Ringi Cordeiro (リンギィ・コルデイロ Ringi Korudeiro) is the daughter of world-renowned MMA champion Mario Cordeiro (should this be a link?). She has lived in Brazil for most of her life, but returned to Japan to visit Yuzuko, her childhood friend. She is an amazing fighter, even to the point that Yuzuko suggested that Natsuo would be a good match for her. When fighting, she maintains an air of naivete, blurting false weaknesses to get her opponent into an opportune position. She oversaw the sparring rematch between Nasuo and Yuzuko, immediately seeing Natsuo's natural talent in the sport. Ringi has then been eager to have her sparring match with Natsuo ever since.
