I recently got to know this "interesting" group. I really liked them!!!!
Ok since they got different names in guys/ladies, I shall just write their colors.
Frankly speaking I liked them as fudanjuku rather than NFS. I feel that some members are better off to be fudanjuku than NFS (my own opinion), while of cos there are others who can be both.
Leader purple: can be both but I preferred her as guy
pink: can be both but like leader, I liked her as momotaro
blue: I can see that she doesn't mind being NFS but I don't find her attracting as a girl. But in guy's clothes, she's awesome!!!
red: can be both. She's pretty in girl and handsome in guy. She's popular among fans
green: can be both. She gives me a feeling that she preferred to be in NFS rather than fudanjuku
orange: I felt that if she can choose, she would rather be in fudanjuku than in NFS. She always seems awkward as girl. Frankly speaking, I liked her as guy as she's cool in it
yellow: Maybe she's rather new, she looks so shy. Can be both. Like red, she's pretty in girl, handsome looking in guy
Well my fav is green
