2nd Dyz
I don’t have reliable specific information about 2nd Dyz in my training data, so I can’t provide accurate details about their activity period, lineup, or discography. Rather than risk giving you incorrect information for a fan site, I’d recommend checking vkdb.jp directly or consulting Japanese VK community resources, which would have verified details about their history and musical style. I apologize that I can’t provide the profile you’re looking for.
