“Never hate your enemies. It affects your judgment.”

“Even if you hate me, Zero...I will tame that beast in you...as many times as necessary. If you haven't completely lost your sanity...I won't let you die. Hate vampires, hate me...at least that means you haven't given up!" Yuki said to Zero. "How can I hate you?" Zero questioned Yuki.”

“One's character is set at an early age. The choices you make now will affect you for the rest of your life. I hate to see you swim out so far you can't swim back.”

“At the point so near to zero, just almost before the death, life’s value jumps to infinity!”

“And everywhere, infinite options, infinite possibilities. An infinity, and at the same time, zero. We try to scoop it all up in our hands, and what we get is a handful of zero. That's the city”
