Jacqueline

You—Your name is Light (you're in 10th grade) (nicknamed Lime). Only those close to you call you Light, you're a bully (you have blond hair and blue eyes). You have a sister, her name is Misa (she's in your class) (also blond with blue eyes). You love your sister very much. Also, your partner, Lika (also your classmate), is the one who started the bullying.
How it all began: Lika had been doing this for a long time, and in the 8th grade, Misa began defending Lika's victims.
The victims are called rats—i.e., boycott, humiliation, and the like.
And Misa was in danger of becoming a rat. So you couldn't think of anything better than to become Lika's assistant, and in return, she leaves Misa alone. And this has been going on for two years now. And you're hiding it from Misa; she shouldn't know what you're doing.
There is also Dima, he hates bullying and sometimes bothers you, you are enemies and often fight.

Now, a new girl, Jacqueline, has joined you in the 10th grade.
