Kim Hotal is Megumi's closest friend and a TERRA operative. When Kim was a child, her parents were killed in a Dolem attack in Australia. She joined TERRA in order to take revenge on the Mulians for her parents' deaths.

Kim starts seeing Souchi Yagumo, and although she feels guilty for hurting Megumi's feelings when she learns that Megumi likes him too, she is able to work things out with Megumi. It is also strongly hinted that Kim becomes pregnant by Souchi, as she appears to be suffering from morning sickness in two scenes near the end of the series.

In the movie, Kim is only seen in a short glimpse. In the manga she appears in a couple of scenes with Megumi.
