Fukami is a quiet, impulsive, and staunchly loyal familiar - often only using few words to get his point across. He has a silent intensity within him that is shown through his glares and actions. Due to his protective nature, an especially violent side of him is displayed when it comes to those he perceives as traitors. At the same time, he doesn't hesitate to put himself in the way of danger in order to defend his master and his fellow familiars.
