In this chapter, Wamu and his companions are walking along the canal towpath, when they encounter a disembodied voice. The voice is that of the water ghost, who is feeding Wamu's hungry ghost. Wamu tells his companions that he has a plan to defeat the ghost, and he asks them to join him in the fight. He explains that they are tied to the ethics of the shaman's community, and it is forbidden for them to harm another. He tells them that he will sell them a bottle of water that contains the spirit of the fireball, a powerful weapon.
