Mission 91 in Kingdom Hearts 358/2 Days involves Roxas trying to escape from the Castle That Never Was in The World That Never Was.

Summary
Escape the castle!

Story summary
Curious about his past, Roxas attempts to leave the Organization. To do so, however, he must escape the Castle That Never Was.

Mission walkthrough
Escaping The Castle That Never Was is very easy, as the path is very linear and easy to follow. Follow the path down and dispatch the Dusks you encounter. To reach the Ordeal Blazon in Naught's Skyway, jump from the top of the dual ramp and glide over to it. After taking the elevator at Crooked Ascension, head south through Nothing's Call. Samurais are along this path, but are easily eliminated with a weapon that boosts strength, such as the Ultimate Gear+. Continue south to meet Saïx.

Challenge Mission
This mission proves unchallenging until the player reaches Saïx. It is best to stay as far as possible from Saïx during the battle, especially when he goes into berserk mode. Glide is essential to escape his wrath. As far as battle strategy, load up as much Thundaga magic as is manageable, and attack repeatedly from a distance. It may be a good idea to bring an Elixir or two. In addition, make sure to have a keyblade equipped with a high Magic stat. Also, while it is near suicidal to attempt to attack Saïx when he is in berserk mode, it is possible, on occasion, to sneak in a combo after he calms.
