After Enjun's death, his younger brother Chusho 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, Shurei Hong and Eigetsu To. He plans to force the Hong clan into an alliance by marrying Shurei to one of his grandsons, whom he views as pawns for his ambition. Source :: Wiki
