I'm not totally sure but I think it is possible that 夢国文弥 was a member of Vurny too. 文弥 guitar. I don't have any source. I'm sorry. Just compared pictures. PS: you forgot to mention .幽城齋 脱退 as former bass player. Quote: https://www.vkdb.jp/NEWS_7027
Added Yuki Sai, thank you!
I compared 夢国文弥's blood type and birth date with 文弥 from Sirius (Vurny's OHP wasn't properly archived). They match up, and due to that you're most likely correct! I've merged those profiles, thank you very much!
