今回のイベントでは色々な子の限定グラ(大体鉢巻だけど)が見れて良かった

During this event, there were all sorts of girls that had limited time graphics (it's mostly just headbands though) and it was neat to look at.
While Zuikaku gets an entirely new CG in Winter 2018 Event, the other historical ships just have a headband drawn over their original CG.
