He is Patty and Liz's meister and the Shinigami's son. He is called Kid by his friends and family. He suffers from obsessive-compulsive disorder, which is represented as a complete obsession about everything being symmetrical and takes the idea of perfection to the extremes. To him, anything symmetrical is beautiful and if it is off by any measurement (a picture frame off by millimeter, or a pose that is slightly out of place), he will try to correct it right away, even if the situation calls for utmost attention. The biggest problem Kid has with is his hair one side being completely black while the other has three white strips going across it. Showing Kid anything that is too asymmetrical or mentioning his hair will send him into a state of massive depression (which normally takes encouragement from Patty and Liz to break). In the most extreme of cases, Kid will cough up blood and faint; this is usually set off by his hair being cut, or completely failing to make something symmetrical.
He refers to Shinigami as 'honorable father' (chichiue). 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 (the guns do not count as a set), he will have to collect twice as many souls (198 evil human souls and two witch souls). It is mentioned by Maka that it is normally hard to match soul wavelengths with more than one weapon, but Kid is able to do so because he, Liz, and Patty have a mutual admiration for each other. Kid admires Patty and Liz's positive souls due to his negative personality. If he sees anything perfect or symmetrical get broken or destroyed, it will send him into a blind rage where he will unload all of his power to erase the offensive sight from his eyes. He has a flight-capable skateboard called Beelzebub, which he uses as a form of short distance transportation, though it could be used for long distance as well, as seen to be used for flying to Egypt. His favorite number is eight because of its symmetry.
As he was born a Shinigami, Kid's potential power is technically far above that of his fellow Shibusen students. However, the details of Kid's, or his father's, nature as Shinigami have not been revealed. Both share a skull motif (in Shinigami's mask and Kid's rings) and dark, vaguely monstrous, shadows appear around them when either use their abilities, such as Shinigami attacking Asura and Kid using Soul Resonance. Mosquito has stated that Kid has type D blood.
AttacksKid fights using a form of Gun-Kata, though, for some reason, he usually holds the guns upside-down (while pulling the triggers with his pinkies). Also, he will not fight until he has both Liz and Patty with him so the style is symmetrical.
*
Death God Martial Art, Stance of Sin: This fighting style is Kid's normal style but without using Liz and Patty and therefore focuses on chops, kicks, and hammer blows (all of which can be symmetrical). He also adopts the stance before fighting Chrona and Ragnarok.
*
Death Ride: Not really an attack it is Kid doing a rail slide with his skateboard.
*
Dark Needle: A seldom seen attack of Kid's that one of his most powerful. A giant black blast that leaves behind a series of skull-shaped smoke.
*
Tornado Flip: Kid launches his skateboard, spinning, at an opponent possibly cutting them in half. Not much is known as it was only used to save Patty and Liz once when they were being constricted by the Pharaoh of Wrath.
*
Death Cannon: Kid's Soul Resonance attack. When activated, Kid's lower arms are covered with metal and resemble cannon barrels. Three black spikes come out of each of the upper arms. He then charges his attack and fires two giant blasts of energy from the cannons that impact with the opponent, leaving behind a series of skull shaped smoke.
