w (idolmaster)
An idol unit from iDOLM@STER Side-M. It is a two-person group consisting of the 18 year old twin brothers Aoi Kyousuke and Yuusuke.
Both twins used to be professional soccer players before entering the idol business, explaining their soccer motif. Yusuke was injured, so they had to retire early.
They are visually distinguishable primarily by their respective right and left-pointing ahoge.
