Story
Roxas avoids the attacks of Dusk Nobodies in order to prove his endurance to Organization XIII.

Strategy
This mission takes place at in a small area known as The Hall of Empty Memories. Roxas's goal is to survive the attacks from Dusk Nobodies for one full minute. While it is possible to survive by simply Dodge Rolling or otherwise evading the Dusks for a full minute, it is possible even at this point in the game to destroy each of them before they decide to attack, and even if you don't kill the Dusk you can stagger it to prevent it from attacking. While more Dusks will appear to replace any that are destroyed, it is again possible to defeat them within the window between the Dusk appearing and deciding to strike.

If you decide not to attack, continuously Dodge roll from corner to corner of the platform. Feel free to heal if you are close to death.

On a related note, this mission is the most efficient way to fulfill Xigbar's requests for Roxas to defeat a certain amount of enemies with Limit Breaks and Final Limits. By that point of the game, your defense should be high enough that you could complete the mission by standing still, and your strength should be high enough that a Limit Break can kill up to five Dusks at a time. Make sure to disable any auto-Dodge Roll or auto-Block panels beforehand, though. Once you start the mission, simply stand still until the Dusks bring you to the Danger Zone, and then unleash your Limits.

Challenge Mission
On higher difficulties, this mission is practically impossible without an advanced Panel deck, and if you try it as soon as it is available, your only real advice is to stock Cure magic and rely on luck.

If you attack this Challenge at a later point in the game, it is much easier. Dodge Rush and Dodging Deflect are the best possible panels for this, as they allow you to automatically stagger or deflect the Dusks just be Dodge Rolling at them.
