Not quite the sequel to Kingdom Hearts 1, but is quite important, for its theme of "memories". This game takes place after Sora and Riku got seperated by the realm of darkness. As Sora moves onward in hopes of finding his friend, he is interrupted, by a person in all black clothing, taunting him to appear at Castle Oblivion. As Sora enters this strange castle, where each floor can contain a whole "fake" world, Sora's strength, will, and memories get tested. Not too far off, Riku trails behind Sora, unknowingly, and also is put to test, as the darkness that he was exposed to, slowly consumes him.
