sora opens the door to an area that resembles destiny islands. sora: is this... is this my island? sora’s group approaches the area where the secret area used to be. voice of ansem: this world has been connected. the objects on the islands start to disappear. goofy: what was that? voice of ansem: tied to the darkness...soon to be completely eclipsed. there is so very much to learn. the ocean turned purple. voice of ansem: you understand so little. a meaningless effort. one who knows nothing can understand nothing. the island changed and the camera shows riku’s powerful form. sora’s group approaches closer. ansem: take a look at this tiny place. to the heart seeking freedom this island is a prison surrounded by water. and so this boy sought to escape from his prison. he sought a way to cross over into other worlds. and he opened his heart to darkness. riku turned to ansem. sora: riku! ansem: don’t bother. your voice can no longer reach him where he is. his heart belongs again to darkness. all worlds begin in darkness, and all so end. the heart is no different. darkness sprouts within it, grows, consumes it. such is its nature. in the end, every heart returns to the darkness whence it came. ansem appeared in midair floating behind sora’s group. ansem: you see, darkness is the heart’s true essence. sora: that’s not true! the heart may be weak. and sometimes it may even give in. but i’ve learned that deep down, there’s a light that never goes out! ansem rises up a little. ansem: so, you have come this far and still you understand nothing. every light must fade, every heart return to darkness! group final fight is against ansem. after the first fight, the tree shakes apart revealing ansem where he is waiting. sora’s group enters that area, but donald duck and goofy were shoved back from the invisible barrier. only sora made it to that area. sora fights darkside and defeats it. then, sora fights ansem after he appeared for the second time. after the fight against ansem, sora’s group ends up in the dark emptiness.
sora: wha...? ansem: behold the endless abyss! within lies the heart of all worlds: kingdom hearts! the camera shows the white door, kingdom hearts. ansem: look as hard as you are able. you’ll not find even the smallest glimmer of light. from those dark depths are all hearts born. even yours. the world of chaos appeared. ansem: darkness conquers all worlds! suddenly, goofy and donald duck were sucked into a portal and sora falls, but then... voice of riku: giving up already? come on, sora. i thought you were stronger than that. sora flies up and saw ansem in his ultimate form, which is the world of chaos. sora’s final fight is once again none other than ansem. after the fight, ansem freezes himself with a heartless crest that protects him. sora saw a portal and goes in it. in there, sora destroys the room core and escapes from it. then, sora fights the artilleries. after defeating them all, a portal was reveal and sora goes through. inside, sora rescued goofy and destroyed the second room core. they both escaped. then, sora and goofy fights the face. after defeating it, another portal appeared. sora and goofy goes through it. sora and goofy rescues donald duck and they destroyed the third room core. sora’s group escaped from that area. sora’s group fights the main core. after destroying it, ansem revives. sora’s group fights ansem one last time. after sora’s group defeated the world of chaos, ansem is still alive. ansem: it is futile. the keyblade alone cannot seal the door to darkness. (to the kingdom hearts) kingdom hearts! fill me with the power of darkness... kingdom hearts’ doors open with dark smoke coming out. ansem: supreme darkness... sora: you’re wrong. i know now, without a doubt. kingdom hearts...is light! light appeared from kingdom hearts doors. the lights illuminate ansem. ansem: lights? but why...? ansem has disappeared for good. with kingdom hearts’ doors partially open, sora’s group approaches them and begins closing it. sora: come on! while sora’s group pushes the doors, goofy stopped to see something. donald: stop staring and keep pushing! suddenly, donald duck and goofy saw more heartless through the doors of kingdom hearts. donald & goofy: the heartless!? donald: hurry! sora: i can’t...
riku: don’t give up! riku appeared from the other side of the doors. riku: come on, sora! together, we can do it! sora: okay! sora’s group and riku tries harder to close the doors, but the heartless are approaching. donald: it’s hopeless! suddenly, the heartless was eliminated one by one. then, goofy and donald duck saw something bright coming out, it is mickey mouse. donald & goofy: your majesty! mickey: (holding his own keyblade) now, sora! let’s close this door for good! donald: (to sora) close it, quick! sora: but... mickey: don’t worry. there will always be a door to the light. goofy: sora, you can trust king mickey. riku: now! they’re coming! mickey: donald, goofy, thank you. sora’s group closes the doors. riku has one last thing to say to sora. riku: take care of her. sora nods as he and his group close the door. then, sora and mickey uses their keyblade to make kingdom hearts disappear. after that has been done, sora saw kairi, who is about to go back to her world. donald tried to follow sora, but goofy stopped donald before he could do anything. sora runs to kairi. we watch a final movie of sora coming to kairi. sora: kairi! kairi: sora! the area starts shaking. sora and kairi hold each other’s hand. sora: kairi. remember what you said before? i’m always with you, too. i’ll come back to you. i promise!
kairi: i know you will! s ora and kairi’s unable to grab each other’s hand any longer. once they’re let go of, kairi is separated. the ending theme song “simple and clean” performed by utada hikaru plays and the camera shows kairi being taken back to destiny islands. after seeing destiny islands turning back to normal, kairi enters the secret area to remember the scribbles she and sora did. when she saw the scribble of kairi and sora giving a star to her, sora appeared scribbling and looked at kairi smiled before he disappeared. kairi smiled and tears came out of her eyes. the camera then switches to the same scribbles, but this time, another paopu fruit was shown and given to sora. the credits roll. after the credits, the epilogue begins where sora’s group with donald duck and goofy in their original clothes started walking down the road. donald: well, now what do we do? sora: we’ve gotta find riku and king mickey. goofy: but, uh, where do we start lookin’ for that there door to the light? sora’s group looks down as if clueless. then, sora saw pluto appeared with something he’s holding in his mouth. donald: pluto? goofy: hey, pluto. where have you been? donald: (saw pluto’s mouth holding something) hey! goofy: gawrsh, that’s the king’s seal! sora: (to pluto) hey, have you seen king mickey? pluto leads the way by running. sora: guys, let’s go! sora’s group ran after pluto. while following pluto, sora smiles, donald duck, and goofy are enjoying themselves as they embark on the next adventure. mysterious voice: remember, sora. you are the one who will open the door to the light.
