You now have control of Serah, Lightning’s sister. Head over to the door of your room. When you leave Serah’s room, you’ll come to your first “Live Trigger” event. You will be given the chance to pick any of four options (sometimes it will be less). You can choose whichever you like. Some answers are more correct than others but the rewards are generally just “adornments” which have no effect on stats. In some cases, if you go back and play a section again later on (through Time Reversal, more on that later), some options of the Live Trigger will be different allowing for more exploration of events. Adornments are clothes for monsters that you will tame later.
You will enter a larger living area and have to hop over the furniture on the ground by hitting B or O. Make your way to the front door of the building you are in which is called NORA House. When you get outside, you’ll be greeted with another Live Trigger. Make your choice and head outside. When the world returns to normal, Noel will meet up with Serah and give her a weapon.
Your first real battle starts now. You’ll have to fight some Meonekton and nekton. I recommend going for the nekton first. They are small and have far less health than the bigger enemies, allowing you to take them out quickly and limit the number of enemies attacking you. The Meonekton are bigger and tougher but you shouldn’t have too much trouble with them.
If you feel comfortable with doing a paradigm shift, hit the LB or L1 to bring up the list of Paradigms. For right now, I would switch to Slash and Burn because the Ravager roll is good at building up the chain gauge (upper right) and causing stagger. Most Nekton will die before that point but the bigger Meonekton will take additional damage and, after each additional hit, will be stunned for a short period. You will have plenty of time to master this but make sure you try to because paradigm shifts and the chain gauge become very important to combat strategy later on.
Once you’ve defeated this group, you’ll have to run around this area and kill the rest of the monsters. To start a battle with them, just run into them. Most of these battles should play out very similarly to the previous battle. Use this time to practice Paradigm shifting and building stagger. After the area is clear, you’ll have a proper meeting with Noel and then set off for the meteorite to the N.
