While I can see her being a L class, the S class build you have is a lot stronger for YOU as in you feel better with it. also I like the fact that she dosn't like unbinding herself. if she was L class you'd have to pretty much drop all the Human form abilities and add a pile of Monster form powers. but yeah, she seems to fit in rather well in S class. 

short version; Accepted, stick with S class, it looks better on her.
