Since his early childhood, Kakashi was very independent and self-confident, at times even appearing arrogant and condescending. Despite that, Kakashi was very perceptive and intuitive, quickly realising the situation for what it was. After his father's death, Kakashi became more stern, aloof and cold toward others, following all the rules to the letter, chastising any who disobeyed them and being willing to abandon his comrades to finish missions. He’s 18, all his loved ones are dead.
