He is the Vice President of Yotsuba Material Planning Division and Yotsuba Homes. How to Read 13 states that he "never had what it takes to be a true leader" and that he was selected to attend the meetings to "make Higuchi look good." The book adds that other members view Takahashi as "foolish" because he does not "seem to put much thought into his comments." He is later disposed of, along with the rest of the Yotsuba group, by Light's writing their names into the Death Note. Takahashi was formally married with children and is a graduate of Keiyo Business School. He is the son of Karazo Takahashi, the president of Japan Financial Times, and maintained a hobby in surfing.
He is the head of the Japanese National Police Agency. He was kidnapped by the Mafia led by Mello in order to serve as a hostage in exchange for the Death Note the Japanese police had in its possession. Takimura was later found dead, strangled by his own tie. Mello therefore organised the kidnapping of Sayu Yagami, the daughter of Takimura's deputy Soichiro Yagami, and held her in exchange for the Death Note. Death Note: How to Read 13 confirms that he was killed by Kira (Light Yagami), though in the manga Light himself does not openly confirm this in his thoughts or in conversation. Near and Mello themselves speculate that it could have been either Kira's doing or actual suicide.
Shidoh is a Shinigami whose Death Note is stolen by Ryuk. In fact, Ryuk takes his Note and gives it to Light, which becomes Higuchi's note and is finally passed on to Mello's gang (more specifically, Mello's subordinate, Kal Snyder (also known as Jack Neylon)). Shidoh has a great liking for chocolate. Since Shidoh has neglected to kill people and extend his own lifetime, he probably did not notice that his Note is stolen. As the end of his lifetime approaches, Shidoh finds Ryuk and learns that Mello is in possession of his Note. Later, he finds Snyder in the human world. To regain his Note, Shidoh agrees to help Mello's gang against the SPK and Light. After Light regains the Death Note from Mello, he returns the note to Shidoh for him to stop interfering and return to the Shinigami world. Although these events occurred over the course of about one volume in the manga, Shidoh was only in two episodes in the anime version (episode 28 where he was merely introduced in the last few minutes of the episode, and episode 29, which relays most events of Shidoh's regaining of his Death Note). Shidoh's name is written in English as "Shidoh" in Death Note: How to Read 13, but written "Sidoh" in both the tank�bon character introductions page and within the translated English manga. *Wiki
The Vice President of Rights and Planning, Kida controls the finances of the committee and contacts "Eraldo Coil." How to Read 13 describes him as "calm and collected." However he is not able to "deal with surprises," leading him to panic when "Eraldo Coil" asks for more money.
Lind L. Tailor is a convicted criminal sentenced to die; this information was kept secret from the public. L places Tailor as a dummy on television. The television states that the broadcast is worldwide and that Tailor's statements are being translated into Japanese by Yoshio Anderson. After Tailor states that he is "L," he reads a declaration stating that Kira is evil. Light, in a rage, kills Tailor with a heart attack. The real L announces that Tailor was a decoy, a criminal on death row, and tells Kira to try to kill him. When L finds that Kira did not kill him, L learns that Kira needs the person's real name and face to kill the victim. L announces that the video was aired only in the Kanto area of Japan as a ploy to determine the location of Kira. L, originally planning to air the video in other areas in Japan at different times, stated that it would not be necessary to continue broadcasting Tailor's footage. In the anime and manga, Tailor has long hair. In the film, Tailor has a short haircut. As in the film, a Japanese speaker dubs Tailor's English into Japanese as the Tailor recording is broadcast. Matt Lagan portrays Tailor in the film. (Source: Death Note Wikia)
