Kyosuke Higuchi has slick but spiky brown hair and brown eyes and has an odd and insidious look on his face much of the time he's on screen. He's usually seen wearing a black suit with a dark white/light grey shirt underneath with a white tie. In Death Note: Kira Game, his appearance remains the same, but his hair is black instead.
Kyosuke Higuchi is the Head of Technology in Yotsuba Corporation and one of its eight high-ranking executive. He is chosen by Rem who gives him a Death Note, Light Yagami wanting a particularly selfish individual to possess it, thus becoming the third Kira. Rem orders him to continue the killing of criminals, then allows him to use the Death Note as he wish. Since then, Kyosuke meets every weeks with the rest of Yoshiba Group to choose a person to eliminate to augment their profits. The other members immediately understand one of them is Kira, but ignore is identity.
In one of these meetings, they are interrupted by Matsuda, who was searching for information. Matsuda manages to convinces them he is just Misa Amane's agent and wants a partnership with them. He even invites them at a party. There, L and the Task Force faked his death, preventing im from getting killed by Kyosuke. Later, Arayoshi Hatori, one of the groups's member, start wanting to leave, thinking they are compromised. He is then killed by Kyosuke, using the Death Note.
Rem then reveals Kyosuke's identity to Misa Amane. Misa seduces him then reveals to him she is the second Kira, and tricks him into confessing he is the third Kira, unaware of being recorded.
Meanwhile, L set up a plan to take down Kyosuke, with the help of some members of the group, who betrays him in exchange of immunity. They reveal to Kyosuke Matsuda is alive and going to reveal is identity to Sakura TV. Desperate, Kyosuke run to Sakura TV, accepting Shinigami Eyes from Rem and killing a cop, but is finally arrested by cops wearing blacks helmets led by Aisawa.
He attempts suicide but is prevented by Watari who disarmed in using a riffle from an helicopter. He reveals then the existence of Death Notes. Light manages to touch the Death Note, retrieving his memories, and discreetly uses a Death Note scrap hidden in his watch to kill Higuchi.
Kyosuke Higuchi is a morbid and disgusting individual. His only concern is that of his company and seeks to advance it throughout the business world by any means necessary. Because of his greedy nature, he's the perfect one to possess the Death Note while Light Yagami is imprisoned and has his memories erased as a means of eliminating L. As he uses the Death Note, he becomes determined to eliminate the competition and when Matsuda begins to threaten that, he breaks down and turns to desperate measures to ensure that he's killed, even making the Shinigami Eye Deal with Rem.
