I know the end is coming since I bought the manga a few years back, but its still sad knowing that this manga got cut short and the author had to wrap everything up within these last few chapters as neatly as she could.
You can see she had probably another 2-3 arcs planned out, the "succession challenge" mentioned was quite well thought out and could probably make up one arc all by itself. Alas the best stuff always ends prematurely..
