An older girl who attends Dunbar Junior High School with Melba. Marissa is initially described as a bully who throws “overripe persimmons” at Melba. No one knows how old Marissa is but, due to her size, she is believed to be too old for their seventh-grade class, perhaps even as old as sixteen. Marissa’s father is “a rich minister” in the community, which Melba thinks explains adults inaction when it comes to correcting Marissa’s bad behavior. Unable to understand her behavior, the teachers call Marissa “retarded.” When Melba is assailed by a white man who attempts to rape her, Marissa comes to her rescue by hitting the man over the head with her leather schoolbag and then grabbing Melba’s arm and running away.
