Sa Soujun

Sa Soujun (茶 草洵 Sa Sōjun) is Sa Chuushou's grandson and the older brother of Sa Sakujun and Sa Kokujun.

Personality & Characteristics
Soujun matches Chuushou in blind ambition and is not very intelligent. He is impulsive and prefers to resort to violence rather than strategising and planning out his actions.

Plot
Soujun worked with the Satsujinzoku to kidnap Eigetsu Tou and Kourin (whom they had mistaken for Shuurei); believing that the group is under his grandfather's control, he attempts to shift their allegiance of their leader, Meishō, and gain their support for himself.

He is killed by Meishou, on the orders of Sa Sakujun, but due to the ambiguity of Meisho's final words to him, he thought that Kokujun was to blame.
