Netflix is slipping back into the Parasyte universe with a new live-action chapter built around Shioli Kutsuna’s most demanding role to date. Parasyte: Tamiya will star Shioli Kutsuna (Sanctuary, Deadpool 2) and will stream in 2027.
Parasyte: The Grey creator Yeon Sang-ho is returning, having developed Tamiya and co-written the scripts with Ryu Yong-jae. Wowpoint, The Grey producer, is also back, with Kensaku Kakimoto (Glass Heart) and Kazuhiro Nakagawa (Double, Bullet Train Explosion) directing.
The move comes off the back of Parasyte: The Grey’s breakout success, after it spent four weeks at the top of Netflix’s Global Top 10 Non-English list in 2024 and reached number one in 34 countries. Tamiya will develop the story further, but this time the franchise is centering one of its most morally ambiguous figures and giving her to a performer who’s used to shifting between worlds, from Japanese drama to Marvel’s R-rated corner in Deadpool 2.

In the original manga, Ryoko Tamiya is a parasite who takes over the body of a high school teacher. Initially brutal and indiscriminate, she gradually learns from her human surroundings — and upon witnessing a parasite and human sharing a body, begins to wonder whether coexistence might offer her species a better chance of survival than conflict.
That pivot from cold predator to something more questioning and self-aware is what makes the character such a rich canvas for a live-action rethink, and it’s where Kutsuna comes in.
Parasyte: Tamiya will tell Ryoko’s story from the inside: the original human, the parasite who inhabits her and the evolving creature caught between two worlds. Kutsuna plays the character, and said it was “the most challenging role I have ever played in my acting career.”
For an actor who’s already crossed borders, languages and genres, the suggestion is that this performance will ask her to inhabit three intersecting personas at once: teacher, invader and something new that doesn’t neatly belong to either category.
Yeon is clear that Ryoko’s interior conflict is the real engine of this spin-off. “Ryoko Tamiya is a truly captivating villain in the original manga,” said Yeon. “Her struggles over the nature of her own existence are what elevate the original Parasyte from a simple hero-based manga aimed at kids to something deeper. She’s a fascinating character, which drove me to want to tell the story of Parasyte through her perspective.”
“I wanted to convey her perpetual struggle over the need for parasites to coexist with humans and the issue of their survival, and how she suffers setbacks and learns over time. I think the anguish she experiences is the essence of Parasyte.” That anguish, refracted through Kutsuna’s performance, is positioned as the connective tissue between every adaptation so far — the films, the anime, the Korean drama — and this new iteration.
Parasyte is a major IP in Japan, having previously been adapted as a film series, an anime and a Korean drama. With Tamiya, the creative team is effectively asking: what happens if the “villain” becomes the emotional anchor of the story, and her crisis of conscience becomes the core of the franchise?
On the craft side, Yeon is promising a series that doesn’t just retread the ground laid by The Grey. “This series, which is currently being edited, brings new things to the table compared to past entries in terms of story, cinematography, action, production, you name it,” said Yeon. “It firmly reflects the vision of both directors and is made with great respect for the original manga.”
For Kutsuna, that vision means playing a character who’s constantly negotiating between worlds: alien and human, parent and predator, subject and scientist. For Netflix, it’s a bet that audiences who showed up for Parasyte: The Grey’s body horror and social commentary will follow the franchise into a more introspective, character-driven space — as long as there’s still enough viscera and velocity to make the existential questions hit like a parasite burrowing under the skin.
