As the prisoner explains how he is 'a novelist who writes in reality', a strange being accompanying him traps Shinjuurou in a vision where he is a cameraman shooting a film about a war that never happened. As Shinjuurou becomes curious about whether the director is involved with one of the actresses, he gets the nagging feeling that there's a mystery to be solved. As Shinjuurou loses grip on this reality, he discovers the director has been killed and believes himself to be the culprit.

Shinjuurou is approached by Yajima, an old friend of Rinroku, who found a piece of manuscript in a book given to him by an inmate whilst he was in prison. After discovering Yajima's wife Takiko's fingerprints on the paper, Shinjuurou informs Rie, who investigates how the book relates to Rinroku. Shinjuurou later hears from Yajima about how his children disappeared and his wife went blind, allegedly having an affair with Rinroku. Shinjuurou looks at all the books Rinroku bought from the Yajima family, finding more hidden codes which are revealed to be from Yajima's children. As it turns out, Rinroku had helped the children and placed them in child care to avoid Takiko's neglect, and they are soon reunited with Yajima. Afterwards, Shinjuurou confronts the prisoner who gave Yajima the book, learning something shocking.

At the unveiling of a statue created in memory of three youths who sacrificed themselves to dispose of a bomb, two people who were snuck in to try and unveil a purported scam behind the story are found murdered inside the statue. Shinjuurou initially suspects the statue's commissioner, Hakuro Shimada, as the murderer, but Inga's question proves his innocence. After a brief depression and a pep talk from Kazamori, Shinjuurou deduces the culprit to be the statue's creator, Youko, who killed the men before they were transported, before later revealing the location of gold bricks that Hakuro had hidden.

It is revealed that Kazamori was actually a program known as RAI, one of the last built by Komamori before they were outlawed. As Kazamori is accused of killing the corpse that was assumed to be him, Shinjuurou and Inga download Kazamori into a doll before he is taken into custody. After discovering that the corpse was an outside and learning that Kazamori's maintainer, Dr. Taku, was also a RAI, Shinjuurou and others soon discover the culprit is Komamori, who faked his death using the body of the real Dr. Taku so that his RAI wouldn't be used by the military. After Komamori is arrested, Kazamori moves his consciousness to a doll of a girl so he can continue its life.

Rie calls on Shinjūrō and Inga to accept a request from Mitsuko Sasa, whose adopted brother Kazamori caught on fire and died, allegedly related to a curse from her father, Komamori, who died in a similar manner seven years ago. As Izumi's group conducts their own investigations on the cause of Kazamori's death, Inga uses her powers to reveal that Kazamori is actually a supercomputer.

Whilst the police suspect Hisako's lover to be the culprit, her daughter, An, believes someone else is behind the murder and calls on Shinjūrō to investigate. Their investigation leads them to look into an idol group Hisako managed named Yonagahime 3+1, one of its members of which, Eri, was allegedly killed in a terrorist attack. Inga uses her powers on one of Yonagahime's members, who reveals that Eri never existed and was just used by Hisako to skyrocket the band's popularity during a war.
