Marin Kitagawa is a popular and beautiful high school girl in Gojo's class. She is very interested in cosplay and has tried to make her own, but without much success. By chance, she discovers Gojo can sew and the two bond over their mutual enthusiasm for their respective hobbies. She's a dreadful cook, with a bubbly personality. Her favorite cosplayer is Juju-san, and she'll watch anime and play video games for fun. Kitagawa-san is very emotionally mature, down to earth and respectful.

Yukino is the leader of the Service Club, of which she is the sole member until Hachiman joins her. She is smart, beautiful, and is nicknamed the "Ice-cold Beauty" for her icy demeanor. She has a twisted sense of "noblesse oblige," and believes that it is the duty of the exceptional (in other words, herself) to help the "lost lambs" of the world. Her personality often leads her to be disgusted at the naivety of others, particularly Yui's, and she does not hesitate to show it. Despite this, Yui still affectionately calls her "Yukinon."
