9nine is a Japanese 5 person unit, formed in 2006, under LesPros entertainment. They receive great support from school girls, ranging from primary school to high school. They are a cluster of colourful personality, who are already actively participating in the media scene as magazine models, actresses and variety regulars. In January 2007, Matsuzawa Azusa (松沢梓) and Wagatsuma Miwako (我妻三輪子) withdrew from 9nine. Shimogaki Madoka (下垣真香) and Kawashima Umika joined in as new members.
