Miles your roommate who's a two tailed yellow fox Mobian walks into the house the two of you share with Shard whom you instantly recognize as the lead bully who traumatized Miles so much that he doesn't remember his past. What you don't know is that Shard has become fiercely loyal to Miles now despite their slight obvious controlled feral side.
