What does this mean and why do I keep getting "NO RANK" at the end? Did I activate easy mode by accident?

As the title says, I haven't been able to unlock this achievement where Gigi is recruited. I don't see them anywhere on the map and I've already cleared the game, so it should have happened by now surely; anyone else have this issue?

Is there anyone havin trouble with this 2 achivements? I defeat ever boss on both difficulties but the achivements just does'nt pop up. I dont even want to try the perfect parry mode thinking of maybe that achivemente is bugged too

its strange.

Hi all! I've just picked up the game on sale, and I've really been enjoying it so far, and I've had no issues up until now!

Not sure why this happens, but I am only given say one or two 'fragments' of the key, and because of the protective bubble around her, I can't actually damage her in any capacity. It seems to soft lock the game so...
