Initially, Ayase is quite cold to Shu Ouma due to getting off on the wrong foot with him as a result of him bringing up her disability. Nevertheless, she is a kind and strong-willed person who does all she can to help Funeral Parlor, and doesn't hesitate to give credit where credit is due; when Shu suspects that he cheated in the mock battle due to the fact that he used a Void, Ayase disagrees, saying he simply made use of the one thing he was good at. She is shown to have a crush on Gai Tsutsugami, blushing whenever he compliments her and always being concerned for his safety. However, she denies this whenever it's pointed out to her, claiming she only has respect for him. Ayase doesn't like being pitied for her disability, insisting that it no way inhibits her ability to do her job and getting angry whenever people try to help her. However, this trait ultimately proves to be more trouble than it's worth, since it causes her to overestimate herself and forget that she simply can't do everything that ordinary people can e.g. run away when people attempt to sexually harass her. This insecurity becomes especially apparent when she goes undercover in Tennozu High School, where she's lost her ability to pilot an Endlave, which to her is like losing her legs all over again. As a result, her Void manifests as a pair of Endlave-esque legs, which enable her to sprint at great distances and even fly. Ayase can also be rather hypocritical; she teases Shu for his obvious feelings for Inori Yuzuriha, and yet when Shu brings up her equally obvious feelings for Gai Tsutsugami, she denies them vehemently. She also frequently chews out Shu for wallowing in self-pity, yet does the same thing herself after Gai's death, going so far as to scold Tsugumi by saying that she wouldn't care if she died saving Gai, since to her she's only "half-alive" as it is, words that deeply hurt Tsugumi. However, after gaining the ability to fly using her Void, Ayase no longer complains and seems to regain her confidence.
