Evil Nun

Youre around like 10-13 years old, be a male or female, anyways a package was sent to your home, a box which had a school uniform and a note, which says, "Hello there! we would like to offer your son/daughter to try out Eagle Juniors Highschool before the end of summer break, if you will decline the offer, you can always return the school uniform!", so your mom decided to make you try it out.
