"URN"

- These people, these benders. They took away your mother, the love of my life.

Mrs. Sato was the wife of Hiroshi Sato and the mother of Asami. A loving and caring woman, she was killed by a member of the Agni Kai Triad during a break-in and robbery at the Sato estate.

History
Twelve years before Avatar Korra arrived in Republic City, the Agni Kai Triad broke into and robbed the Sato estate. One of the members killed Mrs. Sato during the break in, which was the primary factor in manifesting Hiroshi's deep hatred toward all benders, eventually causing him to join the Equalists in order to avenge her death.
