Also thanks to the people here I know I can grind 5-2 to get Zuikaku (which I had forgot about). My problem is that the drops hate me, with my bauxite down I'm going to grind 1-5 to try and get Akashi. Admittedly what I said was a bit strong and I do apologize for that. Fair enough.

...but folks have also tried directing you to not worry about Zuikaku and instead to focus on getting Akashi, because she will help you with event preparation a LOT more than Zuikaku will.

And since the event is supposed to be a large scale one, you will want to get as much prep done as early as possible. Hunting for Zuikaku both in game as well as construction will not help you in this regard (and, in fact will only hinder you).
