Kyoto

Kyoto or {闇の砂漠 Desert of Darkness} is one of the Sand Siblings of the Hidden Sand and youngest child of the Fourth Kazekage and Karura, and the younger brother of Temari and Kankurō. Before Gaara's birth, his father had Chiyo seal Shukaku within him, in hopes that Gaara would become the ultimate weapon for Sunagakure as he was the only one of the Kazekage's three children to be compatible with the beast. He was born premature and therefore, was an unusually small and frail infant. Before she died, Karura passionately held her son, vowing to always protect him. Gaara was trained in ninjutsu by his father, but mainly raised by his maternal uncle, Yashamaru.

Legend of Kyoto
Before Karura died from a premature childbirth, she passionately told her son that she would protect him and according to her husband, her love seeped into the sand. However, Kyoto couldn't properly control Ikkaku's powers, killing or injuring several of Suna's shinobi and citizens. Deemed a failure, the Fourth Kazekage chose to test his son, ordering Yashamaru to assassinate him and also tell him that his mother never loved him, and that she was used as a human sacrifice for the sealing process. Gaara failed the test, fully releasing the rampaging Shakaku and Kyoto was felt betrayed, Unleashing the Destructive Ikkaku. to which the Fourth eventually used his Gold Dust to subdue the Ikkaku and Shakaku.
