"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! 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... (Ep. 1)"

"Look around you, and all you will see are people the world would be better off without. (Ep. 1)"

"However gifted you are, you alone can't change the world. (L: Change the World)"

"As long as it doesn't kill me, college is a lot of fun. (Ep. 15)"

"I don't sit like this because I want to. I have to sit like this. You see, if I were to sit normally, my deductive skills would immediately be reduced by roughly 40%. (Ep. 10)"

"He who strikes first wins. (Ep. 10)"

"Kira is childish and he hates losing... I am also childish and I hate to lose. That's how I know. (Ep. 6)"

"I just find [phones] distracting. I can't stand when people's cell phones are ringing when I'm trying to talk. (Ep. 6)"

"Coincidence? No, too convenient. This can only mean that Kira has access to police information. It's obvious now, this is a direct challenge to me. (Ep. 3)"

"Naturally, I am very interested to know how you're able to commit these murders without being present... but I don't mind waiting a little bit longer. You can answer all of my questions when I catch you. Let's meet again soon, Kira. (Ep. 2)"
