sister after learning that Keroro is also on the planet and seeks him out for a “battle”, going after Natsumi due to her affiliation with the Keronians. Although the Hinata's and the rest of the Platoon initially believe they are actually fighting, it is soon revealed that they are just play fighting and that they used to do it all the time as kids. After this incident, Kogoro and Lavie decide to remain on Earth and make a living, though Kogoro has trouble landing a paying job due to his lack of experience and strange personality. He ends up spending most of his days at home or helping out the platoon in their schemes. He is likely a parody of the character Gavan from the Metal Hero Series Space Sheriff Gavan. It only takes him a split-second (0.003 nanoseconds in the anime) to transform with his suit. (This also is a parody of the length of time it takes Gavan to transform, although Kogoro's transformation merely requires him putting on a helmet.) Lavie Voiced by: Tomoko Kaneda (Japanese); Leah Clark (English, Funimation dub) Kogoro's sweet natured younger sister who wears rabbit ears. She arrives on Earth with Kogoro and assists him in tracking down Keroro by chasing Natsumi. After their pretend battle, both decide to remain on Earth. Because Kogoro never gets any work, she supports them financially by working part-time jobs, and eventually becoming a television star along with her brother. There is a character from the anime Mado King Granzort with the same name and is a long ears race person (presuming that she's kind of a reference to him) who is a primary character in the Granzort Series. She frequently apologizes for her brother's bizarre behavior (sometimes unnecessarily) has become a recurring habit of hers. She is also the only one who can accurately read her brothers emotions and can always tells when he is actually upset or angry despite always looking and acting positively. Much like her brother Kogoro, Lavie is a parody of the character Annie, a partner of the eponymous character in Space Sheriff Shaider. In the English manga, her name is "Rabbie." Sumomo Voiced by: Juri Ihata (Japanese); Caitlin Glass (English, Funimation dub) Sumomo is a member of the Axolotl, a race based on newts in the same way the Keronians are based on frogs. In the manga, a girl finds Sumomo. Sumomo
