"If you were to turn into a snake tomorrow and began devouring humans, and from the same mouth you devoured humans, you cried out to me, "I Love You!" Would I still be able to say "I Love You," the same way I do today?"

"Dammit, I'll show you who's more skilled with his language skills!"

"Let me tell you the truth. The truth behind fighting. Fighting continues forever. After you've defeated one person, someone stronger appears. If you manage to defeat him, then an even stronger person comes along. If you don't have the resolve to endure that eternal struggle, then eventually your confidence will erode. But it doesn't end there! The battle will continue elsewhere, fought by others. It's an endless cycle! And it doesn't end with a person's death. The cycle will continue! As long as people and their souls exist, there will be disputes and those disputes will lead to fights. And those fights will continue without limit, for all eternity."

"Back then. I felt a kernel of untruth in your words. You talked about "The world she loves" many times. But made not a single mention of "The world I love"."

"[to Szayel Aporro Grantz] Immaculate being... Was it? In this secular existence, perfection is an illusion, regardless of those who utter the contrary. This is the reality. Common man seeks it out, they strive to achieve it, as if it were some tangible thing... But... The fact of the matter is, perfection is a hollow shell. It is devoid of any substance. I spit on perfection. Perfection, after all, implies you've reached the summit. No trial and error, no ability to conceptualize. An omniscient being would have no need for such superfluous things... Am I making myself clear? For people who dabble in the sciences, such as ourselves, perfection would make us obsolete. Many magnificent things have been, and will continue to come into existence... And yet every last one of them will fall short of perfection's finish. Our function as men of science relies on their many shortcomings. Then, and only then, can we apply the fruits of our labor. To put it simply... As soon as you began spouting that nonsense about being an immaculate being... your fate was sealed. How dare you call yourself a man of science?"

"Kurosaki Ichigo, you have no chance of defeating me. Even if you somehow manage to defeat me, there will be three more powerful than myself for you to fight. It doesn't matter if you stand up again a thousand times. The road to victory does not exist."

"Only underlings get caught up in the matter of style and lose the battle. A captain can't afford such indulgences. Don't try to be a good kid. Whether you own somebody or they own you. The moment you start a fight, you are wrong in either way."
