    WARNING: NEEDS EDITING⚠️ Kaiya Takahashi was an average Class-D student, until she unexpectedly fails a very important maths test. She is then sent to Class 3-E, and starts to be avoided by the ones who were once her friends. She makes new friends that certainly differ themselves from society. And this is quite a change for Kaiya, but a change she is willing to adapt to. What happens when she is told that the actual goal of that class is not only to pass every subject, but to kill their teacher too? Will she give up or join the assassins? I own nothing but the OCs and the plot!
