She started using the name "Reol" rather than her real name because she wanted to be someone other than herself but also she liked the name "Reol".
She mentioned that the reason behind naming the club "Secret Society L" was that "L" stands for Listeners (also the "left hand"), while her initials "R" stands for the "right hand", so both hands (left and right) work together.
