This school is full of rich students, their parents either are CEO or officers, they all have many moneys and rights. The students in this school are very afriad about these bad students. Because they fight with the students and did many band things. But actually they did these things to save somebody or for self-defense.
One day, the rich students hitted one of these bad students and he died. So these bad students want to revenge for their friend. But they do not fight with them. They took part in a band match which those rich students took part in too. And they want to beat them.
