Whether its shoujo or whatever shouldnt deceive you. This is, hands down, the best isekai/reincarnation story. Its not like some others where the MC is just OP with cheats or reincarnates with knowledge of the worlds future (ie. Because its a game or whatever). Rather, the MC comes into the world as the villain, right when the good ending is reached. She then works hard and, though she does use IRL knowledge, the progress she makes and the success she achieves are due to her hard work. She is a... more>> very hard working, intelligent MC, at the same time entertaining. <<less

I've tried to get into the story several times but I inevitably lose interest. It just feels very dry and lackluster, making me feel like I'm reading a dictionary. It's a combination of the way the story is told and the characterizations itself; the story just feels really distant. It's like a subject matter with great potential being taught in very bland way by an incredibly boring professor. What could have been wonderful was completely ruined.

It's really unique and there's also a manga adaption on it! I love it, it's your usual MC recarnates into a different dimension, but I love how strong and clever she is. One my favorites!

Nice, short read. I like the rambles about the economy building. It's kinda jumbled to read all the POV shifts, but I get used to it when good characters pop up.

Because of pics, we get to see Iris (main character) and the other side characters... this time, instead of a bunch of overwhelmingly beautiful men, Iris is quite pretty~~

This is about as good as you can reasonably expect the Otome genre to get. Maybe I'm jaded but it seems like 80% of reincarnation stories are "I woke up in an Otome game and...*insert every sitcom trope*"

It's the best of a bad gener, and probably about the only one I've encountered that passes a Becktel Test (2 named female characters talk about something that isn't a male character. That's literally how low the bar is and most still fail by the time I give up on them).

If you like... more>> the genre you'll love it, if you don't like the genre you'll wonder where the conflict is for the first 40 some chapters. Though

the excommunication ark could have been quite a bit higher stakes it still handled it fairly well and the after portion gave a few side characters some much needed development.

I quite like it, but much prefer the manga over the novel version for some odd reason.

So check out the manga!

Not without flaws true, like others said and pointed out. However, I tend to overlook those type of flaws in favor of major ones found in most of the otome game novels.

Firstly, the characters have depth. Rather then only the MC herself, it has other people's point of views and their personalities are well fleshed out. So the characters feel alive, in short the world itself feels alive. Especially the game heroine's character is very dark and intriguing.

Secondly, the plot is intriguing rather than just bland. Political intigues aside, the... more>> MC has a purpose. The other characters also have their own purposes and that part is well highlighted. So, the events all feel connected to a particular goal rather than random. Even the most simple of character seems like they are hiding more than they look on the surface.

With these two requirements alone, a story becomes readable and enjoyable enough. While lack of minor flaws make it outstanding. So, given there is a severe lack of stories as well qualified as this I'm gonna give it a 5 star regardless of the minor flaws like time skip, MC being perfect and servants being devoted to her etc as they are a part of the plot of this story itself and whether someone likes it or dislikes it varies from person to person. <<less

I first read the manga before I read this LN. MC is quick witted and I like how sometimes MC showed her weak side which is humane. ML was so lovable, ML helps MC behind the scene, and this interaction is LOVE! MC tried her best not to be dependent of ML, and I was screaming silently like "come on!! Be more open to him! Love him!"

The current translator was not so bad, but I prefer the previous translator Thumbs up and keep translating for this ungrateful reader aka... more>> me! Thank you for taking this LN, I can't wait until the next chapter post! Adieu <<less

Tl;dr: Overall nice and mostly enjoyable, flaws are minor.

... more>>

The Seinen / Ore type of title would be something like

"I regained my past life's memories during my bad end as an otome game villainess, but salvage my second life with administration cheats"

Because that's almost all that happens. This obviously isn't the title because it's shoujo, but as it starts out with the MC being expelled, there's little left of the game other than giving a few characters motives or having them reflect on the game's ending actually being disproportional. Other than that, there's remarkably little plot besides the MC overworking herself for 60-80% of the novel.

The MC is surrounded by a ton of high spec characters (that were not part of the game and are thus conveniently loyal after that bad end), some of which are shoujo-type Ikemen. There's a bit of intrigue, but there aren't any conspiracies, that are particularly hard to see through. A certain character's identity was spoiled about 20 chapters early by the translator, but if you can tell who it is and think I spoiled it for you now, you have yourself to blame for opening the spoiler.

It's not like I didn't enjoy reading it, so I'm giving this 4 Stars. The story is missing this little extra that makes me feel like I'm reading something brilliant. Even in terms of romance, almost nothing happens, which is rather untypical for shoujo, so it's occasionally a bit dry.


The translation could be improved and the first translator left a lot of comments while the last annoyingly splits chapters into several pages, sometimes even if there's no second page. The rating doesn't reflect that, but I thought it should be mentioned. <<less

It started out very nice and well-written. The reincarnated story was believable, the MC thinking and emotions are realistic. I like the MC personality, strong and determined, and there is little romance (no MC fall in love too quickly with some random nice handsome rich amazing genius prince).

The reason for the low rating is because I just got bored of it. I just find it repeating itself and cannot be bothered to pick it up again. Maybe someday I will re-read and change my review.

It started out REALLY great, I was hooked! But lately... it just drags on and on. It has some forced, out of character moments that are unnecessary and painful to read. It is probably because the author has run out of material but wants more length. It interrupts the flow of the story. It's common amongst these type of novels, to have entire chapters showing the main character's thought process when the same decision could've taken a few sentences. It is really only there to justify how righteous the main... more>> character is. Will drop. <<less

I started reading this novel because I saw the manga or comic version first. The comic is really good but the story isn't complete yet and I found the light novel. When I read the light novel I got really hooked. I recommend that before reading this LN started first with the comic you can just search for it in manga online with english translation. Hope you find it.

Btw I like how cool, kind, and strong hearted the MC is. I hope you love the MC like I do.

I am hooked to this novel because of the illustration. It is very beautiful ♡. The story also not bad. The plot is not deep. So if you just want a light reading, this is for you. I have hope in the future chapter the author will give a deep and complex plot. I am more looking forward for the romance though. ♡ I love Dean.

The story itself is a typical "reincarnated into villainess noble girl" story. The smart female lead is a point plus to me, because I am... more>> sick reading a dense female lead. Although at beginning MC is supposed to be villainess noble girl, there is no evil bone in the MC. Even the original MC is so kind that she took homeless orphan to her house. It confuse me. How can a kind hearted girl like this has a villain label? <<less

This light novel is interesting. A business woman is reincarnated into a otome game being as "wicked" daughter of a Duke. After her broken engagement with the Second Prince, she starts her journey with her fellows in order to seek the happiness. With her modern knowledge (economic and politic), she stays in her hometown and she trying to built a beautiful place for everyone. And like all story of the time of kings, there are the fight for the throne (fraction, corruption, manipulation...)

It's not a classic reincarnation story with... more>> magic, combat (no many physical) or anything else. So that's why, it's pretty good, interesting and novelty. Moreover, we start the story with a strong and beautiful protagonist so it's perfect for me. <<less

I absolutely LOVE this novel. I love how the MC becomes reliant on herself and doesn't even care about her past grievances. I love her mom, her dad, and her attendants. And I love how people are starting to realize who she truly is. I also love her budding romance, and how that relationship is making them both realize and overcome their weaknesses. Overall, I just love this novel.

This is one of my favorite novels here, translated by one of the best translation groups. I love the fact that the MC is a strong woman, who doesn't simply cry or try her best to win the 'engaged partner', like most of the reincarnated villainess stories. After being expelled from the school and publicly humiliated, she decided to built her reputation little by little, with the help of her trusted personnel. Granted that her knowledge about certain things may be exaggerated a little, other than that, I like the... more>> things that she does to built the land entrusted to her by her dad. The romantic relationship also flows nicely without any cliche story of "love at first sight" or typical shoujo doki-doki moment.

Translation wise: So far the translators did a good job at translating this novel. Thank you to all translators for doing a good job here. <<less

I found Duke Daughter through a manga but the manga version is so slow and I can't bear wait any longer 😣😣😣

So I drown my self in the internet looking for development of Iris life and here I am reading through 74 chapters within a day until my eyes hurt. I've warning myself to stay away from the screen but the story keep provoking me.

I love how the story developed. It's not slow nor fast. The MC is very clever, beautiful, independent, and so kind she's almost perfect.

I hope japtem... more>> continue this light novel soon. I'm carve for DD spoiler and couldn't resist to read the raw which never happen before. I only got slightly hint from the raw, because google Translate did it job awfully. So all I have to do is patiently waiting for the next chapters translated. <<less

My reviews tends to hint at parts in the story, as most reviews do, but I'd still recommend for you to skim or skip this if you want to go into this blind. This may change depending on future chapters.

First of all, I finally got around to reading this... I saw this as a high rated novel after going through my evil-villainess reading spree, and the short story here is: I'm disappointed. Like some other reviews have stated, this whole story feels like a wasted potential- but since the... more>> potential still exists, I'll try to read it till the end.

Like most broken-engagement stories, the "capturable characters" are the "bad guys" and the protagonists are the "good guys." Unfortunately, like most broken-engagement stories, the transition from being a "bad" to being a "good" person is nonexistant- because the "evil" villainess was the good person this whole entire time, even before the reincarnator merged with the protagonist (a counter example to this would be Haunted Duke's Daughter.) This isn't the only novel that has this fault, so I'm not too angry, but...

The protagonist. I know many light/web novels are overran with overpowered protagonists, and I honestly don't mind that if its realistically done and well-written. Unfortunately, here, she's a beautiful young woman with faults that might as well as be her strength. Basically, she's surrounded by people who love her for her faults (ex- her princess-like naivete and kindness). If these faults were expanded on and actually hindered her instead then I wouldn't have been as annoyed. Another reoccurring problem is how her "real world" knowledge seems too broad for any "normal" person from the "real world" and is often used as a plot convenience, but then again, this is a common problem in many LN/WNs.

While the event climaxes and plot twists are predictable and boring, I do love the premise of the main story and the economical and political aspects of her fief. Stories about business and politics nearly always at least get a two star from me, and the writing is decent. It has an addicting quality to it, and I do look forward to seeing how she maneuvers her way to success.

Of course, these aren't all its faults/redeeming qualities, but these are the main things I took note of. All in all, I'd recommend it to any fan of this genre, though I do warn that you shouldn't expect deep and complex characters or a realistic world. <<less

A great read, the otome game reference is only at the beginning of the story since it's a story that's started at the epilogue of the game. The MC is smart and hardworking, not that dense in romantic sense either. While she's moving a lot, there's a lot of things happening behind the scenes from side characters, some of them are aiding her and some of them are hindering her. Though some people write that she seemingly never got adversaries it's a wrong accusation, she does got adversaries, most of... more>> the time the enemies are plotting to strike down her and some of them are actually heavy blow to her image. She needs to work hard to recover from the schemes that's thrown at her. <<less
