From Kingdom Hearts II
] Are you angry? Do you hate me? Then take that rage, and direct it at the Heartless. Pitiful Heartless, mindlessly collecting hearts. And yet they know not the true power of what they hold. The rage of the Keyblade releases those hearts. They gather in darkness, masterless and free... until they weave together to make Kingdom Hearts. And when that time comes, we can truly, finally exist.
What in the world do you think you're prattling on about? Kingdom Hearts belongs to me! The heart of all kingdoms, the heart of all that lives. A dominion fit to be called Kingdom Hearts must be *my* dominion!
