‘Ghost Killer’ Brings Martial Arts Mayhem to Digital

A murdered assassin finds an unlikely ally in a university student in Ghost Killer, a Japanese action-horror hybrid arriving on digital platforms from 6 April. Combining martial arts spectacle with supernatural comedy, the film comes from director Kensuke Sonomura and writer Yugo Sakamoto, the creative team associated with the cult hit Baby Assassins franchise.

Blending high-impact combat with an unusual buddy dynamic, Ghost Killer follows the strange partnership between a restless spirit and an ordinary young woman suddenly pulled into a world of organised crime and revenge. The story begins when university student Matsuoka Fumika, played by Akari Takaishi, stumbles home after a disappointing night out and notices a bullet casing lying in the street. Curious, she picks it up and soon discovers the ghost of its former owner.

The spirit belongs to Kudo Hideo, portrayed by martial artist and actor Masanori Mimoto, a feared hitman who has recently been murdered under mysterious circumstances. Unable to move on, Hideo latches onto Fumika in a bizarre arrangement that allows him to interact with the living world. Whenever she holds his hand, Fumika suddenly acquires his formidable combat abilities.

What begins as confusion soon escalates into something far more dangerous. Determined to uncover who killed him, Hideo convinces the reluctant student to let him guide her actions as they investigate his death. Their search leads them into a volatile conflict between rival business factions and a shadowy figure from Hideo’s past.

That figure is Kagehara, played by Mario Kuroba, once the assassin’s protégé and now a key player in the criminal underworld. As secrets begin to surface, Fumika finds herself caught between competing loyalties while trying to maintain a semblance of her ordinary life.

Director Kensuke Sonomura is widely regarded as one of Japan’s most accomplished action choreographers, having worked as the fight director on Resident Evil Vendetta and several entries in the Baby Assassins series. Here he applies that experience to a film that balances explosive hand-to-hand combat with moments of humour and unexpected emotional connection.

Screenwriter Yugo Sakamoto, who wrote and directed the original Baby Assassins, injects the story with sharp character beats and an offbeat tone that allows the supernatural premise to coexist with grounded emotional stakes.

Since its debut, Ghost Killer has travelled widely on the international festival circuit, screening at events including Fantastic Fest, Beyond Fest, Sitges International Fantastic Film Festival and the Glasgow Film Festival. The Japan Times described it as superior action entertainment, praising its energetic fight choreography and inventive concept.

Ghost Killer will be available on digital platforms from 6 April.
