The end to this arc annoys me. I know this is only 29 chapters into the manga, but this whole arc was building up to her discovery. I was anticipating this moment only to have all of the progress lost in the last few pages. I was ok with the slight hints in previous chapters, but in this arc the topic was front and center. It seems like a waste.
Edit: what the hell was I thinking? This is a 1000 chapter manga. Why did I expect anything?
