ralsei is able to exist in other dark worlds because he is the castle town darkner. every darkner can exist in castle town, so that means ralsei can exist in other dark worlds.

That theory is too lame and simple IMO. Boring explanation

And how do you suppose Ralsei got to the Cyber World? Cause he has the power to enter the Light World without becoming an object thanks to possessing a Lightner's SOUL.

either game logic or the great door.

You don't want Ralsei to have anything interesting about him? Cause there's gotta be some twist or he's a real basic character.
