Nogizaka46, the "official rival" of AKB48 have announced that they will be releasing their debut single on February 22nd, 2012 right after AKB48's 25th single slated to be released on February 15th. At the moment no details about the single have been given beside the date.
I have absolutely no interest in them and I still have no idea what Aki-P is planning to do. But I'm curious to see how this single will fare because they already have quite a fan following but the question is: as the official rival, will they really be able to rival AKB? That is something we'll just have to wait and see.
