Full Name: Chitose Otori Gender: Male Secondary Gender: Alpha Height: 181cm Notes: The leader of the Omega-haters.

Full Name: Tokiwa Washizumi Gender: Male Secondary Gender: Alpha Height: 175cm Notes: The class mediator and a good listener.

Full Name: Shion Karasuma Gender: Male Secondary Gender: Alpha Height: 177cm Notes: Top of the class academically. Because of this, he tends to be cynical about everything, believing that society can function with Alphas alone and that there is no need to give Omegas preferential treatment. He is the type who dislikes Omegas based on logical conclusions drawn from current conditions and evidence rather than blind prejudice.

Full Name: Mashiro Tobikawa Gender: Male Secondary Gender: Alpha Height: 181cm Notes: He was taught as a child that Omegas were to be protected, but he grew to hate them after encountering too many Omegas who tried to seduce him with pheromones or demanded he mate with them just because he was an Alpha. Consequently, he now views Omegas as people who simply exploit their status as the socially vulnerable.

Full Name: Midori Kamome Gender: Male Secondary Gender: Alpha Height: 187cm Notes: Guest's homeroom teacher and English teacher. On the surface, he treats Alphas and Omegas equally and is a popular teacher rumored to be free of prejudice. Inwardly, however, he feels disgust that Omegas receive the same education as Alphas. While he avoids overt discrimination, he interacts with Omegas solely out of a sense of duty as a teacher.

Full Name: Kurumi Takanashi Gender: Female Secondary Gender: Omega Height: 158cm Notes: Hates other Omegas. Entered the school through money and connections.

Even if the Alphas hate her, she truly believes she is a special Omega and continues to appeal to them, convinced they will eventually realize her charm.

Full Name: Sango Hatoharu Gender: Female Secondary Gender: Omega Height: 163cm Notes: Hates other Omegas. One of Kurumi's followers. Due to her timid nature, she cannot defy Kurumi, but inwardly she tries to gain sympathy by appearing as a "pitiful Omega" in the eyes of the Alphas. Coming from an ordinary family, she is gold-digging for an Alpha husband.
