This is by far, THE BEST Overlord fan-fic there is.
It feels like reading the original author's work! It truly is that amazing!
The story development, Ainz' confusion, and other people's assumptions... All these and more!
Tho, it is not without its faults... For one, is the slow update... Well quality work takes time, so there's that.
The other one being, author-dono likes to jump around in timeline and viewpoints quite a bit, without clear explanation.
For example, shalltear's "mission" - where does this fit in the timeline... like before, during or after the alliance?
But overall, this is a damned good fan-fic, if not the best.
Thus, I hope author-dono would continue with the story if at all possible....
