New CODE Agents Announced for Kamen Rider ZX
Fresh intel has arrived from the top-secret defense organization “CODE”! The special effects TV drama Kamen Rider ZX (pronounced “Zetts”) has just unveiled three new agents joining the fray. The roles of Code Number: Three, Five, and Six will be played by Tamashiro Yuuki, Koyanagi Kokoro, and Hirakawa Yuzuki, respectively.
Kamen Rider ZX is the latest series in the long-running Kamen Rider franchise, having started its broadcast in September 2025. The story has now entered a new, serious chapter where the protagonist, Ban Tsukumo / Kamen Rider ZX, learns of CODE’s dark secrets and is thrown into turmoil.
As this intense new phase unfolds, three battle-hardened CODE agents have emerged. The cast bringing these intriguing characters to life has now been revealed.
Meet the New Agents
The ruthless Code Number: Three is the agent who has taken over as commander, replacing the destroyed “Zero.” He’s a cold operator who doesn’t shy away from any means to achieve his objectives.
Playing Three is Tamashiro Yuuki, an actor known for his stage and musical work in productions like Touken Ranbu ONLINE, Yowamushi Pedal, and Lychee Light Club. This marks his first appearance in a tokusatsu hero series, and he couldn’t hide his excitement: “Being able to participate in a work from the historic Kamen Rider series is a dream-like happiness. And to think I get to Henshin… I can’t tell if it’s a dream or reality!”
Code Number: Five is a fierce agent who sees himself as CODE’s guard dog. Koyanagi Kokoro, who plays Five, previously caused quite a stir in the latter part of Avataro Sentai Donbrothers as the enemy executive Sonoroku.
For ZX, he declares he’s ready to raise more hell: “I consider this a ‘promotion’ from Sonoroku to Five, from number 6 to 5. I might even dream of becoming number 1 someday… I intend to advance with that ‘dream’ in mind! I can proudly tell my son his dad is a Kamen Rider! Please continue to enjoy the show!”
Code Number: Six is actually Miyamoto Kouha, the high school best friend of the Strange Incident Division detective, Nagumo Nasuka. After meeting Tsukumo in a dream, he regained his memories of being a CODE agent and decided to return to the organization.
Portraying Six is Hirakawa Yuzuki, who gained popularity playing Rita Kaniska / Papillon Ohger in Ohsama Sentai King-Ohger. Hirakawa mentioned the filming: “This time, as an agent, I’m challenging myself with action scenes using guns and such. And the Henshin. It was incredibly thrilling. It’s a different feeling from when I did the ‘Ohger Caliber’ in King-Ohger.”
With these unique and complex CODE agents now in play, all eyes are on how they will impact the story. Be sure not to miss the next episode airing on February 1st.
