Kyosuke Higuchi is one of villains of Death Note, an executive at the Yotsuba corporation and a member of the Yotsuba group, which ran it. He was also a self centered man who viewed people as tools to be manipulated. Higuchi continued killing criminals, but also killed those that would benefit Yotsuba. The other members of the Yotsuba group noticed this and began holding meetings to decide who should die, but they remained unaware of who was doing it, just that it was one of them. The pattern of the killings came to the attention of L and the Kira task force. L managed to have cameras and bugs placed in the group's conference room. They even had Misa sign on to be Yotsuba's spokesperson, so she could meet the members of the group and report on each one. Higuchi revealed to Rem that he planned on marrying Misa, like it or not, after he eliminated his competition and became rich. rem acted in Misa's defense, and touched her with a piece of the notebook, after which she informed Misa of her past while warning her about Higuchi. Misa then approached Higuchi and managed to get him to reveal his power, which cunningly recorded. This proved a boon to the task force, but they faced a new hurdle. The Japanese government decided it was best to leave Kira alone, and pressured the NPA to fire those who didn't quit the task force. All agreed to stay on except Aizawa, who had a wife and daughter to support. L and Light then set up a plan to capture Higuchi using other members of the Yotsuba group and a TV broadcast. The plan almost failed, but Aizawa saved the day with a well timed road block. Higuchi then revealed the existence of his notebook, and those who touched it could see Rem. It was given to L and Light, who regained his memories when he touched it and killed Higuchi with a needle, his own blood, and a piece of the notebook hidden in his watch this whole time. L then unchained Light, but still continued to suspect him. Light retrieved his other notebook, regained contact with Ryuk, and began his plans to get rid of those who stood in his way.
