The weird thing about this is that in the game, CVL Ryuujou, Hiyou, Jun-yo (I believe) launch their planes onmyouji style. Every other Japanese) CV(L) (outside of Chitose and Chiyoda CVL style) uses arrows to launch their planes, last I checked. I have a hunch that all CV(L)s have the ability to use onmyouji but only a few actually use it as their main launching ability.
