Hitori (sometimes called Bocchi) is an extremely timid and introverted first-year student in high school. She is in charge of the responsibility of playing the lead guitar for 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. Additionally, she possesses a habit of saying "Ah" before she speaks.
