Місора Наомі

Naomi is a former "first rate" FBI agent who is engaged to Raye Penber. She is very intelligent, however she often lets her feelings get in the way of her investigative abilities.

Naomi is notable for having worked alongside L Lawlet in the past to solve the Los Angeles BB Serial Murder case, which was what initally helped launch Naomi's reputation within the FBI. Misora later left the FBI and became the fiancée of Penber. Misora and Penber plan to marry, move to the United States, and raise a family.

After Raye's abrupt death, she decides to search for his killer. She suspects that Kira was the last suspect Raye had followed and believes that Kira can kill people with methods other than heart attacks.
