|Voice Actress||Saori Hayami|
Ayase Aragaki is a character from Ore no Imouto ga Konna ni Kawaii Wake ga Nai.
An elegant girl who befriended Kirino through their careers as teen models. Like others she has a prejudice against Otaku.
Ayase has a fair complexion with dull blue eyes and medium-length black hair. Most of her bangs are brushed to the right, parted at the center, with her forelocks reaching her shoulders. She is normally shown in her school uniform, but due to being a model she often changes her attire.
At face value, Ayase is a kind and protective friend who cares for others and treats them well to make them happy. She is viewed by others as a beautiful and calm girl, and due to not wanting to cause problems is likely to mask her true opinions or feelings- unless she doesn't like them at all, in which she will be cruel and ruthlessly mean. She is also fairly fickle, willing to turn her back towards others if she finds out they are an Otaku or associate with them. She is also described as a Tsundere, and she can become extremely violent if triggered or annoyed; although it is through implication. She often makes jokes and comments that imply she may be a yandere, and she is easily jealous. Alarmingly, nobody is surprised to find out this is a facet of her personality.
Kyousuke - She will kill him in one route of the visual novel. In a parody of these endings, when Kyousuke notices her behavior he makes a self-referal warning to the Player to save the game before they make the final decision.
Kirino - Initially she is very protective over her and despite having a crush on Kyousuke, she is also shown having feelings for her and was heartbroken to find out that she is an Otaku. A rift came between the girls until Kyousuke claimed it was his fault for "tainting" her, and because she wanted to be friends she pretended to believe him. She tries to be supportive, and because of her begins to dislike them less.
Kyousuke - Due to her lingering feelings for him, she holds a small grudge after he teased her about marriage sometime in the past. In a Season 2 episode she makes a love confession to him, which he rejected despite her claims that she would kill him if he didn't accept it. He tends to panic whenever seeing her with a knife. In one of the endings in the Game she can become pregnant by him.
Kanako - Another classmate and model she knows. They are both prejudice against the otaku culture, but they attempt to tolerate it after they learn of Kirino's interests. While they are friends, she does not think highly of her and can be rude at times.
Kuroneko - They often bicker or argue, viewing each other as love rivals for Kyousuke.
Manami - After Kirino left for a temporary stay in America, they became friends. She is usually the one able to calm Ayase down during her Yandere mood.
The knife is her icon item and something she wields in need of comfort or alarm. She was shown threatening Kyousuke with it to make him study, and also wielded one after finding porno in his home. This knife also appears in the ending theme of the series, which depicts her in chibi form running towards an unseen victim with matching knives in the background. Her episode titles often have knife drawings as well.
