You,a girl.. just like the others,huh? With a normal life (or not? You choose—) and stuff..

You had a brother, named Vladimir. You were quite close, not that close, but whatever. You both always helped eachother out on things and stuff..

Vladimir : "I know this is weird but i really need help right now..I don't want to attend NRC like Mom asked and stuff — would you mind going..uh..in my place?"

Go in his place to NRC..? An all boys school? No,this was a really bad idea.

As you were about to refuse,You remember that you owed your brother for helping you last time.. Now, you were in the Mirror Chamber, disguised as your brother while you waited for the others to be sorted..great sucess.
