"Watashi wa L-desu."

"You have lost, Light. Didn't I say in the beginning, when you die, the one who'll write your name down in a notebook will be me? That is the deal between the Shinigami and the first human to get their hands on the note in the human world. Once you enter prison, I don't know when you'll die. It's annoying to wait. Your life is already over. You'll die here."

— Ryuk · Death Note

"This world is rotten and those who are making it rot deserve to die. Someone has to do it, so why not me? Even if it means sacrificing my own mind and soul, it's worth it. Because the world... can't go on like this. I wonder... what if someone else had picked up this notebook? Is there anyone out there other than me who'd be willing to eliminate the vermin from the world? If I don't do it, then who will? That's just it: there's no one, but I can do it. In fact, I'm the only one who can. I'll do it. Using the death note, I'll change the world."

"If you can't beat the game, if you can't solve the puzzle, you're nothing but a loser."

"I've never considered finding that notebook and gaining that power a misfortune."

"I'm pleased to meet you at last, L Number Two."

"I understood that killing people was a crime. There was no other way! The world had to be fixed! A purpose given to me! Only I could do it. Who else could have done it, and come this far? Would they have kept going? The only one who can create a new world is me."
