—— Ayame Kajō —— - Ayame is the vice-president of the Student Council at Tokioka Academy and the founder of SOX, a rebel organization dedicated to ending the strict censorship laws. After the arrest of her father, Ayame realized that since she couldn't change her obsession for dirty jokes, she was determined to change the world instead. - - Ayame is a teenage girl with beautiful black hair that goes down to her waist and golden eyes. She has a slim hourglass build with long legs. Ayame wears a normal Japanese school uniform, which consists of a grey blazer, with a red tie, and a contrasting navy blue skirt as well as red and white standard issue dress shoes. She also wears a fake pair of black glasses with false lenses. Her hairstyle is the tuxedo braid. When outside of school, she hikes up her skirt to reveal that she wears thigh-high stockings with a small portion of her thighs slightly exposed. When Ayame acts as her alter-ego, Blue Snow, she wears a white cloak coat that covers most of her body. She also wears her white panties as a mask. - - Ayame takes on an "erodere" personality. One of her most defining traits is that she loves to tell dirty jokes, and does so almost all the time. She is also quite perverted as she also loves to look at adult content, and has even had thoughts about getting a vibrator when she was younger. Because of her love of dirty things, Ayame created an alter-ego named Blue Snow and formed the terrorist organization, SOX, in order to protest the morality laws. -

—— Tanukichi Okuma —— - Tanukichi is a first year student at Tokioka Academy and the childhood best friend of the Student Council president. Tanukichi grew a deep hatred for dirty jokes and vowed to become as pure as his childhood crush, Anna Nishikinomiya, the Student Council president. Though his vow is broken when he becomes a member of SOX. - - Tanukichi is a teenage boy with short brown hair with some fringes and grey eyes. He has a lean and slightly muscular build. His normal attire is his school uniform which consists of a white long sleeve shirt, a red tie, navy blue pants, brown belt and black shoes. - - In general, Tanukichi tends to be a kind, calm and helpful person. He is also very reliable when it comes to saving any situation. He used to love dirty jokes, as he said them all the time with his father. However, after he was arrested and Tanukichi became a social outcast, he grew a heavy disdain for dirty jokes. While he does say dirty things in his alter-ego, he still comments negatively when someone makes a dirty joke. -

—— Anna Nishikinomiya —— - Anna is the daughter of Sophia Nishikinomiya, the president of the PTA, and the childhood love of Tanukichi. - - Anna is an extremely beautiful girl with short silver hair with a black headband, and has turquoise-colored eyes. She is usually seen wearing her Tokioka Academy uniform. - - At first, Anna was a very kind, sweet, and innocent person who made it her goal as Student Council president to end the SOX. Anna admits that she is so naïve when it comes to sexual things that sometimes, she cannot tell what's inappropriate and what isn't. -

—— Hyouka Fuwa —— - Hyouka is the president of the science club at Tokioka Academy. - - Hyouka's main feature is her messy, green hair, which is complemented by her purple eyes and deep bags under her eyes. Her fashion consists of a long, white lab coat on top of her school uniform, but she has been known to wear just her school uniform on occasion. - - Hyouka is a quirky and deadpan girl who is often very quiet and anti-social. It is also safe to assume that she spends most of her time in her laboratory, which is evidenced by her slender (almost starving) body and deep bags under her eyes. She is obsessed with studying how organisms reproduce, as shown through her constant research of insects during sex, and how she is always asking Tanukichi to confirm her hypothesis. She also seems to have a fetish for yaoi, as she is shown to love reading Ayame's and Otome's novel series. -

——- Otome Saotome —— - Otome is the infamous artist who creates pornographic drawings for SOX. - - Otome has short bob cut black hair. She is also much smaller than the average height of students despite being an upperclassman. - - At first, Otome acted very angry and condescending in her first major appearance. When she was awarded her certificate for winning in the Spring Art Show, she ripped the certificate apart, to the surprise of everyone. After Otome joined SOX, she acted much more calm and cool, at least when she wasn't making pornographic drawings. Making pornographic drawings seems to be Otome's passion, and she always acts crazy whenever she thinks or sees something lewd. -

—— Kosuri Onigashira —— - Kosuri is another member of SOX. - - Kosuri is a young girl with short, fuchsia colored hair that largely resembles the tip of a male private part and has green eyes. Her hair tends to lend down whenever she's sad, losing its shape. She also usually wears a blue t-shirt with a yellow tie and blue shorts, along with knee-high striped socks and a handbag that is worn across her torso. - - Kosuri is very manipulative and often uses her young and innocent appearance to lure people into a false sense of trust. -
