Rushed ending and plot holes actually don't have to exist together. There wasn't any plot holes but story still feels rushed, I can't say it's not good but it could be better. 15 episodes nothing major, not even a hint what will happen later, then few episodes till end people start missing, last chapters seems to be weirdly put in the story. Rate of the story if someone reads like me in one go isn't consistent this is probably why most people say it's rushed ending. With consistent development and short story some things could be mentioned earlier to set one peace and well developed narrative
What wrong with people? The ending was fine and the story was well written. What do you mean ending was rushed? There literally not single plot was left behind unexplained. I think people need to realize that "good story" is not equal "happy ending".
