She shows up one series too late for me to when it really would have been interesting. I wanted to see her appear in UAF, and be a rival or nemesis to Julie. Even is she never had feelings for Ben, Ben liked her at one point and that would have been reason enough for Kai to be someone that gets on Julie nerves, or show her jealous insecure side that we all have deep down. (plus have you seen Kai in the photos from "A Benwolf in London", her boobs are big enough to be a Fairy Tail character, that is another reason for Julie insecurities)

Even if Kai and Julie ever appear in the same episode down the line in OV, there is no conflict anymore now that Ben and Julie broke up.
