Garif Warrior is in ythe Ozmone plains. Random spawn it seems like in the area that is full of the Wu. Don't know the name of it off hand so I will describe how to get there. From the Garif Village, go to the north. Then you can either go east or northwest from this zone, go to the east. This is the zone that has about 10-12 Wu in it and two Happy Bunny's in the north. Sometimes a Garif Warrior will spawn here too. He will be neutral until you attack but he will also attack the Wu in the area.
