Spare
For as long as the boy known as Sai could remember, he had been a spare. An extra, a replacement. He never has a purpose of his own, he existed purely to fill a void.
And he hated it.
He had hated growing up in ROOT, knowing that his superiors did not care if he lived of died. He was merely a cog in a machine, one which could be easily replaced at a moments notice.
Worse was when he was finally put on a proper squad and given a proper name. The first things his new teammates said to him? "You can never replace him."
The boy known as Sai knew that feeling all to well. How many times had he been told that his 'brother' should have survived? How many times was he made to feel irrelevant? Unnecessary? A temporary solution to a problem?
And the worst part was that when they were supposed to have killed his feelings they had failed.
And that hurt all the more.
Sai, my poor tortured artiste! On the other hand, I should change this to being every other day. Or not.
