As of late, I've been watching MKR again, this time all of it in the dubbed version. The voice actress that they cast for Hikaru (Julie Maddelina) always seemed so wrong for Hikaru compared to the original Japanese version. In the Manga Hikaru is often picked on by her classmates and also Umi for being "boyish" or that she "talks like a boy". The second statement could mean two things - either her voice sounds like a boy's or that she uses the speech of a boy. In Japanese there are differences between the words used by male and female speakers. The reason for this little note is that Julie's cute little girl voice in the English version somehow seems more natural for a person of Hikaru's stature, she really is a little girl. So was it possible that those who produced the original version made the casting mistake? Most likely we'll never know, unless I'm able to meet with one of the Clamp team someday.
