Koushaku Reijou no Tashinami  
Login to add items to your list, keep track of your progress, and rate series!
A woman gets hit by a truck and gets sent to the world of an otome game that she had played earlier that same day. However, instead of reincarnating into the main character and focus of the harem, she is fused into the soul of the game's antagonist, the protagonist's rival, and recalled this at the moment she is about to be sentenced to a "bad ending:" isolation in a nunnery.

Watch as she uses the knowledge from the modern world and her past life's job to change this world set in Medieval times!

Somewhat good

So fat it's been an interesting read with decent characters and a decent enough story, thou there is nothing particularly original here it's done well and it's easy and entertaining to read. Also, the art style is nice and the amount of dumbly smiling bishounens is kept in check which is a relief since the artist takes conveying the story seriously and doesn't make a fairy tail out of it with the art, something very common in shoujo.
That said, there are few things I just can't digest in this presentation. The first being that all that innovation is basically transforming that medieval country to Japan's present administration system, which might not sound bad but the issue is that it isn't realistic that the nobility and royalty would allow or turn a blind eye to a fiefdom that empowers the citizens in such a manner and without the leave of the king.
And the second and my main gripe with this manga is that the MC, while interesting, is not very believable or consistent, one thing is knowing how a bank works and thus applying that but the author takes it to levels of knowledge she should not easily poses. Also, and above all, the MC takes over the body of Iris at the breakup of the relation, she has no reason to be depressed or shocked about what happens since from the get go she knows about it already, nor should she have any real feelings for the second prince or her own brother or anyone for that matter, they are just characters in a video game, it's understandable if she gets attached after living there but that's not the case, the truth is all previous memories she has are simply not hers, it's ridiculous to assume she would be so heavily affected by them and that she would be able to so seemingly adopt Iris persona and pretty much loose her real identity completely. Then there is also that she's a firm believer of the church... she's not even from that world, how can she believe in a god she didn't even know about? The MC is riddled with this lapses on the writer's storytelling, I think the author just doesn't use the isekai theme properly and used it only as a tool to have the MC have knowledge about economy and government that she could not have otherwise but she disregards the setting later and thus erred greatly using that theme at all imo.

Capitalism and Taxes Meets Political Intrigues   
Rating: 10.0 / 10.0

...With your healthy side dose of character growth, an empowered female MC, gorgeous art, and everything else that makes a good story. Realistic romances (or lack thereof) and friendships are also present - all the better! But really, stick around for the lessons in how to centralize money and debt, how to transition into different forms of taxation, how to not fall in love only to meet the right person, how to talk to others in high society, how to start and grow a business, how to market, how to import and export goods so as to increase trade between citizens and between different territories, and how to run a proper government.

Come for the gimmicky-sounding isekai otome heroine plot, stay for the sheer amount of competency everyone actually has in this story (and any incompetency is actually explained too, to boot!).

One of the best Isekai   
Rating: 10.0 / 10.0

This is pretty much changed my mind about isekai. I will avoid spoilers, this is too good of a manga and is best read blind. The MC interesting and her knowledge is explained, too many times I've seen an isekai MC know things about modern life but it is never explained or hinted as to how he could have known that or he just knows the thing despite his past life has little to nothing to do with the thing.

Other characters too are interesting, but I won't say more as that goes into spoiler territory. I will admit the manga does speed somethings up, that the novel takes time to further expound on. However the plot doesn't get confusing despite that. And the plot is definitely good, it has everything I could want and more. Also the romance doesn't ruin it, with the MC just falling heads over heels for her love interest like in a lot of isekai (with male and female leads). It doesn't distract from the plot but is instead a nice addition to it.

I absolutely LOVE the story. It is one of the few manga series that I am willing to buy all the books from! The story have a strong female lead who got me cheering "Girl Power!" for.

Great Adaptation so Far   
Rating: N/A

It's only 11 chapter so far, but it's kept true to the storyline without being confusing or too choppy. Plus, it puts in some scenes that aren't in the novel (that I've read but I'm only on ch 57) that fleshes out the setting, without being unnecessary filler, to keep the story flowing smoothly, so kudos to that.
