Mission 93: Believe

Mission 93 for Kingdom Hearts 358/2 Days is the last Mission in Roxas's storyline. On a quest to free Kingdom Hearts and reclaim Xion, Roxas is interrupted by Riku, who seeks the Keyblade master for his own accord. The dark enigma wishes for Sora's Nobody to come quietly, but he has other plans.

Mission Objective
Defeat Riku!

Story
Roxas must evade the Neoshadows Organization XIII sends after the Nobody to reclaim him. The renegade then battles Riku, as the dark warrior stands in his way on the quest to free Kingdom Hearts and reclaim Xion.

Strategy
This is the only Mission in Story Mode in which Roxas can Dual-Wield. Able to cut through Neoshadows like butter, the first group of Heartless should be no problem to destroy. Defeat the occasional duos of Purebloods that pop up for extra experience, but otherwise evade them and get to Memory's Skyscraper. Battle the scripted last batch of Neoshadows and prepare for the final battle of the game.

Once the battle with Riku starts, you will only be able to use the Oathkeeper (Riku took the Oblivion when Roxas threw it at him). Immediately run up to Memory's Skyscraper to obtain the Unity Badge. Utilizing the Glide ability, dodge Riku's fast strikes while getting in for a quick combo. Riku can easily be taken down with Event Horizon, as well as careful timing of the Guard (known as "Block" in Kingdom Hearts 358/2 Days) Ability.

If you are playing this battle with the Extreme Ring, Aero spells are your best bet against Riku. A stock of 20-30 Aero spells should allow you to take out Riku's HP, and if you miss with too many Aero spells, you should be able to finish him off with Event Horizon. The Neoshadows before the battle should be easy enough to get rid of, but when you fight the swarm, try activating Event Horizon, dashing away, and then reactivating it after jumping high in the air.

Challenge Mission
One must be extremely careful during this mission. Even a single swing to the air counts as a missed attack. Limit Breaks can miss, as they are not the standard attack, but be sure to halt pressing A after the Final Limit ends. A spell recommended for use is Thundaga when faced with a single far-away enemy.

The Zero Gear should be equipped for this mission with three Ability Units. Use Limit Breaks and Limit Recharges to cut down Riku as quickly as possible.
