Hitori Gotoh (後ご藤とう ひとり, Gotō Hitori), an extremely timid and introverted first-year student in high school often referred by her bandmates as Bocchi-chan (ぼっちちゃん), is in the first year of Shuka High School and is in charge of the guitar and lyrics of the band, Kessoku Band. She aspires to perform in a band that could showcase even a reserved girl's talent, hence she began playing the guitar. Although her skill is the real deal, she struggles to exhibit it proficiently in a band or in front of an audience.
