Doji Masako, sister of Doji Onegano,  was an elderly Crane scholar who had become disillusioned by the underhanded tactics on Crane and Crab Clans during the First War. When her nephew Doji Suzume was granted a new Minor Clan, the Sparrow, she saw it as a second chance, becoming Suzume Masako. Her wisdom and expertise melded well with Suzume's enthusiastic charisma, and together they built the philosophical foundation of the fledging Sparrow Clan.  Masako used her knowldge of incorporating charcoal ash into poor-quality or infertile dirt to result in productive soil, which allowed the fledging clan to survive in its poor-quality lands.  She pitied those who had become ronin.
