumi—a former senior student—kills a man in an alley and begins to struggle with what to do with the body. He starts to consume the corpse but stops, only to have Araya Soren appear and push him to break completely. The encounter seals Shirazumi’s fate as he embraces a darker path, awakening his own Origin in a moment that hints at the broader consequences of the mansion of secrets that lies at the series’ core.
