It has been revealed that a new theatrical version of the anime "Sgt. Frog", based on the popular manga by Yoshizaki Mine, will be produced and released in the summer of 2026. This will be the first theatrical version of the work in about 16 years since "Super Movie Keroro Gunso: Birth! Ultimate Keroro: Miracle Space-Time Island!!" was released in 2010. Yuichi Fukuda, known for the TV drama series "Yoshihiko the Brave" and the movie series "Gintama", will be the general director and scriptwriter. Fumitoshi Ozaki, who was in charge of character design for the TV series, will be the director, and Satoshi Koike, who also participated in the TV series, will be in charge of character design. BN Pictures will produce the anime.
As part of the anime's 20th anniversary project, a new anime movie will be released. A special trailer featuring Hinata Fuyuki and Keroro Gunso has been released on YouTube. It was also announced that singer and talent Ano-san, also known as "Ano-chan," will serve as the promotional captain for the 20th anniversary project. The special trailer also featured the debut of "Mata Kaette Kero! To March," sung by Ano-san and Soshina-san of the comedy duo Shimofuri Myojo. The song was newly composed for the 20th anniversary. The official radio show "Keroro Gunso no Kero! To Radio," featuring Ano-san as a guest, will be released on YouTube on July 3rd at 9pm.
Original author Yoshizaki Mine commented, "Those evil aliens will finally return to theaters! I'm full of expectations and anxieties, but I'm also happy and excited that the reliable staff have reunited! And the person who will be bringing together all these eccentric characters and staff is... Fukuda-san?! Seriously?! This movie was already an unknown, but now it's completely unpredictable. The only thing I can say is that I'm so excited it's interfering with my work! I hope everyone looks forward to the release!"
Director General Fukuda commented, "Director general may sound arrogant, but basically, once I write the script, the animation director does almost all of the work of making the animation, and if something comes up, I'm allowed to have a say in it or provide a little direction during the dubbing. I've been a big fan of 'Sgt. Frog' since it was aired on TV. At the time, I was still a scriptwriter for variety shows, and I remember writing scripts for shows while watching 'Sgt. Frog', which I remember very fondly. I love parodies, so when I saw 'Sergeant Keroro' I was half-surprised and thought, 'Wow, you can do something like that?'. I really couldn't help but envy their unrestrained style of work. That's why I was extremely happy when I received the offer to do this."
"Naturally, I have a favorite character, but I won't mention them here because that would make me seem biased. In writing the script, I received a lot of help from the original author, Yoshizaki Mine, the producer who has been involved since the TV broadcast, and the director, and I studied and studied and completed it. I think it's a work that really lets me express the admiration I had for 'Sergeant Keroro'! The theme song is sung by someone who makes you think, 'What!? This person!?' and the guest voice actors are people who make you think, 'Someone like this! You're kidding!?' so I think there are plenty of surprises in store while still keeping the fun of 'Sergeant Keroro', so please look forward to the release next year!"
Director Oizaki said, "The sergeants are back after a long time! And it's great just to be able to be involved again after such a long time, but it's also a miracle that I get to work with Yuichi Fukuda. I'm having fun creating this miraculous collaboration between the Fukuda world and the Yoshizaki world. It's a very lively, noisy (laughs) and fun film, so I think you'll look forward to it being released!"
Character designer Koike said, "The TV series ended in 2011, so this is the first time I've been reunited with Keroro and the others in 14 years. That means the Pekopon invasion has still not been accomplished (laughs). Keroro has played a big role in my career. I want to make a movie that can be enjoyed by people who were children back then, and children today as well!"
Watanabe Kumiko, who plays Sergeant Keroro, commented, "W-What?! The squad that is making the least amount of progress in its invasion in the universe!! The squad that only does it when it needs to!! The squad with a captain that prioritizes Gunpla over the mission!! But up to this point, this is just my meta-based fun, you foolish Pekopons! Now is the time for you to come to the theater and experience the true power of my squad!! Gerogerogenerogener (Black Vortex Resonance) So, hey, hey, I'll be waiting for you at the theater! I've made a promise with you."
Etsuko Kozakura, who plays Private Tamama, said, "I can't believe it, a new movie version of 'Sergeant Keroro' is coming! I never imagined something like this would happen. I'm so happy. It's rare that I get to meet all the cast members at once, so the dubbing will surely be a festive atmosphere. I'll be bringing plenty of throat lozenges with me to the set so I don't get hoarse from laughing too much! I'm looking forward to seeing what kind of story it will be. I hope all the fans will join in the fun too."
Kuwashima Houko, who plays Hinata Fuyuki, said, "After some time has passed, I am surprised, just like everyone else, to be taking part in the new film version of 'Sergeant Keroro.' We recorded the super special PV the other day, and it's only just starting to sink in that I'm really doing it! I hope to savor the happiness of being able to do dubbing with that cast team, including Watanabe Kumiko, who plays Sergeant Keroro. See you at the cinema!"
Ano said, "I am very much looking forward to the new movie version of 'Sergeant Frog' which will be released in the summer of 2026. I have watched many of 'Sergeant Frog' since I was a child, including the comic books, TV anime and movies, and as you can tell from my social media, I love it so much that I have a lot of merchandise! I have been appointed as the 'New Member of the Keroro Platoon, Ano's Publicity Captain' for 'Sergeant Frog', and I had the opportunity to sing a new version of 'Kero! to March' with Soshina, a song I have been listening to for a long time. My teacher incorporated many of my ideas into the lyrics. The recording was also fun. I hope you will look forward to it along with the new work!"
Soshina said, "It's Soshina with the glaring eyes. I'm overwhelmed that I can sing the new version of 'Kero! March'! I really owe it all to Ano-chan. I'm grateful. I was able to sing the solo part that was sung by Kakuta Nobuhiro a long time ago, and as a fan of a certain pachinko machine, it was a great honor for me. I would like everyone to hear this version more than the theme song for the movie version of 'Sergeant Frog', which was sung by Harisenbon!"
