Kaban

Kaban is a girl of short stature. She has black, short, and messy hair. She also wears a safari hat - that is reminiscent of a pith helmet - that is rather battered and has holes in its rim. For most of the series the hat has a single green feather, however, in Episode 11, Arai returns a red feather to the hat. The hat once belonged to Mirai. She wears a red v-necked shirt with black trims and a dark gray undershirt below that. She carries around a white backpack, for which she is named. She has grayish-white pants with red and black trimming, as well as black stockings and gloves. She wears brown shoes and has grey-blue eyes.

Kaban has a reserved, calm, and caring personality. She is not as outgoing as Serval when it comes to interacting with other friends, and her gentle voice and less animated body language contrasts her from Serval's hyper personality. She also does not make as quick remarks as often as Serval does and tends to think through her words more.

Kaban is also able to remain calm and think of solutions under pressure. In the battle against the Cellien in the first episode, she was able to devise a plan to distract the Cellien with a paper airplane. She was also able to create a sled to escape from the Celliens that were rolling down the mountain. Even under time pressure from the Owl's cooking trial, Kaban was also able to successfully cook some curry.

Her kindness shows when she is talking to friends such as Crested Ibis. Instead of insulting or criticizing Crested Ibis's singing, she decides to compliment her. She also cares for her friends and the Park's safety more than herself. She dove into the Black Cellien and was willing to sacrifice the boat to protect the Park, rather than use the boat to accomplish her goal of finding other humans. She's polite and appreciates all the help she received throughout the story, and she is thankful for the experiences she had in Japari Park. When tackled by Raccoon, she's initially surprised, and she never displayed anger or annoyance to anyone throughout the show. She is always willing to help others as is seen throughout the show.

Even though Kaban can be brave, she is also very easily scared. Throughout the anime, she screams "Do not eat me!" usually when she is jump-scared by a friend.

Throughout the anime, Kaban searches for her identity and learns that she is human; however, she remains unaware of her origins. In episode 12, one of Mirai's recordings from Boss reveals that she lost her hat on the Ferris wheel before departing the park. In the same episode at the party, the Common Raccoon tells her story of stumbling on Kaban's hat to Kaban and Serval. When Raccoon discovered the hat in the savanna area, sandstar from the eruption hit a strand of Mirai's hair in the hat, which surprised Common Raccoon and caused her to fall. A dark shadowed silhouette that rose from the hat appeared to be Kaban.

Kaban, along with Serval and other Friends (who are implied to be Raccoon and Fennec Fox), was last seen riding the Japari Bus, which has been repurposed as a boat, from the Kyōshū Region to the Gokoku Region. The group hopes to learn the fate of humanity by continuing their adventure elsewhere.
