Kazuichi So(u)da

 THIS CONTAINS SPOILERS FOR BREAKING KRYS 2 AND 3 

Appearance
He, being a mechanic, wears a bright green-yellow jumpsuit with a dark brown streak on the sides reaching his ankles. Kazuichi wears bright yellow sneakers as well.

Kazuichi's hair is dyed hot pink and is somewhat badly layered. However, he covers said bad layering up with the gray beanie he wears. In addition to his punk rock appearance, he has thin eyes with hot pink prescription color contacts on them at all times. Above his eyes, his thin, pronounced eyebrows nearly touch his hairline. His teeth are sharp, giving him an intimidating grin. He also has earrings, the right one having a plus sign as it is a screw with the plus head and the left one having a minus sign as it is also a screw but with the minus head.

Personality
Kazuichi is a highly emotional character, though he tries to play it smooth and acts carefree at first. He is a very jumpy person, easily scared and often screaming in fear. People tend to note his intimidating appearance does not match his compulsive and cowardly personality. Naturally, he has a great fear of dying on the island, which causes a lot of stress and panic for him.

Kazuichi has a tendency to neglect his need for a verbal filter and often blurts things out without thinking. He also seems to be a very bad liar, leading him to be contradictory at times. While he is a genius with machinery, he appears to be a bit slow-witted otherwise. Alongside Mikan Tsumiki, he is commonly Monokuma and Hiyoko Saionji's target and often ends up being the butt of their jokes.

Being the Ultimate Mechanic, Kazuichi normally tries to repair any broken items on the island with his ability and familiarity with mechanisms. He tends to carry around a wrench and he gets anxious if he cannot tinker with something. He has a great love for machinery, especially fast ones like rockets and bikes, which is ironic, since he suffers from awful motion sickness. Kazuichi seems to question his sexuality around Hajime Hinata, for example, in Island Mode, he was excited and then confused about going on a date with him and he's afraid he'll dream about a date with Hajime after he jokingly suggested going on one, only to comically confess to him that he is attracted to tanks. In Chapter 3, it's also revealed that he apparently likes the idea of undressing a girl and checking out her bone structure, thinking it's similar to dismantling machines. He seems to think it's normal, though Hajime is weirded out by this and calls it a fetish.

Kazuichi also likes girls a lot, though in a rather perverted and shallow way. He has taken a strong liking to Sonia Nevermind, to an extent of being a pervert, and in constant jealousy of Gundham Tanaka. He claims that he's dreamed of a beautiful blonde girlfriend since he was a kid and his affection towards Sonia seems rather shallow, as he actually seems to dislike some of her actual personality traits, such as her love for the occult. Sonia dislikes this behavior and calls him a stalker. According to Kazuichi, after he changed his appearance in the past, some girls took interest in him and he was actually a bit frightened by this.

Despite having some weird quirks, Kazuichi is described as the 'straight man' and is one of the more ordinary students in the group. In his Free Time Events, it's revealed that he suffers from self-esteem and trust issues. Due to a past friendship, he has a hard time trusting others and he acted especially paranoid during the beginning of the game. He also reveals his appearance was chosen for the sake of his image, not because he actually likes it. His trust issues cause him some conflict with Hajime, but he calms down quite soon and is willing to apologize. Despite some issues, he develops a close friendship with Hajime, and he considers him his "soul friend". However, Hajime can be quite annoyed with him, since he can act rather clingy and turns even whinier and threatens to bug Hajime even more if he refuses to hang out with him.

Backstory
Kazuichi's life seemed to have been fairly tougher than a normal child's. He and his father ran his family's bike shop, but nothing was ever sold. The bike shop wasn't always inactive, however, many customers would ask for them to fix their bike tires or inflate them. Despite this, the family was still often low on money. In result, though, Kazuichi got plenty of practice with making and building things.

Kazuichi liked to improve many things, such as his greatest invention, attaching an engine to the machine that draws the chalk lines on soccer fields. However, it escaped through the school entrance at full speed, without curving or stopping.

As a child, Kazuichi was also very skittish and easily picked on. He had a best friend in middle school. They always did everything together, and could he talk to him about anything. Once, Kazuichi let him cheat off his test because his friend had begged him for help, but they both got caught by the teacher. He insisted that Kazuichi was the one who willingly gave him the answers. Starting from that point, his friend began avoiding Kazuichi, though, in actuality, Kazuichi didn't really care about being scolded. However, because of this, Kazuichi later developed trust issues.

Kazuichi let other children step all over him, but then he decided to change his appearance entirely. From changing his hair color to losing his glasses, and presumably sharpening his teeth so that he could fit in better with people around him. It seems as if it'd do the opposite, but that may just be how his mind works. At this point, he began to put up the "tough punk" facade to avoid more bullying, which, to this day, continues to break almost constantly.

In addition to Kazuichi's rough childhood, with money and bullying problems, his dad seemed to have beat him at times. In one of his Free Time Events, he states that he had never been on a field trip, and spoke quite casually about his father beating him when he didn't attend school on those days. Such behavior suggests that he was a subject of excessive abuse.
