Kirino Kousaka

**Kirino Kōsaka** (高坂 桐乃, *Kōsaka Kirino*) is Kyousuke's younger sister and the youngest of the two siblings of the Kousaka family. She is an overachiever who seemingly lives a perfect life and is idolized by almost everybody. However, she keeps a big secret from her family — she is an avid otaku and a fan of adult-rated games, especially those involving brother-sister dynamics.

Kyousuke's discovery of this secret led Kirino to introduce him into the world of an *otaku*, and eventually, allowed him to reestablish his role as an older brother to her.

## Description

### Appearance

Kirino is an attractive girl with long hair dyed orange (her real hair color is dark brown) with 2 pink hair clips and blue eyes. She has a small tiger-like tooth that can be often seen when she opens her mouth. Her back-length hair forms two fringes that curl towards her face and has two fringes that point outwards, with two long locks hanging loose on each side of her face. In contrast to Kyousuke and Manami, her choice of clothes reflects current fashion trends and she wears make up, which is suitable for a teenaged model liker her, although she can be seen wearing simple and casual clothes while at home.

### Personality

Kirino is known for having a go-getter attitude. She shows a keen focus on anything she deems interesting, whether it is studying and athletics, or hobby-related activities. This attitude of hers when it comes to school activities has rewarded her with above-average marks, even as she enters the career of modeling. She developed a sort of perfectionist attitude due to becoming an overachiever, which eventually made her more prone to struggling when the odds are against her. When these moments come, however, she displays a more passive side.

During her initial interactions with Kyousuke, she demonstrates an attitude similar to a "*Tsundere*", with the bossy and abusive part more dominant. Although she maintains this attitude, she slowly tries to open up to her brother at times, reluctantly expressing gratitude for things that Kyousuke has done for her. It is later clarified that she does care for Kyousuke, although she chooses indirect methods, sometimes laced with her sharp tongue, to show her sisterly affection for him.

She has a strong "little sister" fetish and owns many adult games with older brother/little sister themes, which is funded by her salary from her modeling job. Despite this, she insists that she does not know why she started liking it, though it is suggested that Kirino has a brother complex and is using the games as a surrogate to this. She often denies such feelings and believes the 2D and 3D worlds should be kept separate. Aside from this, she is also an avid fan of *Stardust☆Witch Meruru* and any series with cute themes in general.

Currently, after Futaba Sakura exposed her to the world, she becomes bratty, selfish and cold-hearted. Even to the point of gaining a crush on Jaune Arc just cause he reminded her of her brother.

## Trivia

* The hair pin of Kirino was given by Kyousuke as a gift when Kyousuke was a first year in middle school. Although, the original hair pin given is not what Kirino usually uses. Kirino had bought similar pins for her daily use.
