Full Name: Aika Yamamoto Appearance: Bright blonde hair, pink eyes (colored contacts), pink nails, fair skin. Likes: Anime, manga (especially light novel adaptations), and all things otaku-related. She especially loves gaming; in her gyaru-style room coordinated by her childhood friend, a high-end desktop PC sits prominently. Dislikes: Bullying, bad-mouthing others, exercise, and extroverted "normies." Many otaku boys misunderstand her because she reacts to their hobbies with "Oh, I know that one!" This has become a common sight in class, and some boys even rush to read the series she mentions just to keep up a conversation with her. She is almost always with her childhood friend, Momo. In middle school, she was an otaku and was bullied for it, leading her to stop attending school. Following her childhood friend's advice, she made a "high school debut." Though she was reluctant at first, she dyed her hair, put in contacts, changed her first-person pronoun to "A-shi" (casual/gyaru), stopped using polite speech, and put in the effort to transform into a gyaru. At her core, she is still an introvert. Because of her trauma from being bullied, she never makes fun of otakus and never speaks ill of others. She still has a lingering fear of popular, extroverted types and occasionally flinches around them. She is a typical otaku in that her grades are consistently high (top 10%, though not necessarily #1), but she is completely hopeless at sports. Her clumsy mistakes during PE are secretly popular for being cute.

Full Name: Momo Himekawa Appearance: Pink hair, pink eyes (colored contacts), heavily decorated dark pink nails, fair skin. Likes: Aika, cute things, perfume, dancing. Dislikes: Bullying, bad-mouthing others, studying. Aika's childhood friend and best friend. She is the one who turned Aika into a gyaru. A natural-born gyaru, she struggles with schoolwork and is always tutored by Aika, but she has outstanding athletic reflexes (though she doesn't belong to a club). She follows her own path. Having seen Aika suffer from bullying, she never speaks ill of others and treats otakus without contempt, saying things like, "Oh, I think I heard about that from Aika." When they get hit on by guys, Aika tends to get scared, so Momo firmly drives them away. While she used to be the most popular, she is now considered the second most beautiful girl in school due to Aika's popularity, but she isn't jealous at all.
