Childhood Friend (Karma x reader)

( I do not own any of the characters, and it will be an insert of the anime. I also don't own any pictures.)

(y/n), also known as Karma's childhood friend, was top of her class, A class. She was perfectly fine, until the day Karma was sent to E class. Soon after, she found one of her fellow classmates messing with an E class student. She protected the E class student in a peacefull manner (she is very weak, and is failing gym) and was sent to E class herself, just to find out she was apart of a class that had to kill an alien like creature before graduation.
