Crisis Core: Final Fantasy VII/04: An Angel's Dream

This chapters starts in the Church of Sector 5. The walkthrough assumes that you did everything (so if you don't receive a mail when it's mentioned in the walkthrough for example, it's surely because you missed something).

Church
After the cutscene, make a separate save IMMEDIATLY, and do NOT walk on the flowers. You will need it if you don't manage to get the perfect date with Aerith. You will also gain access to new missions. Try to do at least the mission M7-2-1 in order to be able to add objects to materia fusion, M7-2-2 to receive the Keychain (you will be able to equip up to 3 accessories) and finally M7-2-5 to receive the Backpack (you will be able to equip up to 4 accessories). There is a chest in the northwest corner of the church. Then, either talk to Aerith or go to the exit.

Church Entrance
Just follow along and reach the next exit.

Street
Aerith will stop in front of the Market gate, leave her here and go to the north east talk to a little girl who will give you a new set of missions. In the meantime, you'll receive several mails.

Market
After Aerith leaves you, pay attention to this part, because you must not miss a single step! Make another separate save at the Save Point just in case. Then, go to the west to receive a mail. Finally, try to leave by the south exit. A cutscene will play and you will now have to talk to everyone listed on the map.
 * -Talk to each shop-owner (3)
 * -Talk to the little girl, and choose to wait 10 times until Zack moves by himself
 * -Talk to the little boy and give him 5 potions until Zack gives up
 * -Talk to Aerith again, and then, catch Bruno
 * -Propose to buy the medicine
 * -Go retrieve the wallet
 * -Make another separate save

The Perfume
It's now time to make some perfume! You will need to make the perfect fragrance 3 times in a row. The perfume lady is the one closest to the door to the Street. Talk to her to start the minigame. The rules are as follows:
 * The amount of oil needed will be different each time
 * The lady will drop oil until the player tells her to stop
 * Each drop has a value :
 * Drip : 1 drop
 * DripDrip : 2 drops
 * Splash! : 10 drops

If you succeed, the lady will tell you it's perfect, save again. Now, do it again 2 times. If you succeed, Aerith will tell you that she will "Cherish it forever". Now save again.

The Quiz
Now, go talk to the little boy near the door. This one is easier, you only need to win the big prize, and you can try as much as you want. Try to ask Aerith for advice and also pay for a hint before picking your guess. If the same number is said by Aerith and the boy, pick this one. If you succeed, you will receive a Hi-Potion.

The Race
Now, go talk to the man closest to the boy, he will ask you to retrieve 20 materia dropped on the floor as fast as possible. If you succeed, you will receive 100 gils.

The Perfect Date
Now, talk to the little girl again, she will give you a mission. It's now time to see if you're the perfect man for Aerith. Approach the last shop for a cutscene. Depending on what you did earlier, he will give you several items. Now more cutscenes, when you take control of Zack again, go back to the market then south. On your way, Bruno (the boy who stole your wallet), will stop you. If you managed to do everything right, he will tell you that you are the perfect man for Aerith and give you the materia Steal.

Sector 0 - highway
After a few fights, you'll get a cutscene.

Shinra Tower - 66th floor
Make a save at the Save Point. Then continue to the next room, in this room there will be two chests on each side of the elevator. Then take the elevator, before talking to Hôjô, grab the two chests in the back of the room and make a separate save.

Fusion Chamber
There are several things to do here before talking to Hôjô again (just don't tell him you're ready). Start with machine on the left of the map.

Left machine
You will have to face enemies with experimental materia, there is nothing more to say, it's a simple fight.

Center machine
Make a separate save before. After activating this machine, you will need to go down, then you will have 3 minutes to defeat each monster and retrieve their keys in order to open the cells (each cell contains an item). Don't forget to equip the Steal Materia beforehand (and also Thieves Gloves if you have them, you can get them in M7-4-2 or M9-3-5). Now defeat the 7 monsters (5 in the hallway, 2 in the cell room). Open all cells and grab the chests (3 in every cell) and return before the time is up.

Right machine
Save, then go the machine left of Hôjô, you will need to stop the machine at the right time when the countdown is at 0. It's a bit earlier than you would think, so try several times until you manage to get 100%.

Blue chamber
Save, then go towards the big blue chamber. Hôjô will then question you. For the right answers (according to Hôjô), you need to say this: You will receive up to 1,000 SP if you answered correctly, and also a bonus with either Sephiroth or Angeal in the DMW.
 * Sephiroth
 * Science & Tech
 * Does not fear

Talking to Hôjô
Now, if you're finished with the side stuff, talk to Hôjô and tell him you're ready. After the cutscene, there is a boss fight.

After the fight, the chapter will end.
