Morimiya, Aono

森宮蒼乃

Aono is Yorito's older sister, who has been frail since birth and is hospitalized at the start of the story. She possesses a cold demeanor, displaying little emotion, yet she is visibly irritated by Yorito for seemingly ignoring her to attend to other matters. Whenever Yorito brings her a new doll, she glances at it once and tosses it into a nearby basket already filled with other dolls. However, she does not dislike them; in fact, she has a favorite—the first one Yorito gave her. She enjoys origami and is friends with Koyori.
