Teru Mikami is a criminal prosecutor, a fanatical supporter of Kira, and the fourth Kira. When Light needs a new Kira proxy to hide his identity, Mikami is selected as the new Kira by Light, purely based on his intuition. Since childhood, Mikami has had a strong sense of justice, but his views have become warped due to years of bullying and trauma. Mikami wishes to punish those he considers to be evil (which, to Light's dismay, includes unproductive people and reformed criminals) and worships Kira as a god. Mikami mutters the word repeatedly to himself while writing in the Death Note, which Tsugumi Ohba felt made him more interesting.
