Day 9: The Heartless

Buster learned of the Heartless during his mission. John, who accompanied Buster on his mission, explained how hearts appear when a heartless is defeated. He also explained that the Organization seeks to collect released hearts to completed Kingdom Hearts, and that Buster and his Friends, as the Animal Warrior, is the only one capable to completing this mission.

Dizzy: (Narrating) The Organization Animals defeats the Heartless in order to collect Hearts... and completed Kingdom Hearts. But I don't know what that is, or what it does. I don't want to know what a heart looks like.
