Sora, Donald, and Goofy have defeated Ansem and restored the world. But
beyond the dark door--a door that had to be closed--Riku and King Mickey
remain. And so the trio sets off again on a journey to find Riku and the
king. As they progress through Castle Oblivion and encounter agents from
the mysterious Organization XIII on the way, Sora and his friends begin
losing their memories. What does it mean to hold something dear? And in
the end, what path will Sora choose?
