This is how Our Heroes are going to find Ansem in Ryan's Quest.
Crash: Whoa. Is that all that's left of the worlds taken by the Heartless?
Ryan: Those worlds will be restored if we defeat Ansem, right?
Sci-Ryan: That's right, Ryan.
Ryan: I mean... If we do defeat him, then all these worlds will be restored and disconnected, what's gonna happen to this place and to us?
Sci-Ryan: Well... um...
Matau: This is the Heartless world, so maybe it will disappear.
Bertram: But, not to worry. Even when this place go bye-bye, our hearts are not going anywhere. I am sure we can find our friends again.
He look at Meg's Lucky Charm
They went off to find him
Crash: I wonder where Ansem is?
Sci-Ryan: Dive into the most and dangerous place and we'll find him!
Ones born of the heart and darkness, devoid of hearts, ravage all worlds and bring desolation. Seize all hearts and consummate the great heart. All hearts to be one, one heart to encompass all. Realize the destiny: the realm of Kingdom Hearts. The great darkness sealed within the great heart. Progeny of darkness, come back to the eternal darkness. For the heart of light shall unseal the path. Seven hearts, one Keyhole, one key to the door. The door of darkness, tied by two keys. The door of darkness to seal the light. None shall pass but shadows, returning to the darkness. Ones born of the heart and darkness, hunger for every heart until the dark door opens.
They went down fighting a Chernabog and they defeated it, they went down and they saw a Door
Crash: What’s wrong?
Ryan: Don’t you hear something? There!
Voice: Careful. This is the last haven you’ll find here. Beyond, there is no light to protect you. But don’t be afraid. Your heart is the mightiest weapon of all. Remember, you are the one who will open the door to the light.
Sci-Ryan: I don’t hear anything.
Ryan: Strange... That voice was so familiar. Maybe it’s just my imagination.
Sci-Ryan: Maybe you’d better take a rest!
They went to the door
