The supernatural possession trope is a storytelling wellspring found in folklore worldwide, from Hollywood’s demonic entities to the spirit-channeling tales in Indian cinema like Bhool Bhulaiyaa. Ghost Killer dives headfirst into this tradition with a distinctly Japanese action-comedy twist. Its high-concept premise is immediate and arresting: a timid college student’s life is violently upended when she becomes spiritually tethered to a deceased hitman.
We meet Fumika Matsuoka, a young woman characterized by a polite passivity that makes her utterly unsuited for the world of violence she is about to enter. Her life changes irrevocably when she stumbles upon a spent bullet casing on the street. This mundane object acts as a conduit, linking her to the ghost of Hideo Kudo, a professional killer recently murdered.
The film quickly establishes its central mechanic: Kudo’s spirit can possess Fumika’s body, transforming the meek student into an unstoppable fighting machine wielding all of his deadly skills. This sets up the core conflict, a dangerous and reluctant pact where Kudo needs Fumika’s body to exact revenge on the criminals who killed him.
The Physicality of Vengeance: Sonomura’s Action Mastery
The soul of Ghost Killer resides in its action, a visceral ballet orchestrated by director Kensuke Sonomura. An artist whose expertise in stunt work is evident in every frame, Sonomura treats action not as a chaotic spectacle but as a physical language. His style is a potent counter-narrative to the CGI-laden set pieces of global blockbusters.
Much like how South Indian directors such as Lokesh Kanagaraj are earning acclaim for the raw, grounded fight choreography in films like Kaithi and Vikram, Sonomura prizes clarity and impact. He understands that true tension comes not from the scale of an explosion, but from the tangible sense of risk in an intimate, close-quarters struggle. The camera remains steady, capturing long takes of intricate knife-work, lightning-fast parries, and brutal grappling. This approach forces the audience to feel the immediacy of every blow.
These sequences are potent forms of storytelling. The initial fights are a form of physical comedy; Fumika’s possessed body executes a perfect takedown while her mind, and her facial expression, recoils in horror. This is character development through choreography.

As the film progresses, the violence escalates, shedding its comedic skin for a darker, bloodier register that reflects the rising stakes. The final fight sequence is a masterclass in this philosophy, a brutal and emotionally charged confrontation that is the true climax of Sonomura’s kinetic vision. Every punch and stab carries the weight of the duo’s desperate journey.
The Body Snatcher and The Student: A Dazzling Dual Performance
The film’s fantastical premise rests squarely on the shoulders of Akari Takaishi, whose performance as Fumika is its emotional and functional anchor. Her portrayal is a brilliant execution of the “dual role,” a celebrated device in Indian cinema where actors like Sridevi in ChaalBaaz masterfully inhabited two distinct personalities.
Takaishi’s achievement is arguably more complex, as she embodies both the timid student and the hardened killer within a single body, often in the same moment. The artistry is in the transition—the subtle straightening of the spine, the cold focus that replaces terror in her eyes, the way her hands, once fidgety, become lethal instruments. As the unpossessed Fumika, her wide-eyed terror and panicked monologues provide perfect comedic timing. Then, in an instant, she is possessed, and her entire demeanor shifts.
Her physicality is the key to selling the concept. She convincingly portrays the experience of being a puppet, her limbs moving with an expert violence that her own mind is horrified by. This creates a fascinating dissonance where her body is the source of the film’s action credibility while her face provides its comic relief.
This internalizes a classic external conflict, offering a modern twist on a traditional storytelling trope. Her performance establishes a powerful chemistry with the ghost of Kudo (Masanori Mimoto), making his presence felt through her every action. It is a demanding performance that grounds the supernatural in a believable human reaction, allowing the audience to invest completely in her perilous journey.
An Inspired Premise with a Faltering Plot
Ghost Killer launches from an ingenious premise ripe with potential for both thrilling action and dark comedy. Yet, for all its conceptual strength, the screenplay falters in its execution, sidestepping the deeper implications of its own story.
The narrative introduces profound themes—most notably the issue of consent, with a male spirit forcibly commandeering a young woman’s body—but leaves them as unexplored threads in favor of simpler action beats. This feels like a missed opportunity for the kind of thoughtful genre deconstruction or psychological inquiry seen in Indian parallel cinema, where directors like Shyam Benegal would have dissected the power dynamics at play. Instead, the film chooses the path of a B-movie romp.
This choice leads to jarring structural problems. The story begins as a quirky supernatural buddy-comedy, full of unique rules and character dynamics, but devolves into a conventional and far less inventive crime-revenge thriller in its second half. The specificity of the premise dissolves into genre generalities. As the plot defaults to Kudo’s underdeveloped quest, Fumika’s own fascinating arc of empowerment and trauma is sidelined.
This damages the pacing and leads to a rushed final act with a forgettable antagonist. A hero is only as compelling as their opposition, and with an inconsequential villain, the climactic victory feels hollow, no matter how well choreographed. The script’s shortcomings ultimately hold the film back from the greatness promised by its clever concept and explosive execution.
Ghost Killer, a Japanese supernatural action-thriller directed by Kensuke Sonomura, had its world premiere at the Fantastic Fest in September 2024. It was also screened at the Glasgow Film Festival in March 2025 and the Bucheon International Fantastic Film Festival in July 2025.

The Review
Ghost Killer
Ghost Killer is a film of brilliant parts that fail to form a perfect whole. Director Kensuke Sonomura's action is a masterclass in kinetic filmmaking, and Akari Takaishi delivers a star-making dual performance that is a joy to watch. These phenomenal strengths are tethered to a shallow screenplay that squanders its ingenious premise on a generic revenge plot. Come for the spectacular fights and a captivating lead, but temper your expectations for the story, which ultimately lacks the spirit of its concept.
PROS
- World-class action choreography and direction that is clear, visceral, and inventive.
- A charismatic and brilliantly physical dual performance from lead actress Akari Takaishi.
- An entertaining and creative high-concept premise blending supernatural comedy and action.
CONS
- An underdeveloped script that fails to explore the deeper themes its story presents.
- A rushed final act with a weak and inconsequential antagonist.
- A jarring tonal shift from a unique comedy to a generic crime thriller.
