Quan?
[My calling now is not too far from what it was before]
uh, not sure about that
[though I don't play with you much, friends and peers, not anymore]
well, he did go a way different from all the Qu's
[I am tired, weary; Do I even still exist?
I can't feel my limbs, but through my work I will persist!]
Well, how would you feel if you starved for so long, yet were too stubborn to give up?
[Though short, unknown and ugly may all well be in command
they do not see how they are mere puppets under my hand]
Not sure about that, either.
My guess match the following hints:
The answer is a person.
The answer exists in the game's world, i.e. it's not something the player could be aware of but not the characters.
The existence of the answer could be questioned.
The answer is quite obscure, and of very little importance to the game.
It's unknown whether the person is alive or dead. (I mean, Quan did appear in a secret scene with Vivi and Quina, right?)
Just another random guess.
