What is Romantic Killer?
“Romantic Killer” is a live-action film based on the popular manga by Wataru Momose. The original manga was serialized on Shueisha’s app “Shonen Jump+” and was adapted into a 12-episode anime on Netflix in 2022. And on December 12, 2025, the long-awaited live-action film with a star-studded cast will be released nationwide.
The story is a wild romantic comedy about Kyoko Hoshino, a high school girl with zero interest in romance, who is thrown into a “romance-required” environment by the wizard Riri. Kyoko has her beloved games, chocolate, and cat taken away, and in their place appear a cast of charming, unique heartthrobs. The torrent of “romantic traps” packed with love-story situations has earned strong support from fans of the original.
Features of the live-action film
The 2025 live-action version builds on the strengths of the original manga and anime while adding film-original developments in abundance. The leads are four co-stars: Moka Kamishiraishi, Kyohei Takahashi (Naniwa Danshi), Masaya Kimura (INI), and Sota Nakajima (FANTASTICS from EXILE TRIBE). With director Tsutomu Hanabusa at the helm, snappy comedic direction blends with heart-throbbing moments, making it a fresh romantic comedy that will make you laugh and cry.
Genre and target audience
While it’s a romantic comedy, unlike conventional live-action adaptations of shoujo manga, it features plenty of gags, parodies, and meta elements, appealing to male audiences and anime fans as well. As such, it’s expected to draw attention from a wide age range once it hits streaming after the theatrical run.
“Romantic Killer” shines not only for its romance but also for its gags and brisk pacing. The live-action version looks set to meet the expectations of both manga and anime fans.
Romantic Killer: Synopsis & Work Info
“Romantic Killer” follows Kyoko Hoshino, a high school girl completely uninterested in romance, who gets dragged into a “forced romance mode” by the wizard Riri’s scheme. Kyoko suddenly loses her everyday joys—games, chocolate, and her cat—and in their place appear heartthrobs straight out of a shoujo manga. She meets transfer student Tsukasa Katsuki, childhood friend Junta Hayami, and the enigmatic Hijiri Koganei, and is tossed about by one heart-fluttering event after another.
Synopsis (No Spoilers)
The wizard Riri suddenly appears before Kyoko, presenting the condition: “You can’t return to your old life unless you fall in love.” Kyoko stubbornly refuses at first, but through unexpected mishaps and everyday moments, she gradually confronts the other characters’ true selves—and her own feelings. While following the classic paths of rom-coms, the protagonist’s strong personality and unpredictable turns keep things engaging to the very end.
