Karuizawa was introduced as Hirata's girlfriend from the beginning. Till volume 3 she was simply treated as Hirata's girlfriend who was quite a bitch to other students as she was standing at the top of hierarchy of D-class (so she was also a bitch or was looking down on Ayanokouji).

Her character was developed in volume 4. We find out about her past where she was bullied in middle-school to the degree that she has a scar on her body which will never disappear (possibly a scar from being stabbed). In order to not get bullied in this school she confronted Hirata. So they became a "acting couple' (Hirata is too kind due to the fact that he couldn't help his friend who was bullied in middle-school). Like usual there was a trial which would affect the class point. Basically A-class, B-class, C-class, and D-class were mixed into twelve separate groups. Each of the twelve groups were named after one of the Chinese Zodiacs. There's about 14 people in each group (3 to 4 people from each class). ...I'll explain more about the concept of this trial afterwards (maybe). Anyway the group Ayanokouji was placed in is the Rabbit group. Karuizawa, Yukimura (the guy with glasses), and Hakase (the fat otaku guy) were also in the same group. There were 3 girls from C-class who is a friend of someone who Karuizawa treated with badly. They wanted to make Karuizawa apology to their friend but she declined. The tension escalated to the point where the 3 C-class girls cornered Karuizawa. They started to realise that Karuizawa probably was bullied in middle-school. Ayanokouji and Yukimura was there and the bullying stops. But Karuizawa plays a big role in the trial and especially for Rabbit group. So Ayanokouji plot the 3 C-class girls to physically bully Karuizawa so he can control Karuizawa and blackmail the 3 C-class girls (no one knows that Ayanokouji was the schemer). Since then Karuizawa becomes Ayanokouji's 'pawn' and the reward she will get from it is to 'not get bullied at the school'.

For Kushida....
I'll just list the crimes she committed.

Spoiler for Kushida:

1.) Blackmailing Ayanokouji to keep her true personality a secret from others by threatening to tell the teachers that he raped her (happens in volume 1 and already covered in the manga).
2.) Exposing her 'role' in the trial to Ryuuen in volume 4.
3.) Leaking the sports participant list to C-class which would put D-class in even more dangerous situation and could have made D-class lose so much point (Will explain about the sports day maybe afterwards in detail). She did it so she could get Horikita get expelled by scheming a 'false incident' with C-class by making Horikita the villain.
4.) Again, leaking the test content to C-class in volume 6. Basically each of the class creates an test paper for a other class they choose (and vice-versa). Again, the result of this 'trial' would affect the class point.

So she has put D-class in so much danger by betraying them by scheming with C-class just so she could get Horikita expelled.

Luckily most of her scheme doesnt succeed due to either Ayanokouji or Horikita's action.

So the question is why she hates Horikita so much. Well...

Spoiler for Kushida2:

Kushida was someone who thinks that each person needs something they need to be the best at. In her case it was 'gaining everyone's trust and having their secrets'. In middle-school she behaved and acted similar to how she currently does. She is smiling on the outside and gaining everyone's trust. But behind the scene she was complaining and insulting other students on a internet blog (her name was hidden). But one of her classmates saw the blog and by reading the content that student predicted it was Kushida. That student told the other classmates about that blog where Kushida was insulting them. They cornered Kushida. But Kushida revealed all of the secrets she knows. This caused a massive incident where the whole classmates were fighting against each other. So by the end of their middle-school her class wasnt able to function as a class. The teachers tried to hide to what caused this and the whole incident. But there were rumours of what happened.

Horikita went to the same school as Kushida. But Horikita was a loner who didnt care about others so she couldn't remember Kushida nor the rumour about her. But Kushida thinks different and assumes Horikita knows her past (Horikita comes to remember about the rumour she heard back in middle school in volume 6 because of Kushida's persistence and hate towards her). Hence the reason why she went to so much degree to betray D-class and tries to get Horikita expelled.

See? That's why I hate her so much. She's just too selfish.

Sounds like she needs to get a life.
