Saki Tomogara (輩ともがら 先さき, Tomogara Saki?), is a character in The 100 Girlfriends Who Really, Really, Really, Really, Really Love You. She is Rentarou's 30th girlfriend, a 19-year-old repeated third-year student at Ohananomitsu High School, in class 3-2, and self-proclaimed shadow banchou/delinquent boss at Ohananomitsu High School. Saki is obsessed with the idea of seniority, and dislikes being looked down upon due to her small stature. She repeated her third year on purpose so she would be the oldest (and thus, most important) student enrolled at Ohananomitsu High, and also calls herself the school's "shadow banchou", seeing it to be a fitting title for her. Despite wanting to be respected as a senior, Saki is physically weak, and is bad at physical activity. Rentarou saves her from embarrassing herself after she attempts to break up a fight between some young children (and gets beaten in the process), and she falls in love with him.
