Kingdom Hearts (manga)

The first series was based on Kingdom Hearts. It was released in four separate books and was translated to English by TOKYOPOP. This series differs from the others in a few ways: while the other manga were drawn and printed to read right-to-left, the first series was drawn and printed to read left-to-right; the chapters are also much shorter, usually only lasting six or seven pages of content; and there is an extra section at the end of each book (the first book featuring an art section, the second and third featuring 'Kingdom Bites' yonkoma, and the last book featuring an extra chapter set in 100-Acre Wood). The series was re-released in three volumes in Japan in December 2006 as "Kingdom Hearts: Final Mix".

Differences
this is more appropriate for the chapter articles The manga includes many changes from the game:
 * The manga includes a prologue which covers Sora and Kairi's first meeting.
 * There are no Keychains, and the only Keyblade Sora uses is the Kingdom Key.
 * Sora carries the Kingdom Key strapped to his back, rather than causing it to materialize when he needs it to fight.
 * In the manga, Sora is the one who finds Kairi, unlike in the video game, when he and Riku talk about the new girl that was at the mayor's house.
 * The story begins after Sora wakes up from his Awakening, and Tidus, Selphie, and Wakka are not shown.
 * The King's letter is written slightly different.
 * The night of the storm includes a scene at Riku's house.
 * Ansem, Seeker of Darkness's lines are slightly different.
 * Sora uses quotes from martial arts books to plan his boss strategies.
 * Sora's encounter with Leon and Yuffie is extended.
 * Aerith does not appear until Sora's second visit to Traverse Town.
 * Sora's meeting with the Dalmatians is not covered.
 * Rather than tossing the Keyblade back to Sora, Riku causes it to re-materialize in Sora's hands.
 * The destruction of Radiant Garden is covered with more detail, including a scene with Leon, Yuffie, and Aerith as children.
 * Aladdin uses his first wish to save Sora and his friends from a pit of quicksand, rather than to eliminate a swarm of Heartless. He uses his second wish to save Goofy, not Jasmine.
 * The Pot Centipede does not appear, and Maleficent takes Jasmine, rather than Riku.
 * Deep Jungle and Halloween Town do not appear in the manga, the former due to copyright laws.
 * In Atlantica, the Crystal Trident is never found or used.
 * The Lost Boys appear in Neverland.
 * Goofy finds the one Gummi Block they need in a Rock, Paper, Scissors fight with the Lost Boys.
 * Riku does not fight Sora after Sora reclaims the Keyblade from him in Hollow Bastion. After Donald Duck and Goofy defend him and Sora takes back the Keyblade, Riku sends out a wave of darkness to distract Sora and flees. After this, he meets Ansem.
 * Instead of Sora and his friends fighting Maleficent, she is consumed by her own darkness and vanishes when Riku/Ansem unlocks her heart with the Keyblade of People's Hearts.
 * Sora and company stay in Hollow Bastion on their first visit as the place becomes overrun by Heartless, as opposed to fleeing and coming back later.
 * Sora does not fight Riku under Ansem's possession. After they meet before the Keyhole, Riku/Ansem tells Sora that the Keyhole cannot be sealed with Sora's Keyblade until Kairi's heart is freed, and he gives Sora the Keyblade of People's Hearts to release her heart.
 * Sora does not battle Ansem at the End of the World. After confronting him at the remnants of Destiny Islands, Ansem destroys the island and Sora and his friends fall into darkness, where Ansem reveals the World of Chaos ship. Sora, Donald and Goofy then rush to the Door to Darkness to try and close it, when the light from Kingdom Hearts beyond the door destroys Ansem.
