358/2 Days is a Kingdom Hearts game for the Nintendo DS. It focuses mainly on the events that happened with Roxas during the time that Sora was asleep after the end of Chain of Memories. It will also introduce and explain the mysteries of a new 14th Organization member, Xion. There will be a lot more learned about the Organization, as well as the chance to play as them in the Battle Mode of 358/2 Days. The game was released in Japan on May 30 2009.
The story takes place in the Organization's headquarters, The World That Never Was and the other worlds in the universe of Kingdom Hearts. The Organization needs to gather Hearts from Heartless but the only way to do that is for Roxas to collect Hearts from the Heartless, since he is a keyblade master as Sora's Nobody. The game also introduces a new member of the Organization, named Xion. She can also wield the keyblade. The organization "made" her as a replica of Sora so they can get hearts faster. She eventually befriends Roxas, as well as Axel, but in the end, Roxas and Xion end up having to fight, with Roxas as the victor. After Xion's death, Roxas goes to the The World That Never Was to free Kingdom Hearts, due to a last request from Xion. This eventually concludes with Roxas having his epic battle with Riku, which ends up with Roxas' defeat. Soon after, Roxas is taken to the digital Twilight Town, with no memory of his past life but implanted with new memories of another life. Roxas runs to The Usual Spot, hoping to finally to go to the beach with his friends, kickstarting the events of Kingdom Hearts 2.
