Guadosalam - Chateau Leblanc
Before heading to Guadosalam…
Make sure you clear O’aka’s debt now if you haven’t done so already. This doesn’t award any Story Completion Percent yet, but you’ll miss out on critical scenes later on if you don’t pay off his debts now.
It’s finally time to sneak into Chateau Leblanc with your Syndicate Uniforms. Approach the entrance and choose “Okay!” when given the option to change Yuna, Rikku, and Paine into their disguises. A sequence of cutscenes will play out once they gain access to the mansion.
Living Room
Once you’re back in control of Yuna, go through the double doors on the main floor and interact with Ormi and Logos near the stairs. They’ll send you up to give Leblanc a massage. Even for a game that’s odd at times, this part is especially… odd.
Private Quarters
The premise is simple: it’s like a game of Minesweeper, and your goal is to find the pink heart. What’s odd about this mini-game is that you want to fail your first attempt on purpose. Your performance decides which accessory the chest in the hidden passageway holds later. Succeed on the first try, and it will be a 
Gold Hairpin, which you can find again later in the game. Succeed on a second or later try, and it will be a 
Heady Perfume, which is unique and whose 
HP Stroll and MP Stroll abilities make it one of the best accessories available at this point.
With that in mind, on your first attempt, find a blue heart spot and keep selecting it until you fail the ‘Mission’ the first time. The reward for succeeding right away is a Gold Hairpin, a lackluster item that you’ll be able to get elsewhere. The prize for failing the first attempt and then succeeding is Heady Perfume, which is one of the few accessories you can obtain that provides the HP/MP Stroll effect.
When you see a green or a yellow heart, you know you’re getting close to the pink heart that provides 5 points. Obtain enough satisfaction, and you can move on past this interesting assignment.
Another short cutscene will take place as Leblanc falls asleep on the table. Exit her room and head back down to the dining room. Examine the doorway on the far left side of the room. Yuna will press a button revealing a secret passageway, and they are done with the Syndicate disguises.
Hidden Passageway
Enter the Hidden Passageway. It won’t take long before Ormi and some Syndicate team members will ambush you, but they’re extremely easy to defeat. Head down the passageway and save your game at the 
Save Sphere.
Just past the Save Sphere is a doorway you can go through, and inside that room is the treasure chest that contains your prize for the “Duty Calls” task (which should be a Heady Perfume). There’s nothing else in this room, so head back out into the hallway and head right.

Open the door at the end of this hallway and examine the sphere on the nightstand. You’ll score 
Crimson Sphere 10 after watching it, and then be ambushed by Logos and Ormi again. And, yet again, these two are extremely easy to defeat at this point. It seems like these two forgot to level up while Yuna, Rikku, and Paine have been gaining all of this EXP.
Exit the room, and continue following the hallway north. Turn left/west and jump up the ledge. Drop down into the hole on the other side, and you’ll be able to activate “Security Override 2.” Jump down into the next hole and activate “Security Override 3.”
Once both have been activated, jump out of the hole and continue left/west (towards the red arrow 
) towards the wall. A spike wall will activate once you get close enough to it. Run away from the wall towards the spot where the hallway splits into different paths again, and the team will be forced off the ledge down to the level below.
Next, activate “Security Override 1” on the wall to the right. Drop down off the wall and proceed again to where the spike wall spawned. You’ll already be able to see another switch on that wall.
Activate this last switch (“Security Door Manual Override”) to open the door, and then follow the red arrow one more time into the last room. A cutscene will play as soon as you enter this room, so unfortunately, you’re not going to be able to grab any of the treasure chests in here yet.
Chateau Leblanc - Hidden Passageway
LivingRoom
One last fight with Leblanc, Ormi, and Logos. This fight, like the previous ones against the Syndicate, does not require any complex strategy. They’re very easy to defeat.
Helpful Hint
It almost goes unnoticed because it happens as just a one-off battle against him, but Logos drops an incredibly helpful item after this fight called a Charm Bangle. You can use this item to prevent random enemy encounters on the battlefield as equipping it applies the No Encounters Auto-Ability.
While it is generally not recommended to use this item this early on in the game, because your characters definitely need the EXP to level up, it is something that you have in your toolkit now and something to be aware of.
After the battle, the Mission will end, and Leblanc will opt to team up her Syndicate with the Gullwings, as it turns out that they have a shared goal (along with Noojie-Woojie). You’ll receive the Reassembled Sphere key item and the 
Healing Light Garment Grid, and you’ll automatically wind up back on the Celsius after this last cutscene.
You’ll be given the option to save your game, and then you’re in for some scenes that take place on the Celsius (on the next page).
Checking the “Guadosalam - Chateau Leblanc Complete” box adds the Story Completion Percent for the automatic scenes in Guadosalam - Chateau Leblanc.
