8 years ago, Riko was added as one of the adventure group's members, and was given the nickname "Iriko" by Urara. Because her mother is sick, she has to take care of her two younger siblings. The smallest of the group, but at the same time the most mother-like. For obscure reasons everyone fears her "punishments".
