You will live with your new companion and train them to be whatever you want, go on adventures or do anything you want with them! Anima with pre-defined personalities will have a stronger sense of self, but be more resistant to training. With a blank slate anima, you will have to do more work to get them to what you want, but you will have complete control over who they are and what they know. After making an anima, you will be given your own workspace to train and get to know your anima.
