Koyuki enjoys her time with Natsumi, and has a very strong will to either build up good image in front of her or protect her as well. Koyuki's Keronian partner is Dororo. She found and rescued a stranded Zeroro (now Dororo) from a bear trap, brought him back to her homelike ninja village, and taught him the ways of the ninja. Under the order of the government, her ninja clan was dissolved for not having further value of existence to the country, giving her a chance(was also her only choice) at a real life in the city. Sharing many interests and the same positive attitude, Dororo and Koyuki have the most stable and cohesive relationship of the five Keronian/human child pairs. He trusts Natsumi to teach Koyuki to live a modern life. Chiruyo Tsukigami Voiced by: Chinami Nishimura (Japanese); Alexis Tipton (English, Funimation dub), Lisa Gonzalez (English, Funimation dub pilot) is an intelligent and meticulous classmate of Fuyuki. She is part of the Kishou Gakuen Shinbunbu or KGS, the school news club, and started out observing Keroro and Fuyuki's activities from a comfortable distance. Like Momoka, she has a crush on Fuyuki and is equally shy about her feelings toward him. She's obsessed with writing down in her notebooks all her observations about Fuyuki. She is 12 years old. Chiruyo later befriends Pururu, who helped her get closer to Fuyuki. Though they do not live together, they share a good friendship. Ms. Furbottom Voiced by: Ema Kogure (Japanese, first voice), Asuka Tanii (Japanese, second voice); Colleen Clinkenbeard (English, Funimation dub, cat form), Brittney Karbowski (English, Funimation dub, human form) Ms. Furbottom (子猫 Koneko) is Giroro's pet whitish pink cat that he first found during a rain storm. She accompanies Giroro in his tent from then on. She harbors romantic feelings for Giroro, though his obsessive crush on Natsumi get in the way of showing her feelings to him. Though she is friendly with most of the Hinata Family and the Platoon, she is openly hostile towards Natsumi as she sees her as her romantic rival. She sometimes unknowingly turns into human using one of Kururu's inventions. She quickly becomes Giroro's friend and became his pet after the Garuru Platoon's departure. Her human form bears a distinct resemblance to Cammy White of Street Fighter fame.
