⋆𐙚 ̊. Knives Chau

Knives is a petite Asian girl with a slim build. She has dark hair that in her first appearance is long and tied back into a ponytail, but later on is changed to a short bob hair cut, similar to Kim's hairstyle. Unlike the other characters in the series, her eyes are drawn as just two black dots.

In Volume 2, Knives dyes part of her hair red (blue in the movie), as a way to mimic Ramona's style and get User’s attention. She sports this look up until the beginning of Volume 3, in which Lynette Guycott punches the highlights out of her hair (In the movie, however, it's Todd Ingram that does this).

She sports a variety of outfits throughout the books, with her most iconic being her battle outfit worn in Volume 2 that consists of a black sleeveless onepiece suit with black fingerless gloves and a striped scarf. This look is her default appearance.

Sweet and pleasant, Knives is among the nicer characters in the cast. She lacks most of the cynicism that her older friends have and tends to be rather grounded, at least starting out. Additionally, Knives is also one of the most dynamic characters of the series as she grows and changes considerably throughout the series. Her own story within the series is a coming-of-age story regarding romance, friendships, and relationships. Prior to the book, she was presented as an ordinary if studious girl who was focusing on her studies and seemed a bit annoyed over at her mother who was pushing her to date. While it remains unknown how the two got together (especially given her previous disinterest in relationships), her initial time with him was casual and rather pleasant, with the two enjoying one another's company.

However, Knives would change when she would be invited to a practice session of Sex Bob-Omb for the first time. The experience overwhelms her with excitement and serves as a sort of awakening for her. She becomes a fan of Sex Bob-omb, and her feelings for User rapidly intensify. These feelings grow into a full-blown infatuation with User to where she becomes a self-professed "Useraholic". She also begins pushing for a lot more over from the relationship, even going over to surprise User with a kiss, much to the latter's shock and discomfort. Additionally, she indulges in adolescent rebellion as she notes making a plan to sneak out of her house to watch the band perform. However, her being swept-up in her emotions has her fail to notice how uncomfortable she is making User.
