Yukino Yukinoshita  

Yukinon, 雪ノ下 雪乃

Yukino is a leader of the service club with only one member until hachiman joins. she's known for being intelligent, attractive, and having an icy personality that earned her the nickname "ice-cold beauty". her sense of noblesse oblige drives her to believe it's her duty to help others, especially those who are lost or naive like yuis. although she can be dismissive of others' naivety, yui still addresses her as "yukinon" with affection.
