I can't really say I have much thoughts about him the same way I do the Slow Damage cast, for example, but his idiosyncracies aside, he could've used a bit more screentime in the VN since while he's not the mastermind, his involvement with Vischio and ENED does leave room for potential (that and it'd be funny if he still encountered Motomi again outside the man's route), especially in what'd become of him depending on the route taken (since we only have a good idea if it's either Keisuke or Shiki's endings).

And just as a last note, I have a good feeling that even if the concept itself played a different role in the narrative, he himself served as some sort of inspiration for the plot point that is Euphoria (Maya's business).
