Yukina Kiritani
Top Heavy Woman, 桐谷 雪那
Yuuya's childhood friend, who is a year older than him, returned home after being away for an extended period. Initially, she maintained a youthful appearance that frequently led people to mistake her for a man. However, upon her return, she adopted a more feminine look. It appears that she can detect Hiyori's presence and may also be aware of Mitsuki's predicament. Hiyori often refers to her as "Top Heavy Woman" due to her large bust size.
