Watashi no Arika

Arika Mamiya, a prominent member of the idol group Lyrical Trick, vanished suddenly and has not been seen since. Over a year later, the group is holding auditions to select new third-generation members. One of the applicants is Nana Miyajima, a blonde girl who draws attention for her distinctiveness. She is later revealed to be Arika's best friend, having joined the group in an effort to investigate what happened to her missing friend.
