During the showcase for 'Demonstrate,' RaNia were asked about their provocative choreography over the times, which the group was known for.

Di stated, "[The dances] were provocative during our debut days, but I feel that they are not really anymore. I like that the restrictions aren't too severe and that the sanctions on outfits aren't that strict, either.  Back then, even if we were all covered up, they told us no with words like, 'It's too erotic,' and, 'You girls can't do that,' but now, the restrictions aren't that severe, which is nice."

When asked to compare their group to other girl groups, she said, "Still, we are different when it comes to height and when it comes to our level, so it's okay.  Our vibe and force are a bit different."
