Description
Fumikazu Haba is a character who appears exclusively in the twenty-second film in the series, where he plays a pivotal role in the central mystery. He is a thirty-one-year-old man whose life has been defined by his professional ambitions and complicated loyalties. His past reveals a strong but frustrated sense of justice, as his initial dream was to become a judge. This path was cut short after he disrupted a graduation ceremony at the legal training institute, an outburst that cost him any chance of a legal career. Following this setback, he found himself in a hopeless situation until he began working closely with a public prosecutor named Makoto Kusakabe, with whom he formed a strong two-year partnership as an assistant.

Before his apparent downfall, Haba was also an aspiring lawyer and was placed in the law offices of Kyoko Tachibana as part of a security monitoring arrangement, as his previous outburst had drawn the attention of authorities. Over time, he and Tachibana grew close and became lovers. His dedication to investigative work led him to break into a game studio to find evidence on hackers targeting Japan's space agency, an act that resulted in his arrest. After being taken into custody and interrogated by the Public Security Bureau, including an agent named Rei Furuya, Haba was reported to have committed suicide in his cell, an event that devastated both Kusakabe and Tachibana and became the catalyst for the film's events.

In the present day of the story, it is revealed that Haba's suicide was in fact staged by the Security Police. This was done on the orders of Rei Furuya, who offered Haba the choice to abandon his previous life and continue working as a supporter for the Security Police, in part to stop the prosecutor's office from using and abusing informants. Now working directly under Furuya, Haba is alive and has become a supporter for the Security Police, the very organization that once arrested him. He remains deeply grateful to Prosecutor Kusakabe, believing that Kusakabe's own path was limited because of their association. This gratitude drives his most crucial action: he confronts Kusakabe in a recorded message, pleading with him to stop a terrorist plot and revealing that he is still alive.

Personality-wise, Haba is defined by a powerful sense of justice and profound feelings of guilt. He is haunted by the pain his faked death caused to those who cared about him, especially his former lover, Kyoko Tachibana. In a poignant moment, he weeps when he sees her again, and she reacts with anger and disappointment at the deception. Despite everything, he still seems to harbor strong feelings for her. His key relationships are the primary drivers of his character. His bond with Makoto Kusakabe is one of deep loyalty and gratitude, while his connection to Kyoko Tachibana is one of love and regret. His role in the story is that of the catalyst, a man believed to be dead whose secret survival is the key to both the antagonist's motives and the resolution of the conflict. His development shows a man who started as a disgraced legal hopeful, became a loyal but reckless informant, and was ultimately granted a secret second life within the very security apparatus that condemned his old one.
