"If we acknowledge the existence of someone watching down on us from above, he would be impossible to catch...and I'd either be dead already, or forever be dancing in the palm of his hand."
"I suppose monsters. There are many types of monsters in this world. Monsters who will not show themselves and who cause trouble. Monsters who abduct children. Monsters who devour dreams. Monsters who suck blood, and monsters who always tell lies. Lying monsters are a real nuisance they are much more cunning than other monsters. They pose as humans even though they have no understanding of the human heart. They eat even though they have never experienced hunger. They study even though they have no interest in academics. They seek friendship even though they do not know how to love. If I were to encounter such a monster I would likely be eaten by it, because in truth I am that monster."
"I'm sorry. Everything I say is complete nonsense, so please, don't believe any of it."
"An eye for an eye, my friend."
"I just can't sit any other way than this. If I sit the way other people do, my reasoning ability drops by 40%."
“I want to believe Kira doesn't really exist that this is really divine judgement. But it's absurd to think that God would need a person's face and name to kill. This isn’t divine judgement by God. It's the actions of someone childish who thinks he's God. That's what this is.”
"That's true. Personal feelings shouldn't be involved."
"Do you remember how to kill?"
"Yes I do. You look it."
"Even if Light Yagami was Kira...Kira's power can only move by the will of the person who has it. Yagami, thank to you I feel 99% better."
"If you measured good and evil deeds by current laws, I would be responsible for many crimes. Figuring out difficult cases is my hobby. For me too it is simply prolonging something I enjoy doing. The same way you all like to solve mysteries and riddles, or clear videogames more quickly. And if it means being able to clear a case, I don't play fair, I'm a dishonest, cheating human being that hates losing. That's why I only take cases that pique my interest. It's not justice at all."
