I dont know whether is this kind of event common or not in japan but thats really scary and extreme...a guy cosplaying as ayu and hundreds of fans dancing along with him while on a parade?..and there are people that cosplay her stage outfits too...esp that season outfit ayu used to wear very long ago...thats really funny though!!although its quite happy to see how "otaku" ayu fans can get in japan..anyway u guys should check it out and share your thoughts!~
