The familiar nodded absent-mindedly, his mind focused on the man's thoughts.
"Ruu is simply a tool, that is why." His answer came naturally. He picked up a Blu-ray box and started to read what was written on the verso. "It looks like humans to accomplish its task."
He kept silent after that. After a minute, he put back the movie where it was initially. Maybe he should explain things a bit better?
"Ruu is an artificial construction. Everything is an imitation. Bones, flesh, blood. No gender. Doesn't have brains like you, it has magic core instead." He placed his left hand where, were he a real child, his heart would have been. "Everything is empty here."
He walked up to the television and stared at his strange reflected image.
"It was born to obey. To be useful to the Master. And to protect nature. It doesn't require more than that." He could never be like the humans even if he tried because he lacked in so many areas. Ruu placed his hand on the screen, wondering how it felt to be one of them. No matter how much he would ask, no clear answer could be obtained. It was something to experience by yourself. Just like how he couldn't reach his own reflection through the screen, it would be forever inaccessible.
He felt the urge to yell his frustration, but simply kept it sealed inside as he always did.
After a moment, he just sat, facing the TV. The occasions to interact with others were too few in his long existence. He could rarely get past the barrier of appearance because of the ridiculous look his Master deemed to grant him. And people would never exchange serious words with unknown kids. Some had demonstrated a strange kind of compassion in the past, but never did it lead to something constructive.
He was a monster after all. Unable to understand a world which had evolved faster than he could adapt, it was ineluctable for humans to perceive him as such. Nobody would expect him to have such strength with such a small body. People eventually would get afraid of him and either chased the Familiar or would run away.
But it had changed tonight. For the first time in three centuries, someone reached for him. Lancer even allowed physical contact. Circumstances, as they were, didn't allow for discussion, yet Ruu was still grateful for it. As impossible to express it in words as it could be.
For once, he had found people with whom he could discuss and pass time. People who wouldn't consider him strange or worse. So, he tried showing gratitude by preparing something to eat. But he had failed miserably. Even if the words addressed to him were kind, even he would understand after seeing what he did.
But he still had a chance to help miss Haku, like she had been called. Luck or not, it would be idiotic to waste a chance to redeem himself. And all he had to do was to prove his worth. Because there was no point in useless material, he will do his best to complete the task at hand.
"Ruu is ready for the mission," he said, with a military salute.
