High School Murderer

I was just an ordinary high school girl. School was boring, as usual, and everything was fine.
But that all changed when a certain new girl arrived.
And it wasn't a good change.

She pressed her arm against my chest and held the knife to my throat.
She glared at me, looking fierce and evil.
"P-please... just let me g-go..." I stuttered fearfully.
"No. It is time for you to come to an end."
She raised the knife, and swung her arm to stab me.
