1.) My favorite girls in that band are a tie between PAREO and CHU2. I was in love with both of their designs when I first heard about them, they're also a cute pair with each other.
2.) My third favorite girls in that band are a tie between LAYER and MASKING. They both have a good deep singing voice, though I never heard MASKING sing before. I bet it would be as good as LAYER's voice.
3.) My least favorite girl in that band is LOCK. I don't pay attention to her as much as the other RAS girls. I like how she was able to find a band that she could show off her guitar skills, no matter how many times she was rejected.
