So there's a Japanese TV show called Nehorin which discusses topics and has the guests appear as pig puppets to preserve their anonymity. The last two episodes have been on underground idols. Their names etc have been changed and voices distorted. I wish I could really understand what's going on. They were very interesting, mostly talking about the idols relationships with fans. They discuss things like what happens at lives, buppan and handshake events, creepy fans, stalkers, the love ban rule (one of the idols saying she has f*ck buddies). There's also things in there that I didn't know existed, some idols who play the pocky game with fan or take handbra chekis etc (was interesting to see Japanese fans post these in reaction to the show after). Anyway here are the episodes:
