Kingdom Hearts series (manga)

Kingdom Hearts is Shiro Amano's manga adaptation of the Kingdom Hearts series. Most of the Japanese volumes have been localized in English by TOKYOPOP and in German by Egmont Manga & Anime, but due to TOKYOPOP's loss of the license and later closure, the series has been indefinitely postponed in English markets. However, the series has since resumed publication after the license was purchased by Yen Press (North America).

Kingdom Hearts (manga) and Kingdom Hearts Final Mix (manga)
The first manga series is based on Kingdom Hearts. It was released in four volumes and was localized in English by TOKYOPOP. Unlike the other mangas, the first manga is read left to right, due to being serialized in the gaming magazine Famitsū PS2, rather than the comic magazine Gekkan Shōnen Gangan. In Japan, the series was later re-released from January to April 2007 as the three-volume Kingdom Hearts Final Mix manga, which was later localized overseas and consolidated into two volumes by Yen Press.

Kingdom Hearts: Chain of Memories (manga)
The second series is based on Kingdom Hearts: Chain of Memories. It was released in two volumes, and localized in English by TOKYOPOP and later compiled into one deluxe-sized volume with a new translation by Yen Press. It was also released in German by Egmont Manga & Anime. The Kingdom Hearts: Chain of Memories Manga has a much lighter tone than that of the game.

Kingdom Hearts II (manga)
The third series is based on Kingdom Hearts II. It was released in five volumes, then discontinued. The first two volumes were localized in English by TOKYOPOP, while all five volumes were localized in German by Egmont Manga & Anime. A sixth volume was slated to release on April 2012 in Germany, but was not published. However, Shiro Amano has stated that he plans to resume serialization of Kingdom Hearts II after Kingdom Hearts 358/2 Days's series ends. Kingdom Hearts II seems to take a more serious tone than Kingdom Hearts: Chain of Memories, but still has some humorous scenes.

Kingdom Hearts 358/2 Days (manga)
The fourth series is based on Kingdom Hearts 358/2 Days. It was released in five volumes, and was localized by Yen Press.
