I'm not the one to call myself OTAKU(well, you can easily find more enthusiastic IDOL freaks around there), but it made me edit my personal IDOL ranking that the official ranking on "Idol Tanteidan" I bought a few weeks ago was not satisfying for me AT ALL. This is no maniac chart. Consider it is just my self-satisfaction.
