Don't care! Push forward as is!

But of course, there's no way that such luck can continue.

I don't know just how many times that I've retreated and had to retry at the pre-boss node

2 nodes before the boss, Chitose suffered heavy damage.

Afterwards, at the pre-boss node, sinking was luckily able to be evaded - which spurred her on continuing to the boss while still having heavy damage.

Grinding for Hatsukaze - the resources dried up and the limit for the times that I can sortie is coming. And still, Hatsukaze isn't dropping. Why isn't it happening for me?
