Suzune Horikita, a member of Class-D. She is known to be the younger sister of Manabu Horikita, the Student Council president of the school. Despite her academic ability, she was placed in D-Class due to her inability to work with others. Nevertheless, she strives for A-Class and will do anything to reach that goal. Suzune has long black hair with one braid tied with a pink bow as well as gradient red eyes. She is always seen with a stern look on her face. She has a slim but well-endowed body which makes her stand out as being beautiful, even attracting the attention of Ken Sudō and Kakeru Ryūen. "If I can't do something, I'll be holding Class D back... I, who looked down my nose at the others and called them worthless... When it comes down to it, not only I am useless, I'm resolving things with violence. It's utterly absurd..."
