Byakuya is an arrogant young adult who originally saw himself to be more superior then the others due to being the heir to an extremely successful family business. He is extremely reluctant to admit to any mistakes he might have committed. He is often cold, blunt, and reserved, but he has a deviously manipulative tendency. Byakuya often expressed irritation from Toko Fukawa and Genocide Jack's obsessive behavior towards him, but he also often used it to his benefit by ordering them around.
