Spoiler for EP5:

As far as we know, Erika has NO link to Rika at all. She's just Bern's piece, and Bern is a troll. xDD

There have been theories she's an "alternate" Rika who didn't care about her friends and just about the mystery and getting out herself. Which would be kinda cool. (lol Erika and Hanyuu)
