Chiyo

チヨ

Chiyo is Sasori’s grandmother and Ebizo’s sister. She was formerly a powerful shinobi of the Hidden Sand Village, though she has since retired. As a founder of the Sand Village’s puppet division, she trained numerous disciples and developed new puppets. Chiyo also sealed the One-Tailed Shukaku inside Gaara, acting on the orders of the Fourth Kazekage. In addition to being a puppet master, she was a skilled poison maker. However, during the last Great Ninja War, she was humiliated when Tsunade of Konoha devised antidotes for every one of her poisons. Consequently, Chiyo holds a grudge against Tsunade to this day, referring to her as “that slug woman” due to Tsunade’s ability to summon giant slugs.
Chiyo’s son and his wife were both killed by Kakashi Hatake’s father, the “White Fang of Konoha,” during the Great Ninja War. This tragedy left their only son, Sasori, an orphan, and Chiyo took on the responsibility of raising him. Observing his grief over the loss of his parents, Chiyo decided to teach him puppet jutsu to occupy him with a new interest. Sasori proved to be a genius in puppet jutsu, even possessing the ability to create puppets from human bodies. His very first creations were puppet versions of his own parents. Unbeknownst to Chiyo, however, a dark hatred dwelled in Sasori’s heart. Twenty years before the events of Naruto Part II, Sasori fled the Sand Village and eventually joined Akatsuki. Chiyo confronted her grandson during the “Rescue of Gaara” story arc and defeated him with help from Sakura.
Chiyo sacrificed her life to revive Gaara using a technique originally intended to give life to puppets at the cost of her own.
She possesses abilities such as Reincarnation Jutsu, a technique that allows Chiyo to bring the dead back to life or even give life to a puppet. She is the only one capable of performing this jutsu, but the cost is her own life.
She also utilizes the Ten Puppets of Monzaemon. Chikamatsu Monzaemon was the inventor of shinobi puppet jutsus. These ten puppets were his legacy and are superior to regular puppets. They are designed to work together and are capable of performing powerful jutsus when combined.
