Takagi (高木, Takagi) is a police inspector who appears in the manga pilot.

Plot
He, along with his superior, N-Suke Yamanaka, are to investigate Taro Kagami's school to find a connection between five students who died of heart attacks. Soon after, they interrogate Miura, since he was bullied by the bullies who died. After speaking with Miura, they go to Taro Kagami's house with the intent of questioning him, as he was also bullied by the students who mysteriously died of heart attacks.

Later, Yamanaka realizes the restlessness of Taro and begins to relate the events which have occured with a case that occured in 1978 or '79 (Takara Bank, Yamashita Branch) in which two people died of heart attack and other "accidental" deaths occured afterwards.

After the five students return to life, they go to Taro's school, to ask them questions about what happened the day they died, but when they went to answer, the five die again and Yamanaka and Takagi, too.

Later, Taro realizes it was Miura that killed them, using the Death Note and sends him off the names with the Death Eraser. They go to the Police Station to speak of the notebook, but they do not. When the boys test themselves, Yamanaka burning the notebook without knowing that there was another.

Trivia

 * When asked by N-Suke Yamanaka what he would do if he had the ability to wish anyone dead, Takagi replied that he would kill all people who were not good, proving to have a mindset quite similar to that of Light Yagami. However, Takagi makes no protests when Yamanaka declares that the Death Note must be destroyed.
 * It should be noted that "Takagi" is not this characters real name, as it is stated at the beginning of the pilot that all "victims" have had their names changed in order to protect their identity.

Quotes

 * “If I had that ability… …I’d kill all the people who I thought the world would be better off without. Then I’d create a world of peace with only those who had good hearts left.”
