I would say BLASPHEMY TO GOD was non-vkei based on the video mentioned above (as far as I can see they do not wear make-up and all wear blue business-like shirts). However, in the one song of the video they sound exactly like GREGORY instrument-wise (similar to DISGUISE ON TEAR but with a melodic chorus (?)). I would say the bassist and guitarist could have been both from GREGORY judging by their hair/face and instrument sound but that is just speculation. No idea of the vocalist. It could be Iori if he sounds live a little different (similar style but voice a little different) and completely dropped all his vk look since he looks like a rather normal short haired office worker (to me).
It seems that ミスター and はる。 play in the (session?) band MAIDEN NATION together with クラオカユウスケ (えんそく, Gt.), アンディ (ギャロ, Ba.) and たけち (Sclaim, Dr.). It seems that はる。 is also part of おまんじゅう倶楽部.
