Amano is a master of randomly deciding to write things that makes no sense. I don't know why I even bother reading any of her works anymore, I guess I understand why this was dropped to start with.
What do you all mean by trash ending? The author got the axe, she had to discontinue the manga, it's sad but it happens all the time to better series than this, of course the ending would be too abrupt and out of place, imo this was about the most she could made out of it.
