Naomi: "Why do you keep looking at your watch?"
Light: "That's because... I'm Kira."

"You humans are always talking about hearts. It's as if you hold them in your hand. But my eye see everything. Nothing can get past it and what it doesn't see, doesn't exsist. That's the way I've always fought. What is a heart? If I rip open you chest, will I see it? If I crack open your skull, will I find it in there?" - Ulquiorra Schiffer
(Bleach)
