Summary
Robots can't feel. That's a fact that remains. They can't feel anything. Pain? No. Warmth? One can only wish. Cold? Definitely not.
Unless…? Oh well. Scratch that. It's not really worth thinking about anyway.
Subject 088 whirred to life. By who, I wonder so. Well, it's none other than the questionable mechanical genius Dr. R, also known as Kamishiro by his friends - no, colleagues. His life goal was to create, well, life.

Summary
Nobody knew until it was too late. But a day later, in a blink of an eye, the star everyone loved so dearly was gone.
It's been years. Perhaps it's unhealthy. Perhaps it's insane. But Rui has brought him back, if only to bring himself a sense of happiness and peace.
But with the robot left uncapable of emotion and Rui meeting with old friends once more... The robot slowly uncovers the truth of it's own existence as everything seems to slowly fall apart.
