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.

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.

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

While the focus on the business and politic is quite interesting, the pacing is simply too damn fast and MC just keep raking in achievements with minimal problem. Details have been skipped. It feels like everything has been hand waved.

For example, she started a business from nothing to success in two short chapters. And establishing banks in another few chapters. The challenges of making business and financial institution are ignored.

The worst part of the novel though, is the execution of its premise and its characters. No, the MC is not... more>> hated, or even that disgraced. She is loved by many influential people and her own vassals. Her land is rich and she has control over it. She does not need to recover from any hardship that was promised. She just need to build an already reasonably developed land.

And the real 'villains' the 'heroine' and the capture targets are just pathetic spoiled kids.

Decent, cannot say it is great, bit at least decent. <<less

The MC reincarnates as the villainous character in an otome game after failing to take down the in-game heroine. She’s disgraced, heartbroken and expected to return home to face confinement. However with her new awareness, the MC is able to analyze the situation, realizing the inate good within the original character, and utilizing her strengths, resources and social relations to create an alternate path for herself. Extracting herself from the complicated and flawed love polygon of the game to focus on political, socioeconomic issues of the period through various alliances, political and economic reforms and business opportunities.


The original character was usually kind and caring, but due to losing her fiance, acts in a petty way towards the in-game heroine by spreading rumours. While the current MC is indifferent to love but smart and strong-willed, while maintaining the original care the character had for citizens and the poor. While this can be seen from their actions, neither have a truly distinct personality or any characteristics that make the MC stand out from other time travelling or smart leads and the character is quite standard.

Some side characters are introduced, and the servants the MC will use to implement the reforms are likely to be recurring. Aside from the male characters being handsome, there’s nothing distinct about them as they all fawn over the MC’s gentleness, their past debt from being rescued by her and how intellegent the current MC is.

The story starts with a similar concept to Chu Wang Fei and various other Chinese light novels, with a soul arriving in the body of a scorned woman and utilizing the character’s strengths and their own knowledge to carve a better future. However it quickly rises above the petty squabbles and revenge schemes that usually follow. Instead the MC takes an idealistic route of bettering society rather than focusing on romances, becoming a powerful figure within the new world. The plot and tone is similar to Maoyuu Maou Yuusha, as both aim to give two-dimensional and villainous NPCs depth and sympathy through exploring their backgrounds. The feeling it gives also resembles Wolf and Spice i.e. The explanations, economic focus and setting.

The story is not the most original and the plot is somewhat predictable, but the concept is still interesting and has potential. However since only 20 chapters are translated, we have to wait to see how the plot will grow, and how they handle the challenges they face.
However the story already contains a few minor issues:

1. The sheer amount of benefits and resources the MC has (but conveniently failed to notice due to being blinded by love) makes it too easy to make a turn-around. Simply by making use of what’s in front of her, she could’ve improved her future is several ways. The original losing due to a petty scheme and failing to notice these things (but managing to set it up for the MC) seems almost ridiculous.

2. The use of modern knowledge on businesses and government structures is expected, however when the story becomes too specific with its schemes (and the shock of various side characters) and too ambitious in the breadth of industries changed, it becomes arrogant and overbearing. Just because it’s a shocking idea for the period the game is set in doesn’t mean readers in modern times will be impressed (i.e. OMG this thing called chocolate is just too good, how creative and original – not so much for us) while completely disregarding the knowledge and skills available at the time i.e. Money lenders existed and acted as banks so it’s not like it’s a completely new concept.

3. Use of multiple POVs. The story is about the growth and experiences of the MC after her fall from society. Most of the actions and changes are brought on by her while the supporting cast merely carries it out. Using their voices is just repeating or explaining what the MC has already done, making the story over the top with all the praises, and repetitive (she’s kind and smart, we get it). TBH you can just skip the change in POV – the only one worth reading was where her father mentions that he does care about the MC’s feelings.

4. Characters – as mentioned above, they’re all very generic and flat in terms of personality, tone and methods. Even if the author inserted weird quirks, it wouldn’t make them feel realistic or relatable. The MC is near 'perfect' and her personality has no room to grow, and even the people the original body wronged were evil or sinister, so the MC can do no wrong regardless.

I don't have anything negative to say about the story or characters themselves and i'd say that this is a must read, the only reason I didn't give it a 5/5 is because the pacing was a bit off imo, things just happened too fast at times, a problem would occur, and within a couple of chapters would be fixed, now I don't mean it in the sense that the story skips things or that they happen "off camera", but for instance an entire battle would start and end within... more>> a few sentences, the fight would start, someone would charge, cut a couple of people, and done, whole battle over, and that happens quite a few times, if only some plot points were expanded upon a bit it would be perfect. <<less

First off..

  • MC is thought of "mary sue", but personally, I think her past life was just such a workaholic tax accountant that when she started with improving the fief, her knowledge kept on growing that with addition to the new departments she kept on establishing, she felt it possible to put on policies that were "common sense" to make the people's lives more on what was like in the modern times.
  • Male Lead is a "gary stu" but in a way, I could just accept that he is born a prodigy and that by travelling and studying under merchants and having "real life experiences" is what just established the meaningful reason behind being a genius as close as, or even above as the MC with her past life experience and knowledge.
  • I liked how the narrator made the challenges well above the MC's and Male lead's current IQ's making it give them actual hardships and not just focus on the romance.
  • It's almost unfair that the MC already had capable servants at her disposal but it actually tied together the personality of the MC with the workaholic of her past life.

    What I mean by this is that, with her unusual personality of asking for street orphaned children as "presents" for her rather than gems and diamonds and that after her denouncing and being appointed the fief's proxy, there was nothing too different with how she acted in either pre and post past life memories. Her family saw nothing of her changed much other than that she just grew out of being a child and matured into a fine noble -- meaning no one questioned her actions once she did all sorts of reforms with her fief.

  • I love the romance! The progress was neither too slow nor too fast and not unreasonable. They were attracted by the other's work ethics and slowly grew into a romance where they want the other to be by his/her side. They have their sweet moments and tragic moments. The introduction of a potential rival is also not unreasonable and very much in tune with the progress of the story!
Now I'm just waiting for the next chapters but I do hope that the potential love rival can match up to the leading male char.

This is a good read, very recommended! The only trouble is the amount of translator groups this one has. If u can organize how u read it, u can make sense of the story. That just means this is so much of a good story that a lot of translators are willing to translate it! Hehe

That's the end of my review. I hope to see new chapters soon and very much appreciate the work that is being done for this story. Really, I feel so thankful! Definitely one of my faves. :)

It's a pretty good story. I like the characterization but I think there's a lot of unnecessary details. The author has been too focused on describing how brilliant the MC is. There's plenty of skipping scenes, and I need more chemistry between the MC and the ML. By the way, when I read this, up to chapter 85, the website of asian hobbyist cannot be loaded, I wonder why. I hope it will get fixed soon so I can continue reading. Good job, anyway.

i really feel this story is misleading way too much

Everything she does is petty stuff that is justified later. The good guys who are actually s*upid and bad. If they are really s*upid why did she even like the prince. the prince should have atleast few good points. But even the prince is brainless could not do anything. I really hate this. see even if he spoiled by his mother he atleast didnt reject the heroine who is commoner. means he did have some good points. I know the heroine... more>> is weird and all. but still... I dont know what iam saying. but I really dont like the plot.

And the others who opposes the MC is shortsighted, ignorant, or dumb. Everyone that supports her is brilliant and capable. She always succeeds in everything she does. Does she have that much luck. well she did get opposed by few people but she easily solved every issue. wow. <<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.

Good gods, I think I've read ads in the phone book with more words than the small amount of words per chapter this story has to offer. I couldn't get pass chapter 5, which really felt like it should've been part of the first part of chapter 1 - in terms of pacing and length. Everytime the story started to pick up speed, the chapter comes to an abrupt end. Can't find myself willing to recommend this to anyone to read - as there other similar stories out there like... more>> this that're written better with far better pacing. <<less
