Hitori (called Bocchi by friends) is a student of Shuka High School and is the lead guitarist and lyricist of Kessoku Band. She is extremely timid and introverted, with a strong desire to perform in a band to highlight her talents. This aspiration led her to take up the guitar. Despite being very skilled, she faces challenges in demonstrating her abilities effectively in front of an audience.
Through her meeting of Nijika Ijichi and Ryo Yamada, her lonely life began to change for the better.
