Luna again, providing you with the final summary of the non platform games,

Kingdom Hearts: Coded

Now, before we begin, i would like to say, that although just a cell phone game at the start, Coded was actually very complex. In my opinion, the story from coded was the most complicated to follow having not actually played the game myself (lacking a Japanese cell phone), as there is a mass amount of switching between the data world and the real world, and there was conflict between data characters, real characters, etc. However, the general points of the game, that is, the things you need to understand for the series, are all present. Keep in mind as you real that I actually had a difficult time describing this game, but I feel you will be able to discern the information necessary regarding the series as a whole.

OK, here we go:

Kingdom Hearts: Coded

Coded, originally released for the Japanese mobile phone, now translated to the NA Nintendo DS platform, takes place after the events of Kingdom Hearts two, when Sora has returned to the islands, and Donald, Goofy, King Mickey, and Jiminy Cricket are all back in Disney Castle. Jiminy Cricket is the source of the start of the game, when he begins to grow increasingly curious about the line “Thank Namine” which we all know he wrote before Namine restored their memories after Chain of Memories, resulting in the loss of the memory regarding that line. While sorting the information from all of his travels alongside Sora, Jiminy stumbles across a message he did not compose in his journal, something that both frightens and mystifies him. The message reads: “We must return to free them from their torment.”

King Mickey is also curious about this message, and in order to further investigate both its origin and its meaning, the King essentially creates digital copies of Jiminy’s journal and all its contents, including Sora himself. King Mickey travels inside this data version of Jiminy’s journal, where he in fact discovers the digital version of Sora. It’s a concept fairly similar to the Tron world of KH2, in which Sora, Donald, and Goofy digitize themselves to go inside Tron’s computer. Mickey creates a digital version of the journal, and goes inside himself.  During the Game, Sora is dressed in his attire from the first game, and the travels consist of certain worlds from the first game, having been created from the early entries of Jiminy’s journal.

Sora (the digital version) wakes on his home land of Destiny Islands, and much like the first game, when his home was swallowed by the heartless; Sora finds his home under attack by red and black blocks known as “Bugs” which to me are similar to a computer virus. Sora destroys these bugs, setting the pace for the rest of the worlds as he must do the same for each world the real Sora visited outside of Jiminy’s journal.

As data Sora goes about his travels, he encounters a mysterious cloaked figure, who is late revealed to be a physical manifestation of Jiminy’s journal, who is taking the form of Riku whilst inside the data world. The Journal explains to everyone that they are no longer in the real world, but in a data copy of it. The journal also tells data Sora, that it is up to him to discover his true identity in order to solve the mystery of the note, and save certain people.

Down the road, the company is interrupted by Pete and Maleficent who’s real world counterparts have traveled into their data world to wreak havoc. Maleficent uses her powers to destroyed Data Sora’s keyblade leaving him helpless as she summons a slew of heartless to defeat him forever and stop his plans from coming to fruition. The Journal and King Mickey interrupt his demise, and save Sora. Maleficent reveals however, that it was only a trap, and that her real target was the journal himself (who still looks and acts like Riku because of the Riku that Jiminy Documented). Maleficent leaves with the Journal, and Mickey and Sora give chase, finishing off their travels through the various Disney worlds until they end in Hollow Bastion. 

Upon arriving, they are greeted by Pete, who summons a now infected Journal to fight them (infected by the same bugs that were harming the worlds, which Pete and Maleficent have gained control of). The Journal cannot control himself/itself, and it attacks Sora, who is forced to defeat him, leaving him unconscious, but alive. Mickey then hits Sora with a grim truth; unless each and every bug is destroyed, the Journal will never awaken, and will be left in the comatose state inside the data world forever. Sora decides he must save him, and therefore continues to fight bugs, by entering the real Riku’s data world, to visit the worlds that the real Riku did, much as Data Sora had been doing for his own self.  It is at this time, where Mickey learns that once he and Sora finish the contents of the Journal as Jiminy wrote it during their adventures (in other words, once they reach the last world) that the Journal who looks like Riku, that is, the data manifestation, will have to be erased from the inside world.

While traversing Riku’s data world this time, they visit many of the worlds Riku had been to in his travels, and again, end up in Hollow Bastion. While traveling across the worlds, Mickey learns that his time in the data world is almost up, and that he will soon be forced back to the real world. Sora states that he needs more time, because the real Pete and Maleficent are still trapped inside he data world, unable to break free, plus, the Journal has not yet been recovered, AND they still haven’t learned of the cryptic message’s real meaning.  

Sora finds Pete and Maleficent doing battle with Sora’s heartless, and through this fight, it is revealed that Sora’s heartless was in fact the spawn of the Bugs troubling the worlds. Sora and Sora’s heartless do battle soon after Pete and Maleficent are erased from fighting. During this fight, Mickey returns to the real world, where he erases the Journal.  Mickey then fears for Data Sora’s existence, and travels back into the data world to see if he is safe.

Mickey finds Sora in Traverse Town. In order to complete their quest, Mickey takes Sora to the data version of Castle Oblivion, where they find a short man in and Organization Coat. The figure warns Sora of falling prey to looming sadness as he travels throughout the worlds, and says that if he allows the sadness of having forgotten his friends to consume him, then he will be consumed by the darkness (a sort of shout-out to the fact that everyone has returned to their respective homes in the real world, and are no longer together). Sora ignores this figures word, and begins a battle with him. Through this battle, the figured is revealed to be Roxas, at least, a data version of him.

Roxas loses the fight, and gives Sora a world card, much like is done in Chain of Memories after and Organization fight. Sora uses this card to open the door in front of him. After entering the door, Sora finds Namine, who reveals that the bugs as well as Sora’s heartless have been created in an unintentional side effect in restoring Sora’s memories from before Kingdom Hearts Two. She then reveals the information that the Journal had wanted him to find over his quest, and Namine tells Sora that he is “The Key That Connects Everything”, because he is tied to Xion, Roxas, Namine, Axel, Terra, Aqua, and Ventus, as well as the other main characters like Mickey, Donald, Goofy, Kairi and Riku. Finally, she reveals to him that she placed the message in his journal, (the data Namine wrote it there from inside) and states that the “Them” referred to in the message are Aqua, Ventus, and Terra, who are all trapped in separate ways, and needs Sora’s help to save them from peril. Mickey, the understanding that he must warn the real Sora, bids farewell to his data counterpart and leaves.

Mickey, back in the real world, writes a very famous letter to Sora, and sends it in a bottle. The message states what Namine had told them in the data world, and tells Sora, (the real Sora, who is reading on Destiny Islands with Riku and Kairi) that he must save everyone connected to his heart, thus beginning the next adventure, which will take place, In Kingdom Hearts Three.
