SakuyaA is a pretty terrible shottype!
She has her homing, and...what else? Her attacks are the second-weakest in the game and her Cherry rate is the worst, IIRC. Then there's the usual Sakuya difficulties like highspeed focus and the fact that she has to fight Merlin, although that also applies to SakuyaB who is absolutely broken, so...
Not sure about her bombs since I never use her anymore, but as I recall they're fairly powerful. But other than that, I've never seen her as much more than Homing Reimu-lite :V
and yet i use sakuyab
