He was the son of the Crane Clan Champion and born into greatness. He would however not let this dull the edge of his fighting spirit or dampen his quest for glory. He began his service to the Crane by serving on the Daidoji line against the Lion, fighting against the Akodo. It was during this service he killed the Ikoma Daimyo in personal combat, at only sixteen years of age. He trained alongside the Emperor Hantei XXXVIII in the Kakita Dueling Academy, and the two became good friends. At the age of twenty-one he became the youngest Emerald Champion in history when he beat his own father, Doji Chuai, at the Test of the Emerald Champion.
Satsume was capable of performing his duties as both Crane and Emerald Champion, but when away on official duty he would leave his son, Doji Hoturi in charge of maintaining the Doji household. He wishes that his son will begin to prepare for the challenges to come when Satsume is no longer Champion.
During his time on duty with the Emperor’s guard Satsume was badly injured when defending the Emperor from a ninja infiltration. The injury left Satsume with a scar running from his eyebrow to the corner of his mouth. As the scar healed it resulted in a strange “half grin”, and served as a constant reminder of his loyalty to the Emperor. The scar earned him the name the “Grinning Crane”.
Satsume stepped down as Crane Clan Champion during the Lion / Crane war to prevent a conflict of interest with his position of Emerald Champion
