Back to the good guys, sadly, the parts about figuring out the composition of a Ganma Eyecon barely had any development in this episode as everything about it can be easily summed up as something that they are still trying to figure out, but they are close in getting it. This is understandable since the episode is more focused on the plot about the painting Ganma, the establishment of Igor's plan, and some stuff about Necrom Specter and Alain.
Meanwhile, Alain and Necrom Specter's story continues as we discovered that Necrom Specter can do more than just bow to Alain and do his bidding. The guy can still go places that is familiar to him, such as the riverside. I am not sure if this is zombie reflex or Makoto's soul trying to fight back, but it is an interesting scene and kinda gives the audience the idea on up to what extent Alain's power holds Makoto's Rider form. As for Alain, surprisingly, he starts to become more vocal about his life with Fumi, the takoyaki vendor.
Sadly, this rather charming encounter ended as all the major players of the episode arrived; to put it simply, the Ganma of the arc, Kanon, Takeru, Alain, and Necrom Specter. As expected, a fight ensues as Takeru protects the Ganma's right to paint while Alain wants him gone or what Igor stated later, re-educated. What surprised me the most about this encounter is that it adds another layer to the Ganma World. Not only that free will is basically dead in that world, but culture and the arts, and the true concept of bonds and friendship are dead in that world too. Yes, it is a utopia, but the thing that makes a world interesting at the first place was gone ages ago.
As for the Ganma, he managed to escape thanks to the fight between Igor and Ghost. As for that fight itself, aside from some Ghost Toucon Benkei Damashii action, there's nothing much to say about it. The episode ends with Necrom Specter still under Alain's control, and Benkei happy that Takeru is willing to make more friends.
