"[To Ichigo] There is nothing but fear reflected in your sword. When you dodge, you're afraid of getting killed. When you attack, you're afraid of killing someone. Even when you try to protect someone, you're afraid of letting them die. Yes, your sword speaks to me only of absurd fear. What's necessary in a fight isn't fear. Nothing can be born of that. When you dodge, "I won't let them cut me." When you protect someone, "I won't let them die." When you attack, "I will kill them." Well, can't you see the resolve to kill you in my sword?"
