|Relatives||Heath Kazama Flick (father, deceased)|
Erika (adopted sister, deceased)
|Affiliation||Royal Investigation Service|
Initially, Keith gives the impression of a lazy genius, however he is able to accurately calculate and predict his target's intentions and next moves, and then moves in advance.
Keith is also skilled in math to the point that he is able to create portraits out of math formulas. He can also be obsessed such as when he filled his entire room with his equations.
Keith is short-tempered and prefers his privacy. Even though he has a habit of running off by himself during a case, he knows when he needs help although he always has trouble asking for it. He also likes Chicken Gumbo, a particular dish that uses weird spices from Hols Island.
He was deeply traumatized when his adopted sister Erika was killed, and now seeks to get justice against her killer.
Keith has green eyes and brown shaggy hair. He wears glasses and has a scar running from the bridge of his nose and under his right eye.
Keith cuts his hair shorter and shaves after his transfer to RIS, but then reverts back after the Erika Flick case is over.
Heath Kazama Flick is Keith's father. From what can be seen during the series, the two shared a friendly father/son relationship, with Keith even showing respect for his father.
Erika is Keith's adopted younger sister. They were apparently close when she was alive, with Gilbert Ross suggesting that Erika had feelings for Keith.
Keith was deeply traumatized when his sister was murdered and became obsessed with finding her killer. He eventually gets over her death when he takes down her killer, Gilbert Ross.
Keith and Gilbert have been friends for a very long time. They understand each other pretty well and Keith describes their relationship where "Gilbert creates puzzles and he solves them."
At the start of the series, Keith suspected that Gilbert was his sister's killer, but still acted like usual with him. Their friendship turns antagonistic when Keith starts actively pursuing Gilbert as a suspect in Erika's murder and Gilbert in turns seeks to have Keith kill him, so that Gilbert can escape his painful existence and be reborn in Keith's memories.
Keith and Koku's fates are both tied together due to a certain event. When Keith was younger, he deciphered and solved mystery of Jet Black Epitaph which allowed his father, Heath Kazama Flick, to create Koku. After Professor Kazama is killed during the attack on the Jaula Blanca Research Institute, Heath's notebook finds its way back to Keith who uses it to track down Koku to Cremona.
At the beginning of the series, Keith is actively trying to find Killer B (who he knows is Koku) to get his help on resolving his sister's murder. After Jean's murder, Koku saves Keith from being arrested and Keith in turns offers to give him information regarding Yuna, if he meets him at Heianji Temple. When they meet at Heianji Temple, Keith earns Koku's trust by revealing everything that he knows about Jaula Blanca and the experiments conducted there, as well as by saving his life from Minatsuki.
After the two (Koku and Keith) go into hiding, the two form a mentor/student bond with Keith acting as Koku's mentor and informant. When Lily discovers the pair, Keith tells her that Koku is his lost brother, but eventually tells her the truth. After Keith tells Koku about where he can find Yuna and how to get there, Keith and Koku work independently to take down the ringleaders of Market Maker for the duration of the case.
After the case is over, Keith allows Koku and Yuna to live with him.
When Keith first met Lily, he noticed a distinct resemblance to not only his adopted sister Erika, but to himself too. Noticing the resemblance, Keith opts to keep Lily at a distance, partially because he thought she was annoying and partially because he didn't want to get close out of fear of putting her in danger.
As they continued working together, Keith develops an appreciation of her skills, even though he still finds her pushy and annoying.
Keith is an Scottish male name that means "large woods or forests."
While Kazama is a Japanese name that means "Wind or while the wind is blowing."
