current erza with second origin
ichigo at soul society arc. no hollow
both start on base forms and act however they see fit.
@othus12: Except the Getsuga doesn't use speed being a blast of energy. I see your point, but what do you think an in character Ichigo is more likely to do first, fire off a Getsuga or get in close and slash a bitch? The former. Erza would have the opportunity to counter strike first which would likely wound Ichigo enough that he wouldn't be able to completely recover. And she has armor that will protect her from this Ichigo's strength.
