Touch
Sha Gojyo
Out of all of them, he wants it the most.
It really may not seem like it. He acts cool and aloof. He acts like he's got everything he needs and no one should have to worry about him, since he can take care of himself. He's a lone wolf, a hot tomato. He's comfortable with himself and confident enough.
However, he came from a world where touch was simply forbidden. He loved his mother with everything he had, but she would not return his affections. She beat him harshly, and whenever he asked or pleaded for the warm, soothing touch only a mother could bestow, she smacked him smartly for it.
Still, he never gave up. He did not come to detest touch like another of his group, but craved it more and more and more. When he finally did get to touch her gently, when he was able to place his hands to her face without her striking back, it was only because her heart had stopped beating. His hands had shook as he stared down into her lifeless face, still pleading for her to open her eyes, embrace him in a hug and tell him that everything was all right.
He never gave up searching for that touch. He is constantly going and lying with woman, and had been since he turned fifteen. He is constantly touching these faceless, nameless women who mean nothing to him. It is not really the satisfaction of the sex that he's looking for. Rather it's just the feeling of skin beneath his hands, and the sound of some woman calling his name as he did everything he could to please her.
It validates his existence, this ability to touch. It's demonstrated in the group as well, whether he's sliding a little too close to a certain brunet, fighting with his partner in the backseat or playing the 'I'm not touching you' game with the leader of their party. He is always getting each nudge, tickle, or punch he can get. He wants it more than any other of the members. It makes him feel as though he's there, and he matters.
As though his mother was wrong; he's not a waste, and never will be.
