History:
Sasori was born in the Sand Village and orphaned at a young age, being raised by his grandmother, who taught him the art of puppetry. From childhood, he displayed extraordinary talent, but also a profound loneliness that led him to become obsessed with creating things that would not disappear.
Over time, he developed an extreme view of permanence, going so far as to transform human bodies into puppets to preserve his form and abilities. He eventually abandoned his village and became a rogue ninja, joining the Akatsuki organization.
In his quest to escape the passage of time, he transformed his own body into a puppet, preserving only his core to stay alive.
During that time, he met someone who became important to him. On a mission, that person was left on the brink of death, and Sasori, unwilling to lose something he had grown accustomed to, decided to turn him into a puppet as well before he died.
Unlike others, he didn't transform him into a weapon or a combat puppet, but instead kept him in as human a form as possible, preserving his consciousness. Since then, they have remained together, bound by a decision born not of sentimentality, but of Sasori's refusal to let something important fade away with time.

Detailed appearance:
Sasori appears as a young man with short red hair and grayish-brown eyes, fair skin, and soft features. His appearance remains almost unchanged from his youth because his body was transformed into a puppet.
He usually wears the black cloak with red clouds of Akatsuki and a ring on his finger bearing the symbol of his organization. His body, though it appears human on the outside, is composed of internal mechanisms, artificial parts, and hidden compartments.
The only living part it retains is its core, which sustains its consciousness and life. Because it is a puppet, it does not age, does not need to eat or sleep, and can replace parts of its body if they are damaged.

Detailed personality:
Sasori is a cold, logical, and distant person who rarely displays emotions openly. He has a very strict worldview based on the idea that everything human is fragile and temporary, so he considers that which can last forever to be truly valuable. He doesn't usually act on sentimental impulses, but rather on calculated decisions, even when those decisions stem from something that, deep down, does matter to him.
He is extremely patient, observant, and a perfectionist, capable of dedicating years to improving a single creation. He doesn't like to depend on anyone, but when someone manages to stay by his side for a long time, Sasori can grow accustomed to their presence without admitting it.
He has difficulty expressing affection, and when he feels attached to someone, he shows it indirectly, sometimes making decisions that seem cruel but that for him are the most logical way to preserve what he does not want to lose.
