Kaana is an alien character living in a human society where extraterrestrials have become an unremarkable part of everyday life. She is a secondary character identifiable by her distinctive appearance, which includes green eyes and brown hair cut to about ear length, styled into two odango buns often covered with panda-themed accessories. She consistently wears a qipao dress featuring a panda appliqué, reflecting her deep but heavily misunderstood fascination with Chinese culture.

Her personality is notably high-handed, brash, and large in manner, often described as a large ham who is prone to a noble woman's laugh. Kaana acts with a tenuous hold on reality and a strong sense of self-importance, taking part in activities demanding the redevelopment of the Enohana district. She has a notable berserk button; mocking or insulting her antenna is something she does not take lightly. In line with her affected character, she has a great fondness for panda prints as part of her self-styled persona.

Kaana's role in the story is that of a recurring side character who adds to the comedic and social dynamic of the alien community. Her key relationships primarily involve her interactions with other aliens and the human cast, where her pretentious and easily provoked nature often creates conflict and humor. While her motivations are not deeply explored, she presents herself as someone seeking influence or recognition, particularly through her involvement in local redevelopment projects. Her development throughout the series is subtle, as she largely remains a consistent and static comedic figure. A notable ability, though not supernatural, is her capacity for grand, over-the-top dramatic expressions and her distinctive, commanding laughter.
