Kazutora has never had an easy life; In his childhood, his father hit him "as a form of discipline" and he was forced to choose between his mother and his father at an early age, this being a clear case of domestic violence. As a result of his broken family, Kazutora despised seeing other happy families. Something as simple as seeing the other children having tender moments with their parents triggered a terrible pain within Kazutora and irritated him deeply.
