So apparently there was a live stream where Shibasaki Noriko (Shiny Colors' Chiyuki seiyuu) was doing a "internet sign event" for people who bought her new album. I'm not familiar with how it works or why it says "sign", but from what I read, people can send in digital postcards with their names on it and she would just thank the names like supachas. One particular bar master's name was called out, and one commenter picked up on the name and said, "Yukoku Roberu. It'll be funny if it's the Holostars one".
Well, Roberu just confirmed it last stream that he did send his name in, not his roommate's name, actually Yukoku Roberu. He actually had to talk to Shinove (and maybe some other manager?) to pull that stunt off. When it got called, he just went "Uhohoh!".
