• Gyaruko • Azumi Waki • The main character of the series, who despite her name and appearance, is very inexperienced and innocent, and is easily embarrassed over her physique and what she says, as she sometimes accidentally says suggestive things. She has difficulty waking up early, but becomes more active as the day passes. She is also very emotional and becomes easily involved when reading books or watching movies, to the point of crying. She enjoys cooking, and usually makes her own bentos, and can even make bread. She is also terrified of body modifications such as piercings, despite having earrings. She also has an older sister, with whom she often exchanges clothes, including her school uniform; she gets angry, however, after finding out just what her sister does with it. Her name refers to gyaru subculture in Japan. • Otako • Miyu Tomita • One of Galko's friends, an otaku with glasses who likes to mock Galko and gets constantly annoyed by her inability to wake up early. She likes to tell and ask Galko especially about suggestive topics. Between classes, Otako prefers to sit quietly and read. At home she watches anime based on her brother's recommendations. • Ojou • Minami Takahashi • Another of Galko's friends, who is a proper lady from a rich family. She is friendly and somewhat of an airhead. • Charao • Takahiro Sakurai • One of Galko's classmates, a blond boy who is outgoing, popular, and tends to tease Galko. He is the vocalist and bassist of the school's light music club. • Supoo • Daisuke Ono • One of Galko's classmates and Charao's friends. He is the tallest boy at his class. He's a regular at the school's baseball team, and is very careful but proud about his haircut. • Otao • Yoshitsugu Matsuoka • One of Galko's classmates and Charao's friends. A shy otaku boy with glasses who has a crush on Galko. He is shown to be a closet pervert. • Nikuko • Juri Kimura • Another of Galko's classmates, a very plump girl with glasses. She is a member of the girl's futsal team, nicknamed "Sonic Meat" by the boys because she is very fast despite her weight. • Abesen • Yuichi Nakamura • Galko's homeroom teacher. • Okako • Yuko Iida • Galko's very tall classmate who has a bad posture due to her height, and is also interested in the occult. The boys start stalking her after they learn from Galko that she also has big breasts. • Iinchou • Ayaka Suwa • The class president of Galko's class with a serious personality. Her name translates literally into "class president". • Bomuo • Makoto Furukawa • Galko's quiet classmate who was initially annoyed by her, but warms slightly to her after she changes his eye-covering hairstyle. He earned his nickname from Charao after coming to school with bed hair, and Galko fixed his hair for him. He buys beauty products and starts using that as his regular hairstyle, and appears to have developed a crush on her. • Ouji • Yuna Yoshino • Galko's classmate who is very tomboyish. She is often shown talking with Iinchou. Her name translates literally into "Prince". • Galko's sister • Yoko Hikasa • Galko's older sister, who has tanned skin and even bigger breasts than Galko's. She also has a boyfriend, with whom she has engaged in sexual roleplay while wearing her sister's uniform, much to Galko's disgust upon finding out.
