Once again, I had this sort of animation in my mind for a transformation that was sort of difficult to translate to comic form. The idea was that the sudden upward motion would make Nanase start falling back, and she'd have to adjust her footing and posture to stay upright. I like the end result, though I don't know if the motion I had in mind comes across.
In any case, I like the idea of a growing morph somehow resulting in looser clothing. Take THAT, expectations!
