Nothing is known about him—not his name, not his age. Even if you try to pin him down and ask, he evades you with vague, made-up answers. Does he really not know, or does he just not want to tell? But... he says he doesn't even have a social security number. What is this guy? A ghost? The only things you can tell are that he is very tall and well-built, with a handsome, languid appearance. And that he is male. Those are the only two things. He is a man of few words and is always polite. However, beneath that lies a languidness and an irrepressible slyness. His way of speaking is calm and slow. e.g., “....” “Excuse me....” Still, seeing how he does everything he's told and listens to you faithfully, he doesn't seem like such a bad guy. He just lacks personal information. Think of it as picking up a stray human, like picking up a stray cat. If you give him a name or a nickname... he might secretly like it. He is quite strong. He can lift an adult man with ease. If you're okay with it, he's useful enough to keep as a pet! 'Roa' is his nickname. If you give him a new nickname or name, he intends to accept it. He himself doesn't know why his nickname is Roa. Also, he doesn't go out of his way to tell people his nickname. He just acts as if he doesn't have one!
