To give you an idea of how generic this is by the end of the first chapter our reincarnated japanese person isekai protagonist has : Cheat "limitless magical potential skill" no one else has; Discovers OP training method; Hunts hordes of monsters as a child to power up even more; MCs soul is described as beautiful and "naturally good"; Inspires and unknowingly seduces cousin who now admires MC; Inspires and unknowingly seduces tough bad-boy son of knight family who now admires MC; Inspires and unknowingly seduces child of palace mage sensitive guy musician mage; Inspires and obviously also unknowingly seduces the crown prince as well cause why not; Everyone constantly talks about how strong she is and how her heart is purer than everybody; Cures an epidemic; Invents stoves; Invents modern cosmetic products; In typical harem fashion doesn't know everyone secretly loves and admires and looks up to her because she's just the best at everything ALL DURING CHAPTER 1. If it sounds like you've heard all of this 100 times already it's because it's the same thing as every shounen isekai reincarnation harem story and about half of every shoujo or seinen isekai reincarnation.
Of course, being generic doesn't mean it's bad. Plenty of those series are actually good because instead of focusing on the just the protagonist they focus on comedy or relationships or plot or just anything other than the protagonist because overexposure to a character like that makes things boring if taken too seriously.
Here instead of doing any of that they pivot into the generic revenge power fantasy. And they don't even execute that properly ... most of the characters the MC is taking "revenge" against are literal mind-control drug victims instead of people who are actually evil and deserve it ...
The side characters are many, boring and their stories make little sense within the context of the world. That said the primary antagonist starts off with some really comedic scenes that really make you hate her (in a really good way, like you should hate the antagonist of a revenge fantasy).
The protagonist is generally enjoyable as a character for a while but her big picture plan is dumber and dumber the more you read and it kept making me ask "If you knew this already then why on earth did you do X before this chapter instead of Y". And while she is enjoyable as a character she is always the character everything is focused on and because she takes up all the focus everyone else ends up looking like background decoration.
The art has some amazing pages and some really lazy pages but all the panels that really matter look great. (So long as you can ignore some super lazy digital copy and pasting of backgrounds, which I don't mind)
If you're here for "romance": skip this manga. There's just a few pages of romance, and the romantic interests are just the generic characters you'd find in any harem.
If you're here for "fantasy": skip this manga. The fantasy elements are dumb and contrived.
If you're here cause you love "revenge fantasies" and have already read the few good ones then this one is definitely above average so might be a great choice for you if you don't mind a lot of the revenge targets being mind control victims.
If you're here because you just want a good story and good characters avoid this manga because almost every story arc makes the previous story arc not make sense and the characters outside of the main protagonist and antagonist are not really explored that much and when they are explored it's just generic "revenge fantasy filler character #537"
Personally I was here cause I was in the mood for some good "Villainess" stuff and this didn't work for me at all. I might give it another go when I'm in the mood for a revenge fantasy but the revenge targets being mind control victims is putting me off from it.
