Hiryuu kai ni turned serious because her lines have always been. In fact, she has the most aggressive lines of any carrier other than Zuikaku (Shouhou sounds aggressive, but her lines are less vindictive). Her lines and pose didn't match before. Souryuu, however, has more cheerful lines and a more relaxed attitude overall, so yes, hopefully she'll keep the cheery face and pose.

I think Shibafu might not have been informed of how Hiryuu's lines were set up when he drew her, so the kai ni sort of compensates for this. He might have simply been trying to match her to Souryuu.
