On June 23, 2026, the production team of the film "Shin Gekijōban☆Keroro Gunsō: Fukkatsu shite Sokkō Chikyū Mestsubō no Kiki de Arimasu!" released a new promotional trailer. The video is titled "Reiwa ni Kero! to Fukkatsu PV" and introduces the five members of the Keroro squad, known as "the slowest invasion force in the universe."
The trailer is accompanied by the new opening song "Mata Kaettekita Kero! to March," performed by singer ano and comedian Soshina (a rapper and member of the duo 'Soshina'). It features scenes of Sergeant Keroro, the squad leader, admiring his Gunpla kits as usual. Additionally, the other side of Private Tamama is shown: cute but terrifying when angered. Combat specialist Corporal Giroro has a crush on Natsumi Hinata, the cunning yet reliable Sergeant Major Kururu works on his inventions, and shadow warrior Sergeant Dororo laments being forgotten by Keroro.
The two mysterious Keronian brothers Aruru and Deruru—voiced by Jesse (SixTONES)—as well as the Earthlings including Natsumi and her brother Fuyuki, also appear in the trailer. Together with the Keroro squad, they face a new, overwhelming enemy.
The trailer underscores the humor of the series, which has been serialized in "Monthly Shōnen Ace" since 1999. The film is part of the 20th anniversary of the anime adaptation, which began in 2004. The screenplay and overall direction are handled by Yūichi Fukuda, known for the "Gintama" live-action films and the "Yoshihiko" series—this marks his first anime directorial work. Fumitoshi Oisaki directs, with animation production by BN Pictures.
In early June, an official collaboration with the "Mobile Suit Gundam" franchise was announced. In the film, characters encounter Gundam mecha, including Char's Zaku. To commemorate this, limited model kits are being released: the "Keroro Robo Mk-II (Titans Colors)" and the "RG 1/144 RX-178 Gundam Mk-II (Keroro Specification)." Original illustrations by Yoshizaki and Gundam designer Yoshikazu Yasuhiko highlight the collaboration.
"Shin Gekijōban☆Keroro Gunsō: Fukkatsu shite Sokkō Chikyū Mestsubō no Kiki de Arimasu!" opens in Japanese theaters on June 26, 2026. It is the first theatrical film in the series since 2010.
