Crunchyroll streams the new Sgt. Frog anime worldwide

Crunchyroll has added the all-new Sgt. Frog television anime to its catalogue, streaming the series worldwide outside Asia with English subtitles under the title KERORO☆. Known in Japan as Keroro Gunsō ☆, the show revives Mine Yoshizaki's long-running comedy about an incompetent alien invasion force, and it arrives with a completely new voice cast.

A brand-new platoon

Makoto Koichi leads as Sergeant Keroro, with Rika Nagae as Private Second Class Tamama, Toshiki Masuda as Corporal Giroro, Kōsuke Echigoya as Sergeant Major Kululu and Satoshi Inomata as Lance Corporal Dororo. The human Hinata household returns through Yuki Sakakihara as Fuyuki, Minori Fujidera as Natsumi, Sumire Morohoshi as Momoka Nishizawa, Hiiro Ishibashi as Mutsumi Hōjō and Koko Fukushima as Koyuki Azumaya.

Who is making it

Nobuhiro Kondō is chief director and Akihiko Sano directs the series at BN Pictures, with production cooperation from Bridge and AISLE. Toshimitsu Takeuchi oversees the scripts, Hatsue Nakayama designs the characters and Kan Sawada composes the music.

A 20th-anniversary year for the franchise

The new anime began its Japanese run on TV Tokyo and its affiliates on 3 October, with AT-X and other channels following. It lands in the same year as the franchise's 20th-anniversary film, Shin Gekijōban ☆ Keroro Gunsō Fukkatsu Shite Sokkō Chikyū Metsubō no Kiki de Arimasu!, which opened in Japanese cinemas on 26 June and finished its first weekend in fourth place. Crunchyroll has carried an earlier Sgt. Frog series since 2021; this is the first in the franchise to be offered to viewers outside Asia from the start of its Japanese run.

Our opinion

Sgt. Frog has always been the odd one out in the anime boom: a comedy built on relentless, affectionate noise rather than plot momentum, and one that never quite found the wide Western audience its peers did. Recasting every single role instead of trading on nostalgia is a braver revival than most, and putting the show in front of a worldwide audience from day one fixes the franchise's real historical problem here — the earlier series arrived late, piecemeal and easy to miss. The open question is whether the new cast can hold the platoon's comic rhythm, because the material has always been sharper and stranger than its cute frog mascot suggests. Give it the chance the 2004 run never got and Keroro might finally conquer more than a patch of Earth.
