Two things, first of all she is apparently categorized as a main protagonist and she seems to be dedicated to the main heroes called Keiichi and Satoko. I think it might be a case of psycho bodyguard/love interest, sadestic and obsessive but when that sort of focus is used against those that might hurt the main heroes it creates no conflict, which makes the classification rather challenging. Here is one source I used. Have a look see. You can also check out TV Tropes for cliff notes.
