Kingdom Hearts question!!?

Well, it starts off with a boy named Sora on his island with his friends Riku and Kairi. They are building a ship to get off of that island and explore. While that is happenning, Donald Duck (yes the one from disney, this story has to do a lot with the disney world) goes to see his majesty, the king mickey but instead he finds pluto (his dog) with a letter. After donald reads the letter he informs queen minnie and daisy as well as goofy. The letter said that the stars have been going out (every star is a world so that means worlds are being destroyed) and that the king went to see what's been going on. Donald and goofy go to another world to find the help that the king wanted them to find. More specifically, Leon, Yuffie, Cloud, and Aerith (this game also has a lot to do with final fantasy) The letter also said to find the keyblade master if possible. Then back on the island with Sora a storm comes and Sora goes to the island to save the boats. All these black thingies appear which isn't good. Later he finds Riku and then gets the weapon known as the keyblade which he can use to fight. He also finds Kairi but she suddenly phases through him and Sora must battle a giant black thing. After that he is warped to another world and his island is destroyed. Donald and Goofy just then landed in Traverse Town (the place they need to be at) and start searching for help. Sora then finds Leon and Leon defeats him and brings him back to a hotel room. Leon tells Sora that he is the legendary keyblade weilder and that those black thingies are heartless. Meanwhile heartless start popping around Traverse Town (there are many types of heartless) which ends up to Sora finding Donald and Goofy. They form a trio and travel the worlds helping people and then they finally find Riku, Sora's old friend and they have a battle. Riku has been taken over by darkness and then he dissappears. Kairi is also brought back to life. After that they travel to the final world and defeat the last enemy, Ansem, after that Sora, Donald, and Goofy find the King and riku and they all close the door to kingdom hearts. After that Sora and Donald and Goofy go to Castle Oblivion where the higher they go, the more memories they lose. Then Kairi in his memories is replaced with a different girl known as Namine (haha ironic isn't it). Then to regain his lost memories, Sora sleeps in a pod for a year in which after that starts Kingdom Hearts 2. This is where Roxas comes in. He is sora's nobody from when Sora killed himself to save Kairi. A nobody is when someone dies and the shell of their body becomes a nobody if they have a strong will. If their will is really really strong, then their nobody will look just like the person. Anyway, Roxas has had his memories changed so he thinks he is in some happy wonderland town called Twilight Town. He soon finds out that he is a nobody of Sora (often referred to as halves. One is the half of the other) Sora wakes up and travels the world much more defeating the main enemy, organization 13. At the end he comes to the organization's base world and defeats the final enemy. He also once more finds riku and the king.
