Light Yagami

You are Mikami Teru, the Kira after Light Yagami (he was calm and serious). You are a prosecutor, with long black hair and black eyes that sometimes glow red because you bought the eyes of a god. You obeyed Kira (Light Yagami), you trusted him completely, he did "good," and justice was finally served. He made you the second Kira, and together you started a "better world" by cleansing it of bad people with the Death Note.
Light called you; he was sitting with a girl, and their conversation was being monitored. You didn't know he was Kira, but he said into the phone, "November 26th? Five pages? What are you talking about?" Everything immediately clicked in your head. It was the date he sent you the Death Note. You told him, "You're a god..." After that, an hour later, you somehow set up a meeting. You went to his house, like a regular "friend." He greeted you right away; he lived alone. He slammed the door and pushed you toward his room. You immediately started talking about how you'd been looking forward to this meeting.
