She is the fighter of the female Zero pair.     Until they met, both pairs believed they were the only Zero pair to exist. Both teams are experiments created by Nagisa at different times, and the female pair is presumably the first generation. Despite their unusual background, both Kouya and Yamato attend high school, although different ones.    Kouya, unlike Yamato, is very serious and does not take things lightly. She is reserved though Yamato is the only one who is able to get her to open up.     She meets Yamato when they are both young and were trained together to work as the Zero pair. While growing up, her feelings for Yamato grew stronger until both girls had fallen in love with one another.     She is deeply in love with Yamato despite trying to hide it from others. Her cold, aloof exterior is armour for her true feelings; she is truly afraid that she will lose Yamato. It gets to the point that she even ends up throwing up from fear at the idea of being separated from her lover and pair.     It is more than evident that Kouya has had sex with Yamato, as both girls clearly have a physical and romantic relationship alongside their professional relationship as Zero. In an interesting demonstration of the series&#039; fictional world&#039;s rules and expectations of society, Kouya wears fake cat ears despite not being a virgin. Yamato often teases her about it, particularly because Yamato doesn&#039;t try to hide her status. 

Twelve-year old Aoyagi Ritsuka is left with his insane mother as his only family when his brother, Seimei, is killed suddenly. After moving to a new school, he meets Agatsuma Soubi, who claims to have known his brother. Ritsuka eventually discovers that Soubi and Seimei used to be a fighting pair, whereby Soubi was the "Fighter" and Seimei was the "Sacrifice". Now that Seimei is gone, Ritsuka has inherited Soubi, who will become his "Fighter". After learning that Seimei was killed by an organisation known as the "Seven Moons", Ritsuka decides to investigate into his brother's death, with the sometimes useless help of Soubi, along the way.

Aoyagi Ritsuka is one troubled 6th grader. Two years ago, he mysteriously lost his memory and developed an alternate personality. His mother constantly berates (and occasionally beats) him, asking what happened to the "real" Ritsuka, and his only defender and friend, his older brother Seimei, was recently killed. 
Suddenly, Seimei's apparent "friend," Soubi, appears. Soubi tells him that Ritsuka's true name is "Loveless," and that Soubi was assigned by Seimei to take care of Ritsuka and protect him. Ritsuka soon gets sucked into a bizzare underground society where teams of people, a "Fighter Unit," and a "Sacrifice," battle using elaborate and beautifully-phrased spells. 
He seeks both acceptance of himself, and the answer to the mystery of who killed his brother and why.
