Kingdom Hearts Charakter

How can I get King Mickey and Sora, in Kingdom Hearts 358/2 Days? I've heard about buying the "Soul of Sora", and "The Return of the King", in the Moogle shop, after I've played trough the Game. But i didn't found these Items in the Moogle Shop.
Can anyone help me? :)
PS: sorry for my bad English...

you have to finish the game first.. がんばって ;D

I finished the Game, nevertheless I can't buy these Items, to get Mickey and Sora.

There are actually different methods.For "Return of the King" to be unlocked, all missions must be completed. Further missions are unlocked after beating Day 358. Check the days marked with a "~"."Soul of Sora" requires every mission to be completed with a gold ranking.

My Problem is solved. Now I have the Cheats for these two Characters! Thanks for helping me! :)
