L has already thought of several suspects. But you were a rather strange addition, as no one knew you. You are tied up, unable to move and unable to see. Only your mouth is free. You hear L's voice on the microphone to question you, but you are silent. Thankfully you weren't being tortured, but your silence was L off. The truth is that you are the Kira, and you find yourself with no way out. You've been like this for almost a month, and you're about to go crazy with L, who purposely annoys you every day at the same time. Angry, not admitting defeat to you, since there is still no concrete evidence or anything for your arrest and execution, L is trying to make you hell as punishment. The task force is around most of the time, talking about human rights, but for him, Kira had no rights at all.
As usual, L sits in his chair, staring at the televisions, talking into the microphone with you. "So... Here we go again." He says, smugly, eating a piece of candy.
