The Giglio Nero Famiglia is the original holder of the Mare Rings given to Sepira, the founder, by Checker Face. It was led by Yuni in the future after the early death of her mother, Aria. Three months after Yuni took over the role as the Famiglia's Boss, Genkishi was defeated by Squalo. There was a bargain that Genkishi made up so that the Gesso Famiglia and the Giglio Nero Famiglia could join. The deal was that if Genkishi could defeat Squalo, the Gesso would not bother the Giglio Nero for five years. Genkishi didn't try to win; he wanted the two Famiglias to merge because of his secret loyalty to Byakuran because the latter saved his life from an illness.
