Teru Mikami

Teru Mikami is a criminal prosecutor chosen as the Hand of Kira by Light Yagami. Considering Kira to be his God,Mikami is a devout Kira-worshiper. His answer to a Kira’s Kingdom question that asked what he thought of Kira was simply "God." His loyalty to Kira is exemplified when he forces himself to stop questioning Kira after he is perplexed by the task of creating and using a fake notebook. Aside from his disdain of "lazy people",Mikami shares the same view on crime as Kira,which is what made Light choose him to carry out judgments when he was put under surveillance.

Obtaining the Death Note:
Mikami takes ownership of Gelus' Death Note after Light falls under suspicion of being Kira again. He hired Hiroki Yudagawa to look into Misa and he follows her when she goes to dig up the Death Note that Light had buried. Yudagawa steals the Death Note from Misa before she touches it so Mikami unwittingly gains ownership when he pulls it from the box later. He immediately begins using the power to punish criminals. Light makes the connection between Misa's attack and Mikami. He sends Mikami apples for Ryuk and calls him,and Mikami gladly begins following Light's directive.

History of bullying:
As class president,he defended his classmates from bullies,often leading to physical altercations. Although Mikami was eventually successful in uniting his entire class against the bullies,he found his efforts making little headway once he began attending middle school. Constantly being bullied and beaten himself,Mikami's sense of justice became warped as he began to wish for the "deletion" of his "enemies." Worried about his safety,his mother attempted to convince him to give up trying to help his classmates. In response,Mikami lost faith in his mother and began to hold her in contempt. His mother would eventually be killed in a car accident along with four of Mikami's "enemies." Although Mikami initially mourned his mother’s death,he was content in the knowledge that his classroom became more "peaceful" as a result of the accident. Mikami also intervened when a group of young students bully one of their classmates.

Sense of justice:
As a child,Mikami's sense of justice developed through the over-observation of "his surroundings." Even at a young age,he had already begun categorizing people as either "good" or "evil." Raised by a single mother,she is described by Mikami as his only ally and sole confidant during his youth. His analytic behavior was indicative of his intellect which,coupled with his ambition and sense of justice,allowed him to become elected president of his class in elementary school. Mikami has a strong sense of justice that has developed over the course of his childhood. He detests crime and smilar 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." While Light is more interested in scaring criminals in order to prevent crime,Mikami is more interested in retribution.

Hikari Yagami:
Teru Mikami is revealed to be the guardian of Hikari Yagami,Light Yagami 's son. He is close to him as his ''adoptive father' since Light Yagami and Misa Amane's death. Being Mikami's adoptive son,Hikari has desires to learn about Mikami' s time as Kira and grows up wanting to become a Prosecutor like him one day. However,as time went by,Hikari became manipulative over Mikami,resulting in him having to kill his adopted son with the Death Note.
