We don't how Emoto will end up, so I think his angst might be a bit more understood when we near his end, whenever that will be. I mean, he killed Rokuro, so I;m pretty sure he will have some sort of confrontation with Kengo and it might lead into the identities of Gamou and Hayami and Tatsugami and whatnot.
But I'm actually really liking Virgo as a villain. The suit looks a lot better in action, even without the gorgeous CGI wings. The seiyu for Virgo also is pretty sick, so I'm enjoying her a lot. I actually enjoy characters who are like Emoto and are completely different when we get to know them. I mean, as long as it doesn't go all Kiba in the last few episodes of Faiz (Or Kiba in general throughout Faiz), I think Emoto will be a pretty good villain.
I'm also hoping we get a tiny bit more on Tatsugami. He's sorta been relegated to the just heavy duty lifting and not much beyond that.
