The World of Kanako 2015

Here is the rephrased section:

Akikazu Fujishima, once a respected detective, now wallows in the depths of despair following his precipitous downfall from grace. The trifecta of loss - job, marriage, and daughter - has reduced him to a shell of his former self, an unstable and dysfunctional drunkard. Years later, his ex-wife Kiriko approaches him with devastating news: their estranged daughter Kanako is missing. Akikazu’s investigation into her disappearance is marked by a haphazard approach, often involving harassment and intimidation towards those who might have information - including Kanako’s former classmates and teacher, Miki Nakatani. Despite his unorthodox methods, he uncovers that Kanako had become embroiled with a group of drug users, leading him to suspect she was manipulated into addiction.

Flashbacks to three years prior reveal the tender bond between Kanako and Sigon, a middle school student who harbored a secret crush on her. Sigon’s unrequited love eventually led him to attend a party with Kanako, where he was drugged and brutally assaulted. Consumed by anger and hurt, Sigon sought revenge against Kanako but ultimately couldn’t bring himself to harm her. Instead, an unseen figure intervened, ending Sigon’s life with a fatal stab wound.

In the present, Akikazu finds himself in the clutches of the Yakuza, who subject him to a grueling ordeal of physical torture and brutal violence, culminating in the gruesome murder of Kanako’s gang member friend Matsunaga. As Matsunaga takes his final breaths, he imparts harrowing truths about Kanako’s motivations: her unrequited love for Ogata, a “weak boy with a cute face,” drove her to form alliances with a group of thugs who brutalized him to the point of suicide. Kanako’s subsequent desire for revenge led her down a dark path, and Matsunaga’s own feelings for her only intensified as he helped her steal incriminating photos. The Yakuza then informs Akikazu that Detective Aikawa is complicit in the prostitution ring and has already silenced several of Kanako’s criminal associates with extreme prejudice. They provide Akikazu with a firearm and dispatch him to confront Aikawa at his home.

As a torrent of violence erupts, Akikazu brutally violates Aikawa’s wife, only to subsequently ensnare her and their young son in a hostage situation orchestrated to lure Aikawa into a deadly confrontation. The two men engage in a fierce and bloody struggle, with Aikawa ultimately succumbing to his primal rage by taking the life of his own wife. Miraculously, Akikazu emerges from this brutal ordeal unscathed, alongside his now orphaned hostage. The arrival of Detective Asai and his police colleagues serves only to accelerate the carnage, as they mercilessly dispatch Aikawa. Seizing the opportunity for escape, Akikazu makes a break for it by striking down Asai with his vehicle, vanishing into the chaos.

In the aftermath of this devastating sequence of events, Akikazu returns to a former acquaintance, a teacher whose life has been forever scarred by her own dark secrets. Having come to a gruesome realization - that the student she had questioned earlier was among those brutalized in the depraved images captured by Kanako - and having exacted a terrible vengeance upon Kanako herself, the teacher’s world is now consumed by guilt and despair. Akikazu, driven by his own unfathomable pain and desperation, forces this traumatized educator to exhume the grave where she had buried Kanako, despite the teacher’s protests that their futile search will be in vain due to the recent snowstorm’s obliteration of any lingering clues. The educator, desperate to escape the clutches of this ruthless tormentor, attempts to flee, but Akikazu remains steadfast in his determination to uncover the truth about his daughter’s fate. As the film draws to a close, Akikazu vows to assume the role of executioner himself, consumed by an unyielding resolve to deliver his own twisted brand of justice.
