I have nothing to do with him,” L said. “To be completely accurate, I do not even know B. He is simply someone I am aware of. But none of this affects my judgment. Certainly, I was interested in this case, and began to investigate it because I knew who the killer was. But that did not alter the way I investigated it, or the manner in which my investigation proceeded. Naomi Misora, I cannot overlook evil. I cannot forgive it. It does not matter if I know the person who commits evil or not. I am only interested in justice.”“Only... in justice…” Misora gasped. “Then... nothing else matters?” “I wouldn’t say that, but it is not a priority.”“You won’t forgive any evil, no matter what the evil is?” “I wouldn’t say that, but it is not a priority.”“But...”Like a thirteen-year-old victim. “There are people who justice cannot save.” Like a thirteen-year old criminal. “And there are people who evil can save.”“There are. But even so,” L said, his tone not changing at all, as if gently admonishing Naomi Misora. “Justice has more power than anything else.”“Power? By power... you mean strength?”“No. I mean kindness.” He said it so easily.
