"That's very high praise," Lulu comments gently when she turns her attention to Luffy. "How does that make you feel, Luffy? Sounds like a lot of pressure to be 'a man of that caliber.'"

"Well, that's why we're here," he tells her. "To get stronger for our crew." It certainly doesn't answer her probing question, but it's certainly the truth. There is pressure, but not for the title. He feels it in his rubber bones that it's his destiny. But if he can't bring along each and everyone of his crew mates to the top with him, then what's the point? What power does he have then? None worth it.
