It does defenitely sound ambiguous, but according to my fairly alright knowledge of Japanese (my parents are Japanese, so I learned quite a bit of it), Ui was probably talking to her parents because sometimes, you can say "Onee-chan da yo" instead of something like "Yui-chan da yo" (It's Yui!); although it would sound a bit wierd. If Kiyuhito was here, I bet he would probably be able to tell us more about it.
