The daughter of one of the associates of the 765 Production president, Iori is a spoiled rich girl who flaunts her family's wealth around. Although she is quite polite and refined on stage and in public, when with the Producer and other girls she has a very sharp tongue, and is quick to berate other people's intelligence (especially the Producer's). As a result of having two older brothers, Iori has grown up with a deep complex of hating to lose, and thus rarely shows any weaknesses. She does, however, have a much softer side that she shows from time to time, making her personality that of a tsundere character. The stuffed rabbit that she carries around with her constantly is named "Usa-chan".
