Angels of Death Modern Female Self(?) Insert

A girl, often made fun of for making memes and other unladylike things wakes up in a strange place, not remembering much...well, at least not remembering what she was doing last and half of the plotline of one of her favorite anime. Back to her waking up, where is she? What a coincidence, she's been transported into the anime she's forgotten the plot about! Will she be able to change the characters' ending, or will everything go just as planned as in the anime and she's no use to them whatsoever?

Like I'm going to say in the introduction or whatever I called it, my friend is paying me (gasp, paying?!) to insert myself into this, and if the author puts themself into the fanfiction themself isn't called a self-insert, please tell me and I'll change the title. You can insert yourself into this as well ☺This is also the first fanfiction that I haven't deleted when it was still in docs/Grammarly
Special thanks to:
Grammarly-for correcting my grammar and other things like that
My parents-for supplying me with a Chromebook
And especially my friend, for encouraging me to do this (and even offering me money which I might not accept)!
Might be a Zack x Insert
Based off of the anime
