Adult video company Muteki have announced the debut of 'Haruna Aisaka, former member of National Idol Group'. Idol fans took to 2ch and twitter to hunt down possible suspects and believe it to be ex-AKB48 member Naruse Risa.
Naruse Risa was a 4th-gen AKB48 member, and was part of the group from 2007 until her graduation in 2009.
Although still active on twitter, she has stopped blogging and has quietly disappeared from the roster of talents of her old agency.
