Wasureranneyo was formed in 2008. Their major debut came in 2011 with the single “ABC Starting with C” (also stylized as C Kara Hajimaru ABC), used as the ending theme for the anime Gyakkyou Burai Kaiji: Hakairoku Hen. As of May 2018, the only official member is vocalist Takahiro Shibata, so it is now essentially Shibata's solo project.
