Kaoru Harusaki

About

Kaoru works at Hoshi no Yakata as a slave, and his gentle looks attract bad clients who tend to hurt him. He admits that he has been waiting for someone to take him away from the brothel, but, by the end of the training session organized by Sumiya and Sakurai, Kaoru becomes more confident and vows to leave on his own one day.

When Xiaolong arrives at the brothel, Kaoru is tasked with seeing to him. The two develop a bond, and Xiaolong ultimately chooses to stay and accept Kaoru as his master, though Kaoru is insecure about it after being challenged by Xiaolong's former master, Fei Hua.
