Nana is precisely a moderate-sounding woman. Before she died, she was in her late 20's, so keep in mind her voice will sound more medium-toned rather than high-pitched. She can be very ill-tempered, and most times she is a big sailor mouth, almost never excusing herself, so don't be afraid to go all out. However, aside from those cons, she can be feminine if anyone is to ever get too close to her heart strings, - she is also a succubi.
