"Ichigo...We can't...Watch any longer...Eachother's backs...I just can't...I just can't help you out anymore."

"My, my. So dangerous."

"There are two kinds of fights. As long as we place ourselves in battle, we must always know the difference, a fight to defend life or a fight to defend pride."

"Unless I grip the sword, I cannot protect you. While gripping the sword, I cannot embrace you."

"[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?"

"Every time you and I interact...a bit of "heart" is born between us. Heart isn't something inside you. But whenever you think, whenever you remember someone, that's when heart is born. I mean, if you were the only one alive in the whole world, heart wouldn't exist, now would it?"

"I am calm. That's why I can fight you!"
