Ayase is Kirino's friend and classmate who works as a model alongside her and is also her best friend. Ayase is a friendly, nice, and refined lady, but becomes agitated and somewhat violent at the thought that she is being lied to, which she hates above all else. She tends to believe what she sees on the news. Therefore, she disapproves of anime and manga, calling it a disgusting hobby, especially eroge, due to the media portrayal that otaku will eventually become criminals. Originally she had a simple crush on Kyosuke, thinking of him as Kirino's caring brother. That all changed when she finds out of Kirino's otaku hobby and how he was aware of it and helps support it. She later refers to Kyosuke when she needs to talk about Kirino and her hobby, even asking for his help in making up with Kirino. However, she still dislikes him, believing him to be the reason for Kirino being an otaku. She is also friends with Manami and even exchanged numbers with her.
