Teru Mikami

Teru Mikami (魅上 照, Mikami Teru) is a criminal prosecutor chosen as the Hand of Kira by Light Yagami. Mikami takes ownership of Gelus's Death Note after Light falls under suspicion of being Kira again, and needs someone to act as Kira without being giving every order.

He also performs the Shinigami Eye Deal with Ryuk, granting him Shinigami Eyes. When Mikami's decisions reveal that he can follow the thoughts and ideals of the first Kira, Light wonders if Mikami will become much-needed help, or a new threat.

Mikami has a strong sense of justice that has developed over the course of his childhood. He detests crime and similar to Light, expresses a fervent passion for punishing evil. His sense of justice, however, has developed into a rather "black and white" understanding of people and he goes as far as to label everyone he meets as either good or evil. What Mikami has learned in childhood has also caused him to become obstinate about encouraging people to improve society, resulting in his disdain for "lazy people."

However, while Light and Mikami have very similar ideals, the gap is evident through Mikami killing people who merely had a criminal record, even if they still do not commit crimes. Light disagrees with this because of how contradictory it is to Kira's purpose of deterring people to commit future crimes, so while Light is more interested in scaring criminals in order to prevent crime, Mikami is more interested in retribution.
