Okay here I am again being super cynical.

For some reason she seems super almighty.  Erasing someone's memory is a very big power.  It's almost god mod like in that sense.  I don't get your limitation if there is one but please either make a hug super huge limitation or try and put the power to the minority.  

Erasing peoples memories is a very big power.  
As for her staying in the girl dorm I'll see what room is availible (she probably will be somewhere close to the guard, cuz you know parents concerns and all o that) 

But as I said before, super cynical so forgive me for that.
