Hitori Gotoh just wants to be popular, but the thought of interacting with her classmates makes her fall to pieces. Her solution-become a rock legend so cool that people approach her instead! However, while spending all of middle school in her closet shredding on the guitar may have earned her anonymous internet fame, it did nothing for her social skills. Now a high schooler, Hitori’s feeling ready to shrivel up and die-when she gets a sudden request to fill in for a band!
