Now you're on your own and you have to battle Zu, a form of a Garuda. Zu is a very easy. The reason why is that Lulu and Auron come later in the battle. After the battle, you have to look for the other people. Rikku is the last you'll find and she says you have to go to "Home" to find Yuna. To reach home, just follow Rikku or the red arrow like always.
