Jinora and Kai, often referred to as 'Kainora' or 'Jinkai' by fans, share a strong bond that began when they first met in a small village in the Earth Kingdom. Their relationship strengthened during Kai's airbending training, and they spent much time together, even going on adventures such as looking for young sky bison. Jinora expressed romantic feelings for Kai early on, often blushing in his presence and offering to teach him airbending moves. They were even captured together by bison rustlers, but were freed with the help of other airbending students and Tenzin. By 174 AG, Jinora and Kai had started dating.
