When the group gets to Twilight Town, a cutscene involving Sora explaining a memory he had about Naminé commences. It seems as though this is the only memory Sora has left. The trio has to hurry before they eventually forget who they are. The Key of Beginnings Card is given to Sora, and the group must make their way to the glowing room on the map.
Boss Battle: Vexen (Part Two)
This time, Vexen is a lot less laughable. He has a more impressive list of higher-leveled Cards and combo attacks. His deck has a bunch of 8, 9, and 0 Cards, which make it very difficult to cast any sort of Summon successfully without him breaking the attack, leaving you open for a pounding.
Aside from what you already know about Vexen’s attack list, he can now form puddles underneath your feet that make it difficult to keep any sort of traction.
All this means little when you get right down to the art of war. Simplicity is key here, so repeat the same tactic from before by rolling behind his attacks and attacking the back of his blonde head until he goes down.
At the end of the fight you gain the Vexen Card. After the fight, a rather dark cutscene starts with Vexen hacking up a lung, crumpled up on the floor. In his agony, Vexen mentions a link between Naminé and Marluxia. Surprisingly, though, just before Vexen lets out the truth he is pummeled by an energy blast from Axel.
Axel’s main purpose is to eliminate Vexen, before he “talks to much”. Vexen pleads for his life in his cowardly fashion, but before he can reason with Axel, he is extinguished by the flick of Axel’s fingers. “Goodbye” is all Axel says and impressively dispatches Vexen with little to no effort. Sora is beside himself, but before he can get any answers, Axel is gone.
After Sora leaves Twilight Town, Organization members talk to Naminé about setting Sora up so that they can take over the Organization. Naminé looks quite defeated, while Axel appears to have an ounce of remorse for Sora’s fate.
When Sora sprints back to Castle Oblivion, he is met by Riku, who apparently has the same necklace from Naminé that Sora does. Riku becomes angered and challenges Sora to the third battle between friends.
Boss Battle: Riku (Part Three)
This fight is almost a carbon copy of the last fight with Riku. However it seems as though he is slightly weaker, or at least has not grown in strength as you have since the last fight between the two of you.
Dodge Roll your way around this guy, jumping in to use Sleights and combos, then jumping back out to dodge and heal.
Deliver enough damage and Riku will fall. After the fight, you receive a Mega Potion Card.
Riku runs off after the fight, dropping his good luck charm from Naminé. Sora picks it up, which causes the charm to turn into the next World Card—Destiny Islands. It seems that Riku’s charm was the fake after all.
Goofy and Donald are worried because Riku and Sora both seem to have the same memory. Sora does not like what he hears and abandons them. Meanwhile Naminé speaks with Axel and, in a surprising turn of events, Axel lets her go, saying that he will look the other way. “Make it count”, exclaims Axel, after Naminé runs out of the room. Axel feels a bit of compassion for Sora and Naminé and chuckles at the silliness of it all. It is time to enter Destiny Islands.
