Shukyou (jap.); Zhuxiong (chin.)
Their members are male, wear long red and black robes and have markings near their eyes. They hold great respect for the prowess of Clan Shiyuu. This is shown by the Shukyou members who knelt before Kyou Kai in front of the other assassin clans during their meeting in Qin.
The Shukyou served Clan Shiyuu for over 200 years.
Three of their members are seen killing officials in the Qin capital of Kanyou before heading to the meeting at which other assassin clans were present. Upon hearing of the Shiyuu in their midst, they checked to see if it was the real one before kneeling to the person. They arrived in the palace alongside Kyou Kai to take the king's head and upon seeing Shin, recognize him as the one who killed Jokan. Looking to make up that failure, one of them launches himself at Shin only to be cut down by the boy.
As they observe Kyou Kai fighting Shin, they are shocked when she balances herself on his blade. Clan Gouma sneak up from behind and kill the second member, leaving En Tei as the sole survivor as he duels with a Gouma assassin before stabbing him through the chest with his sword. En Tei escapes capture and meets with Kyou Kai, calling her sword greater than what the legends say. He offers to aid her in any way possible but she refuses and he leaves for his village.
One Shukyou assassin is sent to spy on the king mother, about the man eunuch named Rou Ai. He overhears some important facts, but before he can leave, he is hit by a poison dart.
They are swift, silent assassins who wield swords or short daggers to eliminate their targets. They have great balance and martial skills above the average person.
