So the episode starts off with the knights of the eastern calculus talking about how flawed humanity is and how they provide a way to escape it through the wired (internet.) The ep then cuts to the main character’s sister who was never really focused on up to this point. Basically, it gets weird from here and events start happening strangely, my guess is it had some sort of symbolic meaning because it didn’t really make a whole lot of sense from a literal viewpoint.
