[At the gesture, Sora realizes that he hasn't made the wrong choice in letting Tenma come along with him. The sight causes him to smile widely.] Well, it's kind of like that. I use a weapon called the Keyblade, but... it's part of my heart, too.

[He extends his hand outward and suddenly the weapon in question appears there, a large key with a small chain hanging off of it.] It's specifically for fighting Heartless, so it works really well.
