Sa Chuushou

Sa Chuushou (茶 仲障 Sa Chūshō) is Sa Enjun's younger brother and the grandfather of Sa Soujun, Sa Sakujun and Sa Kokujun.

Plot
After Enjun's death, Chuushou seizes power in Sa province by imprisoning Eiki and the acting imperial governor. Disregarding the cost and chaos involved, he orders a search for the seals of the previous governor and orders the Satsujinzoku to intercept the new co-governors, Shuurei Kou and Eigetsu Tou. He plans to force the Kou clan into an alliance by marrying Shuurei to one of his grandsons, whom he views as pawns for his ambition.
