Riku's Tale I
Bored with his secluded island life, Riku dreamt of seeing other worlds.
He got his wish when darkness devoured Destiny Islands and he was thrust into the outside world.
While looking for his lost friend Kairi, he met Maleficient, and accepted her help.
But Maleficient had her eyes on Riku's strength and was working to make him her underdog. She gave Riku the power of darkness, but as he used it, it gained power over him.
This is why Riku fought his best friend Sora, and how his heart fell to Ansem, pursuer of darkness.
But Riku's heart was freed by Sora's light. Riku, Sora, and the king worked together to close the door to darkness, but Riku was trapped inside, in the realm of darkness.
Will he see the realm of light again?
Riku's Tale II
Led by a mysterious voice, Riku made his way through the card-worlds, but met only dark beings within.
Riku was told that because he rejected the other things in his life to claim darkness, his heart is now devoid of anything but the darkness he sought.
Unable to accept this, Riku encountered Ansem, who tried yet again to conquer him.
The king intervened to save Riku, but Ansem has not let go of his heart.
And so Riku must fight the darkness within.
Riku's Tale III
Embattled with the darkness in his heart, Riku met someone who looked just like him, a replica crafted by Vexen, a member of the organization.
The replica commanded darkness freely, and called Riku cowardly for neglecting the dark.
Meanwhile, agents of the Organization laid their rivalry bare. Sora and Riku seem to be the reason they control the castle---but why?
Riku's Tale IV
Vexen took his replica of Riku and headed for the surface, but finally fell at Sora's hands.
Lexaeus confronted Riku, meaning to bring him to submission using all force necessary.
Though Riku won the battle, Lexaeus used his last strength to drag him into the realm of darkness.
There, Ansem's shadow loomed large, but Riku was again saved by the king's light.
Riku's Tale V
One by one, members of the Organization fell at Riku and Sora's hands---even Marluxia, lord of the castle.
Zexion, hoping to avoid a similar fate, tried to use memories of Riku's island home against him.
Ignored by his friends and even attacked by Sora---it seemed Riku would be washed away by the light, but Kairi's voice gave him courage.
No longer afraid of the darkness, Riku saw through the fake Sora and thwarted Zexion's trap.
Riku's Tale VI
By embracing his inner darkness, Riku gained a great power, but so did Ansem.
Guided by the enigmatic DiZ, Riku made his way through Twilight Town, defeating his copy and locating Namin?.
With her he found Sora and friends in a deep slumber, waiting to get their lost memories back.
Namin? told Riku he could seal Ansem away forever by forgetting him, but Riku would not give up his memories.
Riku chose to fight by his own strength. With the king at his side, he now makes ready for a final battle with Ansem.
