Crisis Core: Final Fantasy VII/02: Betrayal

Shinra Tower
After the few cutscenes you will be free to move around. Don't forget to read your mails and to go grab the free item outside of the Briefing Room (Thunder materia). Also, new missions are available.

Leave the Briefing Room for now and talk to Kunsel. He will take you to the streets of Sector 8, where you can begin on starting the Side Quests.

Sector 8
You start at the blue exclamation mark on the map, first, go south to talk to the 3 women and join their fan club (only two of them will offer you to join their fan club). Then go north, since there is nothing interesting to the east.

Loveless Street
Talk to the guard on the right to unlock a new mission (it's a Side Quest comprised of 6 missions, do them now if you want and go talk to him again), and then go to the north near the truck to receive a mail, then go to the alley talk to the woman to join her fan club. When you're done visiting, go back to Shinra Tower.

Shinra Tower
A woman will offer you a free drink, you can take it if you want. It will give you a Raise status, it's unlimited but not stackable, only one at a time. Then take the elevator to the SOLDIER Floor, and before heading back to the Briefing Room, visit the Materia Room. Here you will talk to a scientist and this will unlock a new mission. You can now go back to the Briefing Room to continue with the main story.

Briefing Room
After a short cutscene with Tseng, you will travel by helicopter to Banora.

Banora - apple orchard
There is a chest on your way that contains a Soma. Just after the Savepoint, there is a boss fight.

After the battle, loot the chest north that contains an X-Potion.

Banora
There are 5 chests in Banora that you will need to open later, those can be missed, so keep a save in another slot just in case. The chest next to Tseng doesn't count, but take it anyway, it contains a Hi-Potion. You'll get a tip when it's time to find those 5 chests. You will not be able to take them now, but at least interacting with them now is important for later, so be sure to find them all! The thing is, for now they're not under their "Chest form", so take a look at the orange spots on the map to know where to find the interactive spots. There is a chest to the right of the lonely house northeast of the fountain. When you're finished with chests and have found the 3 hidden spots, enter Angeal's House for a cutscene (it's the last one obviously).

Angeal's House
After the cutscene, grab the chest behind the table, it contains 5 Gils.

Banora
On your way to the factory, go interact with the orange spot before the road splits. Then take a right and, along the way, another chest that contains a Hi-Potion. On top of the cliff, you'll find a chest to your left, and the final orange spot in front of you. Now would be a good time to make a separate save because of the next events.
