You can easily finish the main game in a week, even if you play on the hardest difficulty available at all times and keep yourself set to level 1. If you really pick up the fighting system and read through cut-scenes quickly you could beat the main game in a single day.
But there's a lot you can do post-game, including the unlocking an extra scene in the ending. If you're a completionist you probably won't be able to cram enough playtime to 100% everything in a week.
