(continued...)
When not fussing over symmetry, Kid is usually serious and logical. He speaks in a very sophisticated manner -polite but far from pretentious. He thinks things through, and knows when to retreat when the opponent is simply out of his league(however, this does not mean he would abandon a friend in need as a result). Despite all this, he isn't all serious business, all the time. He knows how to have fun -sometimes sneaking in a skateboard move during fights- and will play games with his friends if asked to. He is generally agreeable and easy to get along with, because he is modest despite literally having a God's body.

Kid has a good heart, and that is why the Thompson Sisters -who grew up in the streets- chose to be his weapons. He is not one to simply stand witness to an unfair fight, because, god forbid, he would not be able to tolerate it. When met with an opponent incredibly strong, and put in a life-threatening situation, his primary concern is always Liz and Patty. For example, during the fight with Mosquito where his arm was amputated, Patty wanted to turn into her human-form to help him, but he ordered her not to because they would make her more vulnerable. Also, when Noah was about to absorb Kid into Eibon's book, his immediate reaction was not to save himself, but to throw Liz and Patty onto the floor so that they do not get absorbed as well. Kid is not one to show weakness to what he considers scum. He will put up a brave front all the way through, and even taunt his attacker despite the beating that will follow. For example, when Gopher was torturing the bound and helpless Kid, he kept smiling the whole time, commenting about how dismal the effort was. (Unfortunately, upon noticing Gopher's asymmetrical mouth, it is then that Kid starts to beg for someone to save him. )

He takes pride in being a Shinigami, feeling enraged and silencing anyone who speaks ill of his father and kind. Since he believes that collecting and eating souls not on Shinigami-sama's list is an unforgivable act, those who do so -he regards as repulsive scum. He, as a Shinigami, will never give others the freedom to kill as they so like. He feels that such scum do not deserve the right to be in charge of human souls, and he will punish them for intruding on Shinigami domain.

Not much is known about his past, but it is assumed that before entering Shibusen, he lived the life of a spoiled, wealthy child. The after-effect of being spoiled sometimes pokes its head out in his daily life. On top of being obsessed with symmetry, he is also obsessed with cleanliness -probably having servants to keep everything spotless in his own home. He does not like getting his clothing wet or dirty, nor does he like dusty environments. If the floor is muddy, he would rather cling on to a rock and ask to be carried than simply walk himself.
