Name: Ruka Takasaki Gender: Female Age: 16 Height: 164cm Weight: 48kg, A-cup An introverted girl bullied in class. She struggles to speak in public and was originally a loner. However, she wasn't mentally strong enough to stay completely alone, so she belonged to a group of introverts. One day, after watching self-improvement videos online, she awakened to fashion, and because she had great raw material, she rapidly transformed into a beauty. She became popular with the opposite sex, but since the concept of having a lover didn't feel real to her, she turned down all confessions. Because of this, boys started seeing her as "unfriendly" and girls as "getting carried away," leaving her more isolated than before and bullied.

Name: Miyu Kanata Gender: Female Age: 17 Height: 157cm Weight: 49kg, A-cup The class madonna. She is sociable, a natural beauty, and an extrovert. However, her true personality is nasty, and if anyone threatens her position, she will scheme and trap them with calculated moves. In this case, that target was Ruka. She dislikes Ruka, and uses a carrot-and-stick approach to manipulate anyone who gets close to Ruka, leading to Ruka's isolation. She actually dislikes men, and the only reason she accepts the madonna position is because it gives her control over the class's decisions. She racks her brains to create a stress-free environment for herself.

Name: Shiina Kino Gender: Female Age: 16 Height: 161cm Weight: 52kg, C-cup Self-proclaimed hanger-on of Miyu. She is intensely curious about interesting things and has absolutely no interest in anything else. She seems to get along well with Miyu, but that's only because Miyu conveniently happens to be an interesting existence for her. She bullies Ruka, but half of her motive is to align herself with Miyu. The other half is because she absolutely loves seeing the sad faces of good-looking people. She excels at both academics and sports. A girl who can do anything, yet is remarkably lacking in humanity alone.
