The trailer sees the gang dealing with the sudden appearance of mysterious monsters in Shibuya, along with other situations. One shot sees a Gundam protecting Keroro’s mech from an attack, while another features an Itano Circus involving a Death Star-like object.

The Sgt. Frog anime are inspired by the KADOKAWA-published manga by Mine Yoshizaki. The general premise involves the daily lives of a group of hapless alien invaders and the humans they find themselves living with.
A TV anime premiered in 2004 and ran for 358 episodes across multiple seasons until 2011. A 24-episode series titled Keroro aired a few years later in 2014. A few movies were released between 2006 to 2010, with the last being SERGEANT KERORO: The Super Duper Movie -Adventure in Space-Time Island-.
A new TV anime, featuring a fresh cast, is set to begin airing in the Fall 2026 anime season, after the debut of a musical in September.
Viz Media describes the first volume of the manga as such:
After Sgt. Keroro blew his cover and lost his top-secret weapon, the frog-like alien has been cut off from the homeworld. To make matters worse, he’s lost communications with the rest of his platoon. Now he has taken cover in the Hinata family household, where in exchange for doing his share of the chores, he gets his own room from which to secretly devise new plans of world domination!
