This was fascinating, despite everything that happens in the plot, one thing that always comes to mind is that the actual Hikaru is gone and dead permanently, quite tragic, that fact always hangs subtly over everyone's head, at least for us and the characters aware, more so for the former, it's already obvious but a shadow is constantly around that presses you in the face, so haunting.
