Touhou LostWord - Moon EX Battle Stage (3 Star Strategy)

Who am I kidding, I was not going to be satisfied with a 0 star clear. This time I put some thought into it and even brought the spirit cost down.
There is a big question you must answer if you want to get the perfect clear. If you are going to burst the first gauge of Iku and both rabbits in the same turn like you want to, how do you deal with a turn banned from switching and grazing?
You basically have to find a way to break 7 barriers in one turn on Iku at least, and with Rin's and Sagume's Last Word it's possible to full break everyone at once.
Now bringing the cost down is difficult because taking even a single unit out means someone must endure the entire 10 or so turns of the battle, not to mention the loss of damage and breaking.
With this setup it is possible to get enough damage and slot in a barrier restoring card for the last necessary graze but you will need a lot of the best Story Cards.
