Koari Daikoku is an anime-only character who was to be Ranma's fiancé when Genma traded the young Ranma for food, only for Genma to steal Ranma back. The name 'Kaori Daikoku' means 'Fragrance, God of wealth and trade' which is similar to how Genma traded Ranma for Fish, Rice and two Pickles (Source: Ranma Wikia)
