Ayase is a nice person to her classmates and to Kirino, whom she adores most as her best friend. She is usually soft-spoken and refined, but can also show a more aggressive side, especially when people lie to her, which she hates the most. Her reserved aggressive side often gained her a 'yandere' mark from her peers. Ultimately, however, she is a refined person who retains a sweet and kind personality towards those she cares for. She also appears to show a different kind of affection towards Kirino, showing a certain interest in seeing Kirino shine in whatever she is good at, to the point that Ayase displayed disbelief upon discovering Kirino's hobby. Ayase has always believed that the Kirino who excels in everything is the "true Kirino", only for her belief to be shattered by Kirino herself upon her revelation of how she loved anime, manga and gaming.
