In the
CCG Legend of the Five Rings, Seppun Toshiken became the
Emerald Champion shortly after Emperor
Toturi made his way back to the throne. Toshiken was a just as skillied a duellist as his father
Kakita Toshimoko, but was also resentful of him- while Toshiken knew he was his son, and Toshimoko knew that he was his father, he never publicly acknowledged him as his own, rather leaving him in the care of the Seppun woman who was his mother.
Toshiken's most infamous act was the
Slaughter of the Imperial Court. While he caught a lot of flak from the Crane players
IRL, it was later revealed that his two children were used as a bargaining chip by the
Shadow-influenced
Toturi to do it; even then, Toshiken lost in the deal, as he discovered that the
Lying Darkness had already consumed them.
The
Emerald Champion would eventually go on to redeem himself by turning on his traitorous brother,
Kakita Ichiro, as the courtier was about to stab
the Grey Crane in the back. When his father died in the
Battle of Volturnum, Toshiken would assume his father's name and serve as the
Emerald Champion until his death during the
Four Winds story arc.
