Kikyo Kushida is a student at the Tokyo Metropolitan Advanced Nurturing High School of Class 1-D. She is quite popular in her class as well as the whole school as she aims to befriend everyone. Kikyō boasts tremendous popularity among students as the D-Class' idol who aims to be friends with everyone not just in D-Class, as shown when she extended her hand to Honami Ichinose of B-Class. She attempts to get along well with Suzune Horikita (Kikyō's classmate), but the latter coldly refuses her gestures of friendship numerous times. She openly professed her hatred for Suzune and cursed her repeatedly, which Kiyotaka Ayanokōji unintentionally overheard. After she caught him watching her tantrum, she threatened him not to tell anyone about it, otherwise she would accuse him of sexual assault after purposely grabbing his hand and putting them on her chest to leave fingerprints as false evidence. She also felt no hesitation or uneasiness when she placed his hand on her own breast as evidence of her accusation. She returned to her bubbly self immediately after he promised he'd keep her secret, which left him to question over which personality she displayed was real. Despite her strong disdain for Suzune, she still attempts to befriend her so as to achieve her goal. Although she blackmailed Kiyotaka to keep her secret, she still interacts with him openly after the ordeal. Nevertheless, the latter now treats her with the upmost of caution and suspicion due to her two-faced personality. In a private conversation with Kiyotaka, she revealed that her dislike for Suzune is due to the latter not having a hidden side unlike herself. During this interaction, she acted sincerely for once which was juxtaposed to her violent tendencies Kiyotaka was prepared for. Despite that, part of her other-self was seen later on when she called Kiyotaka mean for being vague in his respond to her question.

She always prepares a to-do-list even when hanging out with her group of 'friends'. After confirming the participants, she will prepare possible courses of action, conversation topics, phrasing, and a-must say sentence beforehand so as to not leave any weaknesses for them to exploit or hold against her. With this, she believes that no weaknesses will accidentally slip out. Additionally, she felt that others won’t have the chance to gossip behind her back and ruin her good girl image especially after she went to extensive lengths to preserve it. Her façade is praiseworthy as she has been able to dupe the majority of her peers into thinking that she was a bubbling and solicitous individual, however, keen observers like Airi Sakura and Ichika Amasawa have been able to deduce that there was something more mysterious, perhaps even sinister, to her than she lets on.
