About Death the kidAdd
Death the Kid commonly called "Kid" by his friends and family, is one of the main meisters that the series follows. He is Patti and Liz's meister and Shinigami-sama's son.
Kid suffers from obsessive-compulsive disorder, or OCD, which is manifested as an obsession over symmetry, otherwise known as asymmetriphobia. Things (and people) must be perfectly symmetrical, lest something unknown and awful happen. Thus if anything is off by any measurement
or a pose that is slightly out of place), he will try to correct it right away, even at the expense of the mission at hand. His favorite number is 8, not only for its symmetry, but for the fact it divides out evenly. He is so obsessed with symmetry that Kid refuses to fight a battle unless he has both Patty and Liz together, as he would be asymmetrical holding just one. The fact that the left half of Kid's bangs are marked with three white stripes causes him much stress. He has attempted to dye his hair all black to cover these asymmetric Sanzu Lines; however, due to his body being that of a Shinigami, it rejects the hair dye and soon returns to normal. The Index of the Book of Eibon referred to this obsession with order as the Madness of Law
He doesn't appear to have any problem socializing and genuinely cares for his friends. He is seen expressing concern about Soul's scar at one point, and also threatens Gopher that he will never forgive him if he hurts Maka.
It is mentioned by Maka that it is normally hard to match soul wavelengths with more than one weapon, but Kid as a skilled meister is able to do so since Liz, and Patti have a strong connection with each other and admiration for Kid who gave them a better life.
His father has mentioned that Kid is a shinigami and does not need to collect souls, but Kid says he wants to make a weapon of his own. His father also says that since he uses two weapons and the guns do not count as a set, he will have to collect twice as many souls: 198 evil kishin eggs and two witch souls instead of 99 souls and one witch soul.However,he seems perfectly fine with this.
