ケロロ軍曹 [Keroro Gunsō / Sgt. Frog]

Mine Yoshizaki's Sgt. Frog has been a fixture of Kadokawa's lineup since 1999, following the absurd misadventures of a platoon of frog-like alien invaders who, rather than conquering Earth, end up living as a quirky, bickering family in a Japanese suburb. This long-running manga blends slapstick comedy, sci-fi parody, and gentle slice-of-life humor, with Sgt. Keroro's bumbling schemes and his squad's antics driving the series' enduring charm. Running for 35 volumes and counting, it remains a beloved staple of early-2000s manga culture, celebrated for its affectionate spoofs of anime, tokusatsu, and everyday Japanese life.
