Saki Kasukabe

Saki Kasukabe is one of the main characters from the Genshiken anime and manga.

Saki is a student at Shiou University and the only non-otaku main character. She initially hates otaku and their lifestyle, but is forced to hang around the Genshiken in order to be with her boyfriend Makoto Kousaka. Later on, she is compelled to become a member herself.

As the series progresses, Saki's general attitude and behavior towards Genshiken and its members evolve from barely tolerating them to holding them as dear and valuable friends. She slowly stops abusing Genshiken members (but will still continue teasing them) and even takes part in their activities, though much through her chagrin.

In spite of swearing to destroy Genshiken, she even goes out of her way to save the club (multiple times, in fact) at her own expense.

In Genshiken Nidaime, she has since graduated and is working as an entrepreneur for her fashion line. Outside of a few chapters centered on her, she mostly appears as a supporting character.

In the AWA fics, Saki made her debut at Chapter 16 of All Worlds Alliance Stories.

Appearance
Saki is an attractive, fashionable young woman in her early twenties. Her hair is mid length and is implied to be dyed light brown. She is usually seen with a cigarette in hand, but after a certain incident in the series, she has since quit smoking. Because of her figure (and quite possibly because she's the only other female at the time), Ohno is always pressuring her to cosplay, much to her annoyance.

Personality
Saki is an assertive, down to earth, practical, and at times manipulative individual. She can be easily angered and quite ruthless when the moment calls for it. She spends most of her time physically abusing and teasing the male members of Genshiken, and notably develops an antagonistic friendship with Madarame. She barely tolerates the circle of otakus only due to her boyfriend Makoto Kousaka (who, ironically, is one of the most hardcore otaku of the series), and gets infuriated when people call her one.

Early on, she wants nothing more than to destroy Genshiken to free her boyfriend. In fact, she almost quite literally succeeds in doing so, but saves the group and even returns favors to them out of guilt. In a twist of irony, she has come to the club's aid during times when it is threatened by outside forces.

In contrast to being a hothead, Saki can break down and cry quite easily, especially if she feels ridden with guilt. Although she tends to cause mischief in the club room, she doesn't do it out of malice and will apologize once she hurts anyone's feelings.

Towards the end, Saki has shown she cares for the club and its members, and is emotional at the thought of graduating and leaving it behind.
