>>3331916Looking for this, there seems to be a thread on zerochan (/2710818) with the same image, which claims the two characters present are Akuno Hideo and Kashiwagi Tsubasa from idolmaster side M, however neither of them really look like that.
Hideo Akuno DOES seem to have some sharky stuff going on through when I google his name and go images. So maybe it's supposed to be him somehow? I don't know.
