Naki is a very dumb ghoul with a giant heart. He starts off the story as the right hand man to a mafia boss style ghoul. He has had no education, and he mixes up basic concepts like left and right, and he doesn't have a great vocabulary. His arc is about how he grows to be a good leader. In the end, he finds himself a large family and he opens a school for ghouls. (he might be my favorite character)
