Sgt. Frog’s 20th Anniversary Movie Reveals Cast and Music

After years of silence, Keroro and the platoon are finally hopping back into action — and the official website just made it real. The full trailer for Shin Gekijōban ☆ Keroro Gunsō Fukkatsu Shite Sokkō Chikyū Metsubō no Kiki de Arimasu! has dropped, giving fans their first real look at the long‑awaited 20th anniversary film. And yes, Earth is once again in immediate danger… because of course it is.

The new trailer doesn’t just tease the chaos — it expands the cast lineup and gives us a preview of the film’s theme song, “Kashippanashi Destiny” by ano, whose energetic style fits Keroro’s brand of absurdity perfectly. It’s a nostalgic return wrapped in a modern sound, and it sets the tone for a movie that clearly wants to celebrate two decades of green‑alien mischief.

The visual released alongside the trailer leans into that classic Sgt. Frog charm: bold colors, expressive character poses, and that unmistakable mix of comedy and cosmic stakes. It feels like a love letter to longtime fans while still inviting new viewers into the madness.

For a franchise that built its legacy on slapstick humor, heartfelt moments, and a surprisingly rich sci‑fi world, this anniversary film looks like a true revival — not just a reunion. Keroro’s back, the platoon is assembled, and Earth… well, Earth should probably start worrying again.
