Having failed to get into graduate school, with no girlfriend, no money, and no prospects of success with his band, Tsurugi's life has reached rock bottom. One day, after watching the video of Aya Matsuura's song “Momoiro Kataomoi”, he becomes obsessed with the idol singers of “Hello! Project”, and plunges into the idol geek lifestyle. However, as time passes, he and his buddies all find other things just as important as the idols and begin to move on.
山﨑夢羽 (Yamazaki Yuhane) is a Japanese pop singer under Hello! Project as a member of the sub-group Ame no Mori Kawa Umi and the combined group BEYOOOOONDS. She first joined Hello! Project as a member of Hello Pro Kenshuusei in August 2016.
