"Just watch me, L. I'll solve equations with my right hand and write names with my left. I'll take a potato chip... and eat it!" | "It seems like you're pretty skilled with your hands. I bet you're pretty popular with the girls, aren't you?" | "Skill has nothing to do with it. It's your looks that count. I'm guessing you're not that popular, are you?" | "Huh?"
"You're saying I can use the Death Note all I want and I won't be punished?" | "Let's just say this, you will feel the fear and pain known only to the humans who have used the Notebook. And when it's your time to die, It will fall on me to write your name in my Death Note."
"If you choose to hold the names of your worst criminals, I'll kill petty criminals or the innocent! I'm holding the whole world hostage. So, who's it gonna be! I'm not the evil one here. But, all those who oppose me by hiding criminals, you're truly evil!" That's exactly how Kira thinks."
"Light, I'm gonna let you in on a little secret. What makes a shinigami and a human who has a death note different? Well, there are two things. And why do shinigami have to write the names of humans in their death notes? You got any ideas?" | "Of course not. Why would I know that? You know, you sure are talkative today." | "It's because we are able to take human lifespans for ourselves." | "Huh? Wait. What do you mean by that?" | "Let's say you have a human who is due to live until the age of sixty, and a god of death wrote that this person would die at forty. Sixty minus forty equals twenty. Now those twenty years taken from someone in the human world are added to that god of death's life so, it means that as long as we don't slack off - even if someone was to shoot us in the head or stab us in the heart with a knife - a god of death can not die. On the other hand, no matter how many names YOU write in your death note, your lifespan will not increase. That is the first difference between gods of death and humans who possess a death note."
"I can't believe how easy was to purchase this information. The world sure is a scary place." | "Why can't I see my own lifespan even though I have Shinigami eyes? Do you think you could tell me again?" | "Humans with shinigami eyes only need to know the lifespan of their victims. And just as we can't see the lifespan of others of our kind, humans who possess a Death Note cannot see each other's lifespan even with the eyes."
