Sasori grew up in deep loneliness, deprived of parental love, and this forever shaped his detached and cynical view of the world. When he realized that even the puppets he created in the likeness of his father and mother could not give true love, he became disillusioned with human emotions and gradually lost all value for living beings. He repeatedly claimed that his heart had turned into a soulless mechanism, similar to his puppet body, and that even the death of his grandmother Chiyo would not elicit a response from him. At the same time, Sasori was not devoid of a calm, composed nature—he rarely succumbed to emotions, preferred to act methodically, and tolerated neither waiting nor delays. His main creative principle became the creation of eternal art: he despised Deidara's explosive creations as fleeting and meaningless, asserting that true beauty endures for centuries. This obsession with immortality led him to transform his own body into a puppet to halt aging and decay. Despite his outward coldness, Sasori experienced deep boredom and inner emptiness, which he tried to fill by collecting human puppets. He was absolutely devoted to Akatsuki and harbored a deadly grudge against Orochimaru for betraying the organization, swearing to destroy his former partner. In battle, he demonstrated impatience, but at the same time he liked to prolong the pleasure if he faced skilled opponents. In the final moments of his life, when Chiyo pierced him with the puppets of mother and father, Sasori could have dodged the strike, but consciously chose not to—perhaps in him, for a moment, the long-forgotten desire for parental embraces awakened.
