Kakashi is still fighting the aliens for the sake of his parents and friends, who surely live somewhere. Between Arikawa's kindness and Shiro's strictness, this carrot-and-stick policy makes him perplexed, but eventually he gets used to it. However, when Kakashi loses the reason for fighting, the situation suddenly changes.
