I've never left a comment here before, but I felt the need to share my opinion. (Will contain some spoilers, but not a whole lot, as I dropped it by chapter 17. But I will tag anything I feel is too spoiler-y)
I started this series with somewhat mid-to-high expectations. The premise of the story, while a bit typical within these genera's, held some hope for originality.
The idea of the FL buffing it up, and dying countless times, within another world that's not originally hers, only to be reincarnated again within a different world sounded interesting to me.
I liked the idea of a noble lady wielding incredible powers, by experiencing and surviving the hardships of literal hell, could have made for a wonderful character with extreme depth and complexity (as well as giving her interesting flaws).
But instead, she...fell completely flat. She feels incredibly boring, predictable, with no form of that depth I was expecting. It all feels 'comedic', at best (and the 'comedy' is rather boring).
Not to mention, she takes on this new role far too easily. She has no memories of the body she has now possessed, yet she takes on this new role far too quickly and easily. She was a normal woman in her first life, then forced to turn into a warrior in her next; but that was through fighting and dying, again and again. Likewise, she was not given those abilities through thin air (at least, from my understanding). So it didn't make much sense to have her adapt so quickly into ladyship. While it may not be as terrifying as fighting giant monsters, I don't think she'd have much knowledge of the political structure, among other things. Very nitpicky of me, I know, but I enjoy characters with depth, and plot lines that make sense.
The other characters are also pretty boring, without anything interesting to add to the story. They all just feel decorative at this point, just to make the FL stand out with her strength. I don't mind a 'marry sue', as long as it's well written, and acknowledges that their MC is perfect. But it feels as if the author isn't even that aware of how 'perfect' she is; just that she's incredibly strong and smart-witted.
Also, while there's not much, I can already feel as if the potential romance in the future will feel forced.:-/ Although one of the ML is pretty adorable; he falls for her way too fast, imo.
It really is a shame, because there's really some interesting elements. When we first come in, we're under the assumption it will be a typical villainess vs heroine kinda thing, but it's actually a murder mystery! Which is pretty neat to me. I also REALLY like the fact that the FL doesn't appreciate the attitude of others, towards the original FL of this story. While yes, she acknowledges that the original FL has done some dumb stuff, she also acknowledges that no one was really there to help support her in any shape way or form; which ultimately forced the original FL into a corner. I also found it sweet that she decides to trust the original FL is not the murderer, not because it's part of her quest, but because she wants too. I don't see that kinda stuff often in these types of stories.
But I can't even care about the plot all that much, because the characters are, again, all incredibly boring. The progression also feels incredibly slow (and I actually enjoy slow burns!). I find myself just forcing myself to read it, so I ended up having to drop it.
In conclusion, it had some interesting elements, but the characters are all boring, thus making the whole thing a chore to read.
This is no shame towards the authors/artists involved, btw; even if it's not something for me, it may be entertaining for some. As I've said, there are some interesting elements to this story, and perhaps it will get better over time. If you find joy within the story, definitely support them.
