Saijo Akane, high school student, was recently fired from the band she played drums in because "You're a girl". While Akane is in a state of anger and despair, she receives a suspicious phone call from Genius Musican Naoki Fujitani, who, together with Kazushi Sakamoto and Sho Takaoka ask her "Do you wanna join our band?" This is the story of the beginning of the four members of Ten Blank, who walk the path of music together.
