She is shown to have no real emotional involvement in her relationship with the player during their dates and sexual encounters and is highly casual in her morning-after greetings to them the player's relationship with her is more of a "friends with benefits" arrangement with dates used as a way for her to check up on the player's progress, and also serve as a test that must be passed to bed her. When the player ends up dating Kyu, dates can be described as more of a test of the player's much-improved abilities, with an eventual reward of sex for performing satisfactorily. Kyu casually flirts with the player along their journey, and also exposes her massive sexual appetite to them through interactions such as exchanging the Dirty Magazine and Tissue box with her for the Weird device and Kyu Plushie, respectively, and also through her enjoyment of sex toys as both common and unique gifts, and her picture messages, wherein she discovers the player's dirty magazine stash and implies she will be using them for sexual purposes, and her use of their washing machine to stimulate herself. She is, however, glad to help them, and shows genuine desire to steer them right in their pursuit to improve their love life. Kyu treats the player in a friendly, supportive manner, although in the early game it is shown that she has no desire to conceal her judgements of the player's total lack of ability to communicate romantically with women. She even collects female underwear because, well, she just really likes the smell."- Game Description As a bisexual, Kyu is often attracted to the same girls you are and isn't afraid to tell you what she'd like to do to them.

She has large, butterfly-like, translucent fairy wings that are patterned in pink, wears light pink stockings which cover the lower parts of her thighs, and wears purple ballerina shoes. She wears a white collared necklace with a pink choker top that has a red heart shape on the front of it. Her default outfit consists of a pink and white baby-doll lingerie with light-pink panties that have a purple butterfly shape attached to the front of them. Her hair also has two decorative silver antennae. She has green eyes that contrast her pink, pig-tailed hair which extends to just above her shoulders. Kyu has a slender physique, with curved hips and large breasts.
She will then add herself to the HunieBee as a datable character. When you try to leave, however, you will be greeted by Kyu, who will tell you that she wants to date you as well.
