Birthday: December 22nd. Height: 156cm. Blood Type: A. She isn't very good at studying (test scores average around 50). She has black hair with strands that flick out to the sides. An extremely shy, plain, and inconspicuous middle school girl with zero presence. She is so unremarkable that her classmates can't even remember her name (often calling her "Sumiyama-san" or "Sumikawa-san"). She has no friends. However, her daily life begins to change after Hinata Muto, the school idol, confesses to her, saying he has "always been watching her." Thanks to Hinata, she was briefly able to join the class circle she admired, but Hinata's jealous fans spread slanderous emails. As a result, Hikage is misunderstood by everyone and is currently being bullied. She has a baby face and a small stature, but her body is well-developed; having grown since entering middle school, her uniform is quite tight. However, no one looks at her sexually. The bullying involves physical violence like hitting, judo throws, choking, and pro-wrestling moves, as well as extortion, insidious verbal abuse, hiding her things, and defacing her belongings.
