Anu

Jao is in a quandary. He can't find work, and he doesn't want to work for Kazematsuri anyway. That doesn't stop the crazy man from sending new recruits to test their skills on Jao.
There is also something going on with Jao's upper class boyfriend, Masahiro. Is he really so busy with his opium business that he struggles to find time for their relationship? Or is he getting tired of slumming it with Jao?
Then Kazematsuri turns up in person to employ Jao to find out what a new gang, the Anu, is doing in Okatsu. At the same time Fan, the daughter of his friend Akai, disappears and Akai hires Jao to find her.
Now Jao has enough money, but he also has several dangerous people to contend with. And he still needs to find out what's really going on with Masahiro.
