Your character would have to be a brand new student then (as he would have gotten the power just two days ago like all of the others except Ren did). 

Also for the sake of making things easier I am going to have Jester's and Snow's characters just not be there for now (so it would just be Rainer, Ren, Sasha, and Lucian) as they will have just gone home after the battle, not wanting to take part in this anymore.
