Author must think they're so clever "it's not isekai! They're just from another planet."
And before you try to mark SpOiLeRs this is from chapter one. I ain't spoiling shit. and neither were the other people literally stating she has the power of "Structural Analysis" and "Structural Editing" which is IN THE DESCRIPTION.
Pace seems a bit fast, but considering that this "saint" thing was the main point from the first chapter, taking 2 chapters to find out who it is seems reasonable.
Wonder how the pace will change and what will happen later.
