Nwaka serves to antagonize Ezeulu. He goads Ezeulu by publicly insulting Ezeulu's deity, Ulu, and by gossiping that Ezeulu is proud and is trying to become the king of Umuaro. Nwaka urges the men of Umuaro to take actions that are contrary to the actions that Ezeulu advises, and he mocks Ezeulu whenever Ezeulu tries to claim authority.
