She has no official english name yet, nor do any other characters (with the exception of Georg Prime, Lorelai, and any other returning chacter). Anytime that you read one of these characters names, it is simply a translation from the Japanese version. As we have seen in the past, their can be several variations of these names before the game is actually translated and consequently every character has an official name. Some examples that I can come up with off the top of my head are Borus (Bolus) from S3, Brandeau (Brand, Bland, etc.) from S4, and Fubar (Hoover) from S3. Someone fluent in Japanese and English could probably explain it better, but the multiple variations in the translated names is due to the fact that the Japanese alphabet is so drastically different to the English alphabet, that it makes it almost impossible to get an exact translation of just about anything.
