Most popular idol for teenager in Japan now

You may have heard AKB48, or Perfume. Or more older one, Morning Musume. Those are for kids in elementary school. Now the most popular idols for teenagers (and Otaku) are actually not humanbeing. They are anime idols, called voal andoroid. Teenagers call them 'Boca-rou' in Japanese pronounciation. If you don't know Naruto, probably you don't have any interest in these clips. But try to watch them. Those are the ones that are understandable for non-teenagers generations. or They held a concert in Tokyo Dome and a lot of fans gathered. Holding a concert in such a big stadium is not something ordinal singers can do. (for instance, when Beatles first came to Japan in 1960's, they held a concert in this stadium.) Wao, it seem they really like her.
