A brand new announcement has been made about popular gaming series, "Kingdom Hearts."

Unfortunately, it is not the highly anticipated release date for "Kingdom Hearts 3."

Today it was confirmed that the "Kingdom Hearts Unchained X" release date for Japan will be sometime in September. Square Enix has begun pre-registrations for the game, which will be available on both the iOS and Android platforms.

Earlier this year at the 2015 E3 event, director Tetsuya Nomura explained several key points about "Kingdom Hearts Unchained X," including its placement in the franchise timeline.

"'Chi' and 'Unchained Chi' will officially be set before the Keyblade War on the official 'Kingdom Hearts' timeline. They both will lead into the Keyblade War," said Nomura (via KHInsider).

Nomura also explained that while "Chi" and "Unchained Chi" have very similar stories, there are differences that will be explained further.

"The story between 'Chi' and 'Unchained Chi' are very similar but there is a 'gimmick' of sorts between the two versions. We'll find out about the 'two different keys as the story is revealed," teased Nomura.

Despite the confirmation of the Japan release date, Square Enix has yet to confirm the release date for North America. Luckily, Square Enix did confirm the game would be exported to the West, so fans outside of Japan will likely get the game sometime after the Japanese release.

Anime News Network reports the following description for "Kingdom Hearts Unchained X":

"The game will take place in the distant past, and players will take on the role of a keyblade wielder. Players will strengthen their keyblades and collect character medals while investigating various Disney-themed worlds. Players can use the medals to launch big attacks, and create and use decks. Players will also aim for a 'one-turn finish' in battles."

For those who are not familiar with the "Kingdom Hearts," the series franchise is a Japanese RPG combining Square Enix and Disney characters. The games follow the story of Sora, who one day discovers that not only are there other worlds, but that his heart contains the key to saving them from the darkness.
